Personally, music got me into electronics and teenage angst got me into cars, but I would love to see a video of your story, how you learned the things you've learned, and how you've gotten to where you're at!
You really suprised me on this one Paul I’ve watched probably 60 hours of your videos on electronics but this one suprised me I guess you are a jack of all trades master of all.. thanks for takin time from your life to teach us
This video also took me by surprise. As a former tech, I’ve got to say that Mr. Carlson has a firm knowledge of automotive and emissions that would challenge most techs. The state if California would frown on this modification, but obviously it works well and is very well designed.
You not only have electronic skills you have mechanical skills. You explained how the EGR valve works quite well, many people have little clue how it works, and how vaccum effects it. Nice work, you're a educated dude.
Paul, their algorithm took me from a general searching of S-meters to your EGR video here. From my once beloved, '70 LT1-powered, F-bodied '73 RS-Z/28 of decades ago, continually failing the Commonwealth of Virginia emission testing, to today's memory of it all, ...I Thank You for the sense of resolution that I can now enjoy by conjuring-up its small, but important place in my heart as the Winner it always was! Again, ...Masterful Solution!
Ahh the old cc305 cam. I love the part of the video is when you say “my car won’t pass emissions and I’ll show you why”. Too bad you didn’t get a chance to film the trans rebuild that actually lasted for years after no shop could reliably do it. You are truly a master of everything you put your mind to and a wealth of knowledge.
I liked you for the electronics............ you're a petrol head too............. I like you more........... you use your brains to defeat bureaucracy........... you're a God :o)
I don't think the idea was to defeat bureaucracy, but actually deal with the emissions issues of the car and comply with the levels, whilst still keeping the integrity of that car alive. I say well done.
Revenue testing is all this is. My friend swapped a diesel out for gasoline engine and flew through the test. They told my wife she needed to have her diesel fixed because the engine was making so much noise. Flunked her car because the fuel tank filler cap was vented (as diesels should be) She replace the cap to have the car pass (with a gasoline cap) later to have the car stall. I soon realized the fuel tank was collapsing because a non-vented cap was put on to "pass" the emission tests. And you lost a whole weekend... (Average is a new car) Thank you for sharing....
I am more amazed with every video I see, you really understand everything electrical, which is almost everything today. And I admire your teaching/explaining stills, so calm and focused, and just the right amount deep for the newbie listener to understand and follow.
Creative electronic solution to the NOx problem:) Good to see that you properly understand EGR too. You hear so many people say that it takes in the unburnt HCs to be burnt again to lower emissions. But of course 100ppm HC from maybe 1% of the exhaust being returned for recombustion is going to do the square root of nothing. As you correctly describe, it's the inert fill that counts for NOx reduction.
Looks like you got an LT-1 there.. and you can hear that cam as soon as it idles, like music. yes the OBD1 was a primitive system but also easy to work with. I got my 1st mechanic job in 1984, people were still driving muscle cars around for daily drivers back then, a 68 Camaro was less than 20 yrs old. more recently I was also an inspector. we didn't see rotisserie restorations back then, and I remember the really nice cars would run you $20K on a lot, in the 80's that was all the money...I'm glad you're so well rounded in skillsets. people like me absorb a wide variety of technical, mechanical and industrial content. go watch how they cold-roll giant steel pipes. we're talking 1/2 or 1 inch plate going through rollers with no heat? crazy!
wow thats a detailed work around - down under its just brakes & general condition, rust & function ect and we thought that was bad!!. good presentation as always
When I started watching I expected you to explain that low vacuum was preventing the EGR from opening, and of course the cam lowered vacuum even further. I was surprised that you were still using vacuum on the valve. I was expecting you were going to substitute a solenoid to drive the pintle valve. All good. Love the stuff that you can craft together.
PAUL that was CLASS... another invention for you box(which must be bulging by now) My dad(74) asked me why you dont make money off it coz it's a great invention, i had to explain to him thats not how you do thing's, & that you believe things should be free & knowledge shared freely.. he thinks your MAD!! but i convinced him your right.. WHICH YOU ARE OF COURSE!!! CLASS PROJECT!! CLASS VIDEO!! & CAN'T WAIT UNTIL THE NEXT INVENTION.. : )
You explain things so clearly, and your sense of humour is brilliant ..." I will start the car so you can see why it failed emissions...". We have Chev 350s fitted to our Holdens and they are a favourite choice for get up and...gone!. Keep up the good work.
