So in fact, the answer to the title "How To Reflash Your ECU" is "Go to your local ECU Tuner". Thanks a lot buddy =P
Michael Wheepy Crousaz Of course man, and not just any local ECU tuner. ECU tunes can pose HUGE issues to your engine's reliability, I doubt any average tuner is capable enough to even understand the program they install into your car. You must go to a professional race engineer, or put your engine life at stake.

Yeah, waste of video.
+Charles Lin Thats why you do it yourself.
'Our friend bought a farm' hahahaahahahaha brilliant!

How to reflash your ecu:
Step 1. Pay someone else to do it.
exactly
+M Bro and still have no idea who.
M Bro I feel ya.i have a 150iq and don't wanna touch it or basically spend 60hrs studying and still have to buy hardware to do it.i gotta Lotta things time aint1.if you've done yours what kinda experience, $,most of all where if they done well.
only tools do it themselves, people with money have someone else do it supporting the work and experience they have
If you look it's kinda worth it since most computers to do it yourself cost over $500 bucks USD and in my case for my car I have to rip both my seat, carpet, and center console just to get to my ECU. (And that's unless you don't do a OBD plug in set up.)
Damn 11 years later watching this is nostalgia at its finest
00:46 The banana theory was hilarious
It helps explain it to dumb people.
i.e. most humans
Am Watching this in 2017 ! 8 years after this episode was aired !
same

Gain on NA cars are minimal. It can vary but mostly around 10%. Turbo's can get over 30% gains.
"long driveway" lmao
Just started watching your latest series... Hungry for more, felt i needed to start at series 1 and see the development of this awesome programme. Mooty (Moog + Marty), you are brilliant. Love the banana analogy. Thank you for your entertainment, advice and education.
very nice, keep it up! I have a stock GTI-r running on increased boost. Goes hard at 15psi
wow that banana and tape description of a reflash was brilliant
"How To Reflash Your ECU" FLUSH MY ASS TITLE
its a workshop commercial
No its an Autometre cobalt blue. We have a video on boost gauge installs if you want to do it yourself. Just click on our username for a list of all our videos.
Yes, it won't do as much, but it depends on how aggressively its tuned from the factory, what kind of fuel it runs from the factory, etc. Timing, injector duty cycle, and choice of octane fuel are of a few parameters that can be tweaked in a way that the customer would find it ideal. On civics, it is even common to set VTEC to engage at low RPMs such as 2,000 to get a little more low end torque out of those little K20s.
Just noticed, moog is a alien, he aint aged, sorry Marty
You can do this to any car. ECU reflashing, however, works best after installing other performance modifications. The ECU reflash makes the car's computer retune the engine to allow all the modifications work together better.
To un-peel, means to put the peeling back on.........
"Farm with a long driveway"
Now we need one on how to flash your ECU yourself.
Ostrich 2.0 rom emulator and the right TunerPro program to do it yourself.
+ a lot of forum reading to get it right :]
The TT has a K03S turbo, the AGU engine in the golf has a regular K03, which will get very hot when delivering boost over about 1 Bar on these engines. When boosting this much on these cars, i would recommend changing the turbo to the K03S which will better witdhstand the load. I work at a VW workshop and has seen my share of broken K03's and 1.8T engines that has had to be replaced because of overheated oil. :)
You can, buy you wont see as much gain in power as with turbo cars. Reprograming the ecu on naturally aspirated cars are usually done after exhaust/intake header/cams etc to optimize the the upgrades you already have.
I like the median lines in your "friends" driveway
Its a premade, one size fits all sort of tune that's applied to the stock computer. Someones already made it before so it doesn't overdo anything, and then packaged it up so that it could be put onto others
the good old days before haltech
I have a hondata flashpro sitting right next to me. Worth every penny.
From what I've read you can re-flash a NA engine but the gains are far smaller than that of boost assisted engines. If you get a couple of % of an NA engine over stock purely by a re-flash you've done well whereas 25% increases on boosted engines in often achievable.
@The1Guitar Yes you could, the result would be that your engine revs higher and you will get a few hp but it will increase fuel consumption as well. You could also change the intake and exhaust and combined with a remap you could add aprox 50 hp.
If there is a tune available ... you can increase your fuel efficiency .. adjust air fuel ratio and do things like raise your red line ... same sorta crap you can do with FI cars.
these guyz know what they are doin for sure!
@princy3010 Ever seen a dyno without putting a wideband in the exhaust? Neither have we.
Ooh, Marty went to the States? He should have done an episode of Mighty Car Mods while he was there. I'd love to see the US Special.
That banana metaphor was bizarre, but it totally makes sense.
"A friend of ours just bought a farm, with a really really long drive way" hahahaha!
@kittymeowbarkify No u dont need. ECUs in car already have EPROMs (can be reflashed wqith OBD2 no opening of ecu needed) or a PROM ( in this case u need to replace the chip inside usualy older cars).
finally a new video i cant get enough of this stuff.
Sorry the General mistake ad that came on before your blog i had to make a comment . Ford did the the forementioned claims with one truck not three
So, leaving the Negative cable off the battery does reset ECU, but better fuel consumption or burn less fuel remains to be seen. But what if you don't have a mass air flow sensor? Would it help to change A/F sensor?
I know this is an old video. but you can easily get 150 kw or 200 hp with a chiptuning on stock engine. you can however get more than that if you do a frontmounted intercooler and 3" downpipe and 2.5" straight exhaust. :)
REMAKE THIS VIDEO!!
hehe, why tho? It's basicly this, Step 1: Take your car to a tuner, the end.
@kittymeowbarkify, Depends on the vehicle. Some have readily accessible EEPROM, others have EEPROM which is locked, and requires a piggyback ECU or Standalone Engine management.
i paid my first Stage 1 Unitronic 650 bucks.. another 170 for Stage 2... and i dont regret it ;)
but iv talked to some professionals.. and they said that increasing the boost by upgrading the ECU and installing some sort of forced induction can put alot more wear on parts in the engine and parts not in the engine... which means you will have to replace them more often or install parts that can handle the extra power... so they recomended not upping the power if you are not gonna replace miscellaneous parts.. (flywheel, air filters, gaskets, etc...)
You can DIY, with programs on the Mototrnic such as NefMotos Bin flasher and using Tunerpro to tune it in realtime. America seems to be the only country where people who modify a base map from the factory think they created it an charge outrageous pricing for so called development when it generally takes a few hours if you understand, and a few days if your starting out. You need a wideband O2 to monitor your air/fuel mixture old school way was do it on an open road,people do it on a dyno now.
hahahah loved the bit about your mates "driveway". great videos guys keep it up!
@ilikethings5 forced induction is the best way to go, since they are small bore they lack toque.. the easiest way to get torque is a turbo and its also alot cheaper to buy a used turbo than to completely build up the motor.
That's so true. I liked the older cars from the 80's and 90's when BMW made sports cars and ///M stood for Motorsport. Now, they build expensive luxury cars with tons of driving aids, and ///M stands for Marketing. It's too bad. E30 and E36 ftw.
do you know electronic throttle controller? it can not only accelerate throttle response but also slow down throttle response of your car. It can provide you with racing car driving experience and also save fuel if you choose the economy mode. It is different from ECU tuning, it does no harm to your car .
this is why i like carburetors
all the power is at your own control
A good flash or a mk4 will run you between 399 and 599. That's just stage 1-2+ then you have big turbo files that cost alot more, not to mention bolt on for our cars are not cheap but you can find them cheap from eBay and amazon but the quality leaves something to be desired. I have a 2004.5 gli and a stage 2 flash takes u from 180hp - 235hp, good gains. Over an na flash. You gotta pay to play;)
Hi guys. Love your show. I know how much you don't love golf gti's but i have a mkv 2008 pirelli. Its a pretty nice car stock 169kw from the factory. I'd love to see you guys do an episode on one of these to find out what you think! Cheers boys
I know it from trying it... you don't get as much of a gain from a Naturally aspirated engine as you would from a turbo, you may get around a 10% bhp increase... with a turbo you make a gain of up to 30% on BHP and another 20% ish on Torque depending on the tuning pack and the engine, if I'm honest if your engine is a non-turbo its allot to spend on a small increase in power, save your money and get a turbo ;)
There is truly nothing more fun that unrestricting your banana.
definitely, although not as much as a turbo car, but you can run a richer mix, it might add about 20-35 hp
"our friends driveway" haha I'll use that next time I get pulled over
I'm a big VAG fan and that banana theory is so true! Moog should make a video of it! ^^, it awesome, love it!