Thanks Colin, Thankfully "Air Care" is now finished as of Jan 2015. Now I don't have to deal with paying into a system that "clearly" was designed just to collect money.
I love these videos. I wish we did more practical stuff in school like what you do in your videos. I know people with PhD's in electrical engineering that would have a very hard time keeping up with stuff you do on a daily basis. You have a lot of hands-on experience that really shows. I wish I was a fly on the wall in your lab over the years! I once had an issue with my old Ford Ranger passing emissions. It had high NOx, but I had no idea how the EGR worked back then. I noticed they poked the probe up the tailpipe about 2' so I went back to my shop and drilled some holes in the tailpipe just after the cat. After running it through a second time, I just barely passed. I think this was because the NOx was just going out the holes I drilled and not far back enough to the probe they were using to test. I had holes to patch at the end of the day, but at least I passed :)
@ Dustin Korpi - '' I wish I was a fly on the wall in your lab over the years!'' - You'd have been swatted & killed, nobody wants a Fly buzzing around them in a Confined Space like that Lab. LOL. - But I do understand your feeling, I feel the same way . . . . want to learn how he does it all.
I'm a master emission certified specialist here in the states for both gasoline and diesel. I am also a massive hot rodder and love to build fast cars. I have spent 2 decades trying to explain to people that there is always a proper way to get good reliable street horsepower from your car or truck without ripping out the emissions systems. Most of the time these kids come into my shop with a car that sounds loud and gets 5 mpg and a check engine light on and needs a waiver for there emissions and I get to tell them they dont qualify because all there factory equipment has to be in place. Doesn't have to be working but it has to be on the vehicle and not tampered with. But 500 hp and passing emissions is totally doable they just dont think it is...Great video and nice job showing how to improve the EGR flow...
A wiseguy's solution to get a modded Pontiac to pass emissions. Well done! VW should have consulted you. I learned something I will never use but thoroughly enjoyed to watch. The lesson is that it's all about finding out what the test is testing and then figuring out a novel solution to pass the test. Listening to your many videos while you explain electronic circuits, its very refreshing to hear the detailed descriptions. Plenty of "oh, that's what that's for" moments. You must have a shed bursting full of old gear you've collected and friends who need your expertise.
The first video of yours that I watched was the one with the transmitter tour. I've watched a bunch since then. I come from a background of my mother being an assembler for 50+ years. She started out at Motorola when it was a hole in the wall in Ft.Lauderdale. I used to help her assemble as a kid and learned a bunch. She now makes interconnect cables that plug you in to the monitoring devices when you are in a hospital bed. I went off and honed my skills doing automotive performance. I have been doing that for close to 20 years. I had great respect for your informative videos on electronics analysis/repair and now have a greater respect knowing you are a car performance enthusiast. Very cool! This video is a great insight to get a modified more modern vehicle to pass. When we had emissions here I could easily get a carb'd vehicle to pass the test ( with hollowed cats ). Great info and explanation!! Best regards~ Don.
Great video here Mr. Carlson, love the creativity! Came here looking for vids on de-soldering potentiometers from circuit boards and end up watching 4th gen EGR mods, lol!
Its always fun playing with the O2 sensors when you mod the exhaust too, even the other sensors or maybe even adding others since the ecu can't really tell you everything even on OBD2. I love the electronics but this is just awesome, a gearhead who loves electronics!!
I dont know when I first watched this vid.... But do believe its the first Carlson vid I ever watched. It made me subscribe. Blast to see it in my suggestions again
I stumbled upon this particular video. I am a gear head and now trying to get into electronics. You have made a serious impression on me. THANKS for your great video content.
My Brother is a tube amp guru. He does a lot of the same things that you are doing. Fender guitar amps, etc. I am an old dog trying to learn new tricks. Thanks Again!
I've seen all your videos at least 2 times now. On second thought, I think this solution deserves a "patent" no less. I also agree with John Lake. And please, do not make too short videos. Regards Kay/OZ1HJG
You have awesome content! This one was surprising and old. But I found very interesting. I too have had inspection troubles in Missouri. I’ve had to manipulate oxygen sensors to pass inspection. But this is way more. A lot more than I could ever do is a weekend warrior. But am I right in saying that you’re not skirting the system you were actually taking a system and making it better so it passes? That is really cool! I’m really not a fan of all the admissions BS. I think they actually contribute more to the problem than they do actually making things more efficient. Either way. Very cool video, you do some great stuff!!
Dynamite EGR redesign, a pretty simple weekend design yet complex and very cool. I like to see other tech's work for the simple reason that a lot of people try and really make a mess of things, or are very good in their work. That issue would make a very interesting TV show to me, being on the bench myself since late 1970's I've seen it all!. The printed outcome of your emissions after your black box mod. was very impressive, and made sense also with what you did on the EGR. My career as an Electronic Tech. has been long lived, and I love it, - Auto Mechanics since early 1980's (not as a f/t career) - I have to say that Electronics has been very good to me! - I didn't know you were into Mechanics until you're EGR video. I've seen a bunch of your videos and I have to say they're not only interesting and informative in the way you present them to those who are beginners, intermediate, as well as those like myself with decades of fun and profit doing what I love, so I have to give you credit where credit is due, and whether it's a repair, mod. or restoration you've shown some of the most interesting radio equipment on the bench. Your work area seems a bit cramped, but obviously that's how you wanted to set up shop and I know it's cozy for you sitting there!. Gotta love IT.
+Jeff L Thanks for the kind words Jeff! Glad your enjoying the video's. You mention many area's I try to focus on. Appealing to all levels of experience is difficult, but necessary. At least the more experienced in electronics can skip ahead in the video, where as, if I make things short, the info isn't there. Thanks for taking the time to write!
Man, I see this is his first video. I see the Mr. Carlson im used to seeing on the bench, now outside of his garage, shades on, talkin about these emissions tests we all fail. Bust open the hood of the car and im like ok ok I see ya Mr. Carlson, little black box with a "rather simple design actually", eyyyyy now thats the Carlson that sounds a bit more familiar. Then when you said we would go to the lab im thinking, oh man, its my man, going to the lab uh ohhhhh uh ohhhh and im cheesing the whole time, and once you gave the pan of the lab I said to myself. Now thats Mr. Carlson right there, humbled as can be, but wanted to show us that lab. Made me smile for real. Love this guy man, he's got that engineering swagger with that Pontiac. Once the hood was popped and he pointed out the box, I envisioned the frame freezing, the west coast gangster rap start playing and them pixelated shades sliding straight over his eyes! HA
I, a mechanic has been watching your electronic videos for over a year now, heck maybe even two. And that's been my second biggest interest. And now I hear you do cars? Welp, you better make more vehicular content :I
Repairing vintage electronics and classic V8 cars... my two favorite hobbies. Fortunately where I live we do not have emissions testing to deal with. I was laughing when you mentioned smashing the honeycomb out of a catalyst with a broom. I have never done such a thing to a clogged cat.
I had a pretty cool device I'm my mom's 96 grand am. I was 16 and was allowed to drive a few miles to my girlfriend's house and she checked the milage to verify. I pulled the cluster fuse and put 2 spade lugs into the fuse box I ran them to a small and box with a dpdt rocker on/on switch with a push button in parallel and a fuse of course. I used this to turn the cluster on and off and the push button to spot check my speed. cruise control even worked with the cluster off. I used the second pole of the switch to turn on and off some under dash neon lights so there were no questions asked. I just velcroed it beside the shifter and filled the tank before returning the car after my and my girlfriend's joyrides. Ferris Bueller eat your heart out. Lol
Man..... I thought you lived in Canada.....?.... I didn't know the folks above America played with wonderful toy, like such.... lol... Another very well put together video and explained with great detail! Thank you for the effort and time you have put forth to do so. Drew
Thanks - this just gave me an idea on how to get my '06 Ion Redline with Comp Pkg to pass emissions....emissions are fine...but the CEL comes on with an 1182 code (manifold pressure sensor) when it gets over 28 degrees c, or when I turn the air conditioner on ! It started doing this about 2 years after it was new. I've resorted to clearing the code during the winter time and getting the emissions done then, instead of when it was actually due, in the summer, when the CEL is constantly on. The 04-07 RedLine Comps were a marketing gimmick from GM Performance, it was their flagship car in 06, and only made 1,089 of them, and each dealer was only given 1 per year for their showroom. I bought the only one allotted to Atlanta that year. Most of them have this problem, and since there are so few, GM performance division never bothered to provide a fix. I'm thinking it is a temp/air density issue with the MAF sensor and the MAP, and the sensor readings fall just outside of the computer's tolerances. Maybe I'll ask this on your Patreon link, since I'm a Patreon Patron of Mr. Carlson's lab. I'm surprised your a car guy...that's so cool.
Having watched this and glanced through the comments I couldn't hep but think about the recent story about VW emission's scandal. However your system actually reduces the emission's during normal driving . If I get the idea correct this is not to fool the emission's test this is actually making a proper difference during normal running. excellent stuff keep the vids coming.
+Sean Regan The idea was to make the car pass, the result was even cleaner emissions than stock. That was a surprise considering the size of the cam. Thanks for your comment!
funnily, it's still emission tampering. VW has an engine that pass these test with flying colors WITHOUT an catalitic converter and it's blocked by governing bodies like CARB simply because it doesnt have one. It passes the emission test but not visual one, so they cannot use it. Dealing with bureaucracy is much harder than dealing with reality, logic and engineering
Here in the People's Republic of Chicago we only test vehicles with OBD2 but I certainly appreciate this idea. I have used FRS radios for remote control of things, intercoms, a number of things they weren't intended for.
The algorithm just sent me here. You are an amazing person. I too am fairly reserved in my public life. I just let all the wild out by driving fast cars 😂
This is a bad ass machine. Actually one of my unicorns....5th Gen F body with LS1 is the be all end all for me....my preference has always been with the T/A over the Camaro. Beautiful ride, sir.
+Mr Carlson's Lab .....Carb and points....sounds like my 1973 Corvette....350 and Edelbrock aluminum heads, Comp Cams 280 roller, sounds almost like your Pontiac...fortunately...73 is the last year here in Calif before smog test bi-annual....
Paul, you had better get the hell out of Dodge City. Since you posted this video, the RCMP has a warent out for your arrest for emission fraud. Seriously, great video. I spent a year in Canada and loved it up there. John
this system could totally be used for homemade electronic boost control with some tweaks. adding this to my project bookmarks! the 3914 usage is exactly what i was looking for
Thanks again. Great video and explanation. And (unexpectedly) you are also a "car" guy. Add another feather in your bonnet. Next step? Drive that car over to Jay Leno's Garage. And THAT would merge my two UA-cam worlds. Thanks again Mr Carlson.
Very clever circuit Mr. Carlson. Looks like a 1995 Firebird LT1? with some aftermarket headers. I looked at the LM3914. It seems to be intended for an audio level VU meter (10 Leds) driver. Interesting the way you used it to calibrate the linear resistor.
Mr. Carlson has a Hot Rod that makes my day, You would like my 2015 Chevy SS from Australia, LS3 Corvette engine with a Caddy LSA Supercharger. Now if i coul djust fix these old radios i have in the basement. Great video as usual, so glad to see you have some gas in the blood too.
Haha! ANOTHER electronics geek who loves high performance cars. I LOVE IT!!! My 2013 Mustang GT puts out 730 HP. Let's just say I've had a few issues with emissions. :>) I'd love to go 1 on 1 with your Firebird on an open highway. I wouldn't even think about going 1 on 1 with you with so much as an OHM meter. LOL
This is an awesome project. The mechanical EGR was a design fiasco to help auto manufacturers comply with political goals, while most other counties in the world continued polluting like crazy or should I say accurately, "pollute more." Mechanical EGRs would often fail only because of carbon buildup and the driver never got any feedback that the EGR was failing to work properly. Then the government put the burden also on the individual as factories and power plants had raging smoke stacks. You should have produced this video years ago! Produce RELEVANT videos like this because it is so helpful, educational and informative.
This is a great channel. Nice to see a fellow Canadian making such informative videos. Took a few videos to figure that out. some of the hints was A) The tools saying Mastercraft - House brand of Canadian tire, B) Forget which video but the radio broadcast mentioning province in one of the voices that I am used to hearing on the radio and C) the use of AirCare as that alosne narrowed you down to British Columbia as our program in ontario is called Drive Clean and the .ca being used in the website listed in the bottom of the page but I see that it is now a cancelled program which you are lucky as ours is still in effect but the test is limited to 7- 20 year old cars and once a car has turned 20 then it is exempt. I love this channel and I am the type of person that is interested in seeing the insides of any electronics no matter when they are made as it is very intriguing to see how something performed its functions many years ago.
Yea, those Firebirds and Cameros run hot right out of the gate, I dread working on them for this reason. They wanted them to run warm and they do, at about 235f under the best of conditions. Get stuck in traffic on a hot day and you will lose a head gasket, the bypass doors were left open on the radiator and I recommend refitting doors to the fan assy to avoid this problem. It's almost a mid engine vehicle and no fun to work on, so, I try to do the repair right so it doesn't need doing again. I learned something about this system from you, and it doesn't surprise me to find the EGR is not working as well as it could work. Cooling it down will help with NOX and also cylinder sealing, and keeping these heads sealed is a challenge.
You are a very interesting guy. From old school radios to cars. Awesome content.
Thanks Keith!
Personally, music got me into electronics and teenage angst got me into cars, but I would love to see a video of your story, how you learned the things you've learned, and how you've gotten to where you're at!

Just awesome!

you apparently failed critical thinking.
I don't think the idea was to defeat bureaucracy, but actually deal with the emissions issues of the car and comply with the levels, whilst still keeping the integrity of that car alive. I say well done.

Simon Parkinson Thanks for your comment Simon!
Yes, the EGR gas reduces peak combustion temperature, and reduces knocking with less-than-premium fuel.
man i have been watching you for quite a while this is not the car i expected you to drive, love what you do.
Holy Moses! Mr. C has a hot rod! Sounds great too!

And in next week he will show us how to build a simple Flux capacitor, only running from a single AA battery! :-)
I am a patreon subscriber, love your videos. I am still learning. I am a mechanic by trade for the last 25 years and that is great! Keep it up
Wow not only are you a electronics Genius you sound to be also a great Mechanic. I admired your wisdom.
You could have sold that black box to VW eh? ;)
real1rube ...(maybe he did already!)
GOOD ONE!!!
Hahahaha
nah they would prob blocked it with a law.
@@Bewefau There's plenty of states in the US, where this would still not pass. California, is one of them.

Agreed. If a SRT challenger can make nearly 500HP and pass emissions from the factory it can be done.

Thankfully, AirCare is finished now!
Now I understand where you are working out of ! BC! Yay! You are one of our own !
Great video here Mr. Carlson, love the creativity! Came here looking for vids on de-soldering potentiometers from circuit boards and end up watching 4th gen EGR mods, lol!
Thanks! Funny how youtube has a way of doing that :^)
Of all of the projects you've done; this is VERY cool!
Thanks Ted! At the time, I really had no choice, It was either build this or the car sat.
Its always fun playing with the O2 sensors when you mod the exhaust too, even the other sensors or maybe even adding others since the ecu can't really tell you everything even on OBD2. I love the electronics but this is just awesome, a gearhead who loves electronics!!
You are full of surprises sir.
Awesome and elegant how your getting better readings than the average. Super clean and effective. This gives me ideas for the cars I work on.
Thanks
You're welcome!
I dont know when I first watched this vid.... But do believe its the first Carlson vid I ever watched. It made me subscribe. Blast to see it in my suggestions again
Paul what don't you know how to do,... your explanations are clean informative and precise .
keep it up man love your vids..👍
I was shocked to see you and this car lol, very nice!
Thanks Justin!
you are a legend mr. carlson, i hope to be as skilled as you someday
I love the application of the LM3914. I have thought of similar uses for it as an A/D convertor.
I stumbled upon this particular video. I am a gear head and now trying to get into electronics. You have made a serious impression on me. THANKS for your great video content.
Glad you're enjoying the video's Michael. Thanks for your feedback!
My Brother is a tube amp guru. He does a lot of the same things that you are doing. Fender guitar amps, etc. I am an old dog trying to learn new tricks. Thanks Again!
Well who knew he is a motor head also . That bird sounds quite lumpy . Nice to see :)
I've seen all your videos at least 2 times now.
On second thought, I think this solution deserves a "patent" no less. I also agree with John Lake.
And please, do not make too short videos.
Regards Kay/OZ1HJG
Haha, it sounds like you have a 4" flowmaster setup. I like that rumble. Two thumbs up !!!
LOL ....you got it. You know your exhaust systems! Thanks Clark!
Wow, didn’t expect that!! Lol love the channel even more now!!
I did not understand all of the workings of the electronics but the concept sounds pretty cool to me ! Nice !
We used to put studded tires on these so you would get an idle test only. Ahh.. memories. Cool to see you are from 604
You have awesome content! This one was surprising and old. But I found very interesting. I too have had inspection troubles in Missouri. I’ve had to manipulate oxygen sensors to pass inspection. But this is way more. A lot more than I could ever do is a weekend warrior. But am I right in saying that you’re not skirting the system you were actually taking a system and making it better so it passes? That is really cool! I’m really not a fan of all the admissions BS. I think they actually contribute more to the problem than they do actually making things more efficient. Either way. Very cool video, you do some great stuff!!
Dynamite EGR redesign, a pretty simple weekend design yet complex and very cool. I like to see other tech's work for the simple reason that a lot of people try and really make a mess of things, or are very good in their work. That issue would make a very interesting TV show to me, being on the bench myself since late 1970's I've seen it all!. The printed outcome of your emissions after your black box mod. was very impressive, and made sense also with what you did on the EGR. My career as an Electronic Tech. has been long lived, and I love it, - Auto Mechanics since early 1980's (not as a f/t career) - I have to say that Electronics has been very good to me! - I didn't know you were into Mechanics until you're EGR video. I've seen a bunch of your videos and I have to say they're not only interesting and informative in the way you present them to those who are beginners, intermediate, as well as those like myself with decades of fun and profit doing what I love, so I have to give you credit where credit is due, and whether it's a repair, mod. or restoration you've shown some of the most interesting radio equipment on the bench. Your work area seems a bit cramped, but obviously that's how you wanted to set up shop and I know it's cozy for you sitting there!. Gotta love IT.
+Jeff L Thanks for the kind words Jeff! Glad your enjoying the video's. You mention many area's I try to focus on. Appealing to all levels of experience is difficult, but necessary. At least the more experienced in electronics can skip ahead in the video, where as, if I make things short, the info isn't there. Thanks for taking the time to write!
Sweet.... +1
Love that you took the time to fully explain the EGR function, thx.
Your welcome!
Love the creative use of the LM3914!
Man, I see this is his first video. I see the Mr. Carlson im used to seeing on the bench, now outside of his garage, shades on, talkin about these emissions tests we all fail. Bust open the hood of the car and im like ok ok I see ya Mr. Carlson, little black box with a "rather simple design actually", eyyyyy now thats the Carlson that sounds a bit more familiar. Then when you said we would go to the lab im thinking, oh man, its my man, going to the lab uh ohhhhh uh ohhhh and im cheesing the whole time, and once you gave the pan of the lab I said to myself. Now thats Mr. Carlson right there, humbled as can be, but wanted to show us that lab. Made me smile for real. Love this guy man, he's got that engineering swagger with that Pontiac. Once the hood was popped and he pointed out the box, I envisioned the frame freezing, the west coast gangster rap start playing and them pixelated shades sliding straight over his eyes! HA
some of the most informative videos i have ever seen on youtube :)
Thanks! I always try to dig in a little deeper.
I, a mechanic has been watching your electronic videos for over a year now, heck maybe even two. And that's been my second biggest interest. And now I hear you do cars? Welp, you better make more vehicular content :I
Repairing vintage electronics and classic V8 cars... my two favorite hobbies.
Fortunately where I live we do not have emissions testing to deal with. I was laughing when you mentioned smashing the honeycomb out of a catalyst with a broom. I have never done such a thing to a clogged cat.
Nice going with the E.G.R. control modification !
I had a pretty cool device I'm my mom's 96 grand am. I was 16 and was allowed to drive a few miles to my girlfriend's house and she checked the milage to verify. I pulled the cluster fuse and put 2 spade lugs into the fuse box I ran them to a small and box with a dpdt rocker on/on switch with a push button in parallel and a fuse of course. I used this to turn the cluster on and off and the push button to spot check my speed. cruise control even worked with the cluster off. I used the second pole of the switch to turn on and off some under dash neon lights so there were no questions asked. I just velcroed it beside the shifter and filled the tank before returning the car after my and my girlfriend's joyrides. Ferris Bueller eat your heart out. Lol
wow. thanks for lifting my spirit. student for life.
Nice work, hang on to that Pontiac it's fast becoming a rare collectors item.
Man..... I thought you lived in Canada.....?.... I didn't know the folks above America played with wonderful toy, like such.... lol... Another very well put together video and explained with great detail! Thank you for the effort and time you have put forth to do so. Drew
Glad you enjoyed Drew!
Car sounds fantastic! Sound almost like a full race cam in there...
Im a master tech L1 and L2 in texas, i like how you made that with the car , i made one too a while back. Keep up the great work
Aahhhh, so Mr C is 'the boss' from STREETROD!!! I'd never race you for pink slips now! Respect-
😲 Mr Carlson is a Revhead? great video & nice car Paul.
Dude I thought you were just an electronics geek but you're a really cool dude nice car
Another excellent articulate explanation of a misunderstood Exhaust Gas Return system.
A very good video and project my friend.
Thanks - this just gave me an idea on how to get my '06 Ion Redline with Comp Pkg to pass emissions....emissions are fine...but the CEL comes on with an 1182 code (manifold pressure sensor) when it gets over 28 degrees c, or when I turn the air conditioner on ! It started doing this about 2 years after it was new. I've resorted to clearing the code during the winter time and getting the emissions done then, instead of when it was actually due, in the summer, when the CEL is constantly on. The 04-07 RedLine Comps were a marketing gimmick from GM Performance, it was their flagship car in 06, and only made 1,089 of them, and each dealer was only given 1 per year for their showroom. I bought the only one allotted to Atlanta that year. Most of them have this problem, and since there are so few, GM performance division never bothered to provide a fix. I'm thinking it is a temp/air density issue with the MAF sensor and the MAP, and the sensor readings fall just outside of the computer's tolerances. Maybe I'll ask this on your Patreon link, since I'm a Patreon Patron of Mr. Carlson's lab. I'm surprised your a car guy...that's so cool.
Having watched this and glanced through the comments I couldn't hep but think about the recent story about VW emission's scandal. However your system actually reduces the emission's during normal driving . If I get the idea correct this is not to fool the emission's test this is actually making a proper difference during normal running. excellent stuff keep the vids coming.
+Sean Regan
The idea was to make the car pass, the result was even cleaner emissions than stock. That was a surprise considering the size of the cam. Thanks for your comment!
funnily, it's still emission tampering. VW has an engine that pass these test with flying colors WITHOUT an catalitic converter and it's blocked by governing bodies like CARB simply because it doesnt have one. It passes the emission test but not visual one, so they cannot use it. Dealing with bureaucracy is much harder than dealing with reality, logic and engineering
Here in the People's Republic of Chicago we only test vehicles with OBD2 but I certainly appreciate this idea. I have used FRS radios for remote control of things, intercoms, a number of things they weren't intended for.
Man...!!! Do I wish you were my neighbor!!! 😎 Love your channel. You have a new subscriber...
The algorithm just sent me here. You are an amazing person. I too am fairly reserved in my public life. I just let all the wild out by driving fast cars 😂
This is a bad ass machine. Actually one of my unicorns....5th Gen F body with LS1 is the be all end all for me....my preference has always been with the T/A over the Camaro. Beautiful ride, sir.
I....would never have taken you as a guy who likes his cars to chop. I like your channel WAYYY more as of now.
The beast makes clean emissions. Ok, well.... Cleaner anyways.
Just carburetors and breaker points?
+Mr Carlson's Lab .....Carb and points....sounds like my 1973 Corvette....350 and Edelbrock aluminum heads, Comp Cams 280 roller, sounds almost like your Pontiac...fortunately...73 is the last year here in Calif before smog test bi-annual....
Mr Carlson's Lab this is amazing.
Does it run 10's?
nice beast
" I'm Quite Surprised Mr. Carlson , well done ! !
Thanks!
I remain in total awe! Live long and prosper.
Thanks Rich!
Paul, you had better get the hell out of Dodge City. Since you posted this video, the RCMP has a warent out for your arrest for emission fraud. Seriously, great video. I spent a year in Canada and loved it up there. John
this system could totally be used for homemade electronic boost control with some tweaks. adding this to my project bookmarks! the 3914 usage is exactly what i was looking for
this is just my kind of project,,,,the frs is over the top showing off, the box to test it is the kind of thing I expect from a master tech
Thats truly impressive how huge of a difference you can make by just adding more precise control over the EGR valve, but it makes sense.
+compactc9
Thanks!
Thanks again. Great video and explanation. And (unexpectedly) you are also a "car" guy.
Add another feather in your bonnet.
Next step? Drive that car over to Jay Leno's Garage.
And THAT would merge my two UA-cam worlds.
Thanks again Mr Carlson.
it is incredible every time I see it I am impressed again
sound awesome the car you look like the terminator in the dark glasses ha great video sir what a brilliant unit
Good job Paul.
Thanks Jerold!
electronics and pontiacs... love it! :) we have a 67 gto and a 67 bonnie, and an 08 G8
Great bit of kit that , nice fix.
Very clever circuit Mr. Carlson. Looks like a 1995 Firebird LT1? with some aftermarket headers. I looked at the LM3914. It
seems to be intended for an audio level VU meter (10 Leds) driver. Interesting the way you used it to calibrate the linear
resistor.
Mr. Carlson has a Hot Rod that makes my day, You would like my 2015 Chevy SS from Australia, LS3 Corvette engine with a Caddy LSA Supercharger. Now if i coul djust fix these old radios i have in the basement. Great video as usual, so glad to see you have some gas in the blood too.
That exaust reallyyyy sounds great!
Thanks Willy!
Haha! ANOTHER electronics geek who loves high performance cars. I LOVE IT!!! My 2013 Mustang GT puts out 730 HP. Let's just say I've had a few issues with emissions. :>) I'd love to go 1 on 1 with your Firebird on an open highway. I wouldn't even think about going 1 on 1 with you with so much as an OHM meter. LOL
Carlson you are amazing!
Thanks!
This is an awesome project. The mechanical EGR was a design fiasco to help auto manufacturers comply with political goals, while most other counties in the world continued polluting like crazy or should I say accurately, "pollute more." Mechanical EGRs would often fail only because of carbon buildup and the driver never got any feedback that the EGR was failing to work properly. Then the government put the burden also on the individual as factories and power plants had raging smoke stacks.
You should have produced this video years ago! Produce RELEVANT videos like this because it is so helpful, educational and informative.
That beast sounds mean, Paul. As an electronics technician, I appreciate your channel... but your stock just went WAY up! Thank you for sharing.
Thanks for the kind words Brett!
Very clever...Thanks for the video.
This is a great channel. Nice to see a fellow Canadian making such informative videos. Took a few videos to figure that out. some of the hints was A) The tools saying Mastercraft - House brand of Canadian tire, B) Forget which video but the radio broadcast mentioning province in one of the voices that I am used to hearing on the radio and C) the use of AirCare as that alosne narrowed you down to British Columbia as our program in ontario is called Drive Clean and the .ca being used in the website listed in the bottom of the page but I see that it is now a cancelled program which you are lucky as ours is still in effect but the test is limited to 7- 20 year old cars and once a car has turned 20 then it is exempt.
I love this channel and I am the type of person that is interested in seeing the insides of any electronics no matter when they are made as it is very intriguing to see how something performed its functions many years ago.
Glad you're enjoying the video's Sarah. Thanks for your kind words too!
What a beast! Bi-turbo? I'm so jelly!
Car sounds great Paul.
+Jason Parker
Thanks Jason!
Yea, those Firebirds and Cameros run hot right out of the gate, I dread working on them for this reason.
They wanted them to run warm and they do, at about 235f under the best of conditions. Get stuck in traffic on a hot day and you will lose a head gasket, the bypass doors were left open on the radiator and I recommend refitting doors to the fan assy to avoid this problem.
It's almost a mid engine vehicle and no fun to work on, so, I try to do the repair right so it doesn't need doing again.
I learned something about this system from you, and it doesn't surprise me to find the EGR is not working as well as it could work. Cooling it down will help with NOX and also cylinder sealing, and keeping these heads sealed is a challenge.