ok. thank you. i was asking cause i have a 92 plymouth laser and i wanted to be able to be able to connect the v3 dsm link. i now have my info so thank you :-)
it's helpful my jetta is outdated need to be reflash good video thnx.
u can fit a bleed off valve to these mk4 golfs n run 12 psi stock but u need to replace engine mounts
my friend with a really long driveway has no road markings and you can get up to around 200kmh, but it's bumpy from when he plows it in the winter, too many hills
You unpealed that banana?!?!? Really, you put the peal back!!!!?!?! So interesting.
l
I am just here to bring you nostalgia
Could you please document the complete ECU flashing steps & their significance using UDS tool, what kind of services we will use for this & purpose of those services ? .Need this answer in steps with explanation
I was exactly 4years and 3 months. When this video came out
that edge dyno place featured in another youtube vid a while back. Had them in there drift 180sx doing skids and douhnuts in the middle of traffic. Hope you dont leave your golf there...
you guys are amazing. why did you stop making videos :(
Now switch that bov for a diverter. wont sound as sexy but will help the turbo much more.
Yeah, these 1.8T's are very slow from the factory, only running about 0.5 bar or 7 psi of boost on a very small Borg Warner K03 turbo. A reflash (cranking the boost up to around 1.1 bar) with no supporting mods can yield as much as a 45hp or 33kw gain. It even boosts your fuel economy by making the car run just a little more lean, and more efficiently.
you guys are funny awesome!! i love that banana part!! good way to metaphorically explain VW's MK4 GTI power!! The MK4 was really the slowest VW made...
@kittymeowbarkify i know on the a4 turbo you could send it in to a company and they reflashed it so you can change setting all from the column.
Banana analogy is the best
@davidabl3 Depends on where you get it, what car you have (or more specifically what engine you have). In the UK a car like the Mk4 golf GTi costs around £350 to remap with a REVO map
@3G4life1990 youll have to a get a full stand alone EMS, like getthe AEM standalone.. that should fix the problem
i have a 2000 tdi jetta. this is what im thinking for my next mod. thnks
Step 1. Grab your laptop, hardware and software that everyone has laying around in their garage.
Step 2. Hook it all up, press some keys on the computer and say "abra-cadabra."
Aussie spec cars are a little bit strange.
On 6:37 you can clearly see that this Golf has a cable driven throttle body.
Euro MK4s (and all of the VAG cars from this generation) with throttle cable cannot have their ECU reflashed via the OBD port, they are not even OBD2 Compatible. This could be done to newer MK4s MY2000+ (Drive By Wire/OBD2)
On DBC cars you have to remove the ECU and either have the new chip with new settings soldered on, or reflash it with some special equipment via its connection pins to the PCB.
nice driveway!! i've got one like that too.. its called the m5 east!!
i hear a whole lot of citing heat as "the enemy" of performance, which of course it is , but i dont hear anyone mentioning three important words that can handily take a major edge off the heat as well as add 10% to the life of your performance mills. now i know some of you gotta be using evans performance coolant, if your not , do the proper research so you dont booger your ride, do the conversion and never open your radiator again.
awesome stuff guys!
make a dvd and ill buy it
I think Peak Performance is at North Parramatta just behind victoria road....
at last new episide of mm!!! Keep it up guys!!!
Of course we love this ...
@twaile Google it or look up PEAK Performance
@ssacproductions REVO
Bruh, 14 years have flown by
haha"our friends driveway" haha I'll use that next time I get pulled over
There simply isn't a "advance timing for more power option" it's give and take, you pay for better gas, you get better performance (if tuned for it, if not your just paying more for gas). Also, if you want to run lean for minimal gains, it's not worth the increased motor temperature...a free 5hp to reduce a motors lifetime from 300 000km to 180 000km simply isn't worth it, and even worse if by chance a part of the cooling system goes and the motor kills itself since it's already running hot.
Great episode guys, keep up the good work
not really because its not just the engine in those cars, it also ties with the suspension, body and so on.
my jetta came with 180HP because 02 and newer got added power :), 01 and older had 150HP
2:56
@BhFanatik17 APR is good to,but revo and giac not much,i have unitronic on my gti whit upgrade intercooler APR,blow of valve forge, clutch master stge 2,complete exahust 3'' neuspeed,waiband,intake ECS and a turbo gt30r,upgrade fuel pump and injector whit the unitronic big turbo tune at 22 psi it run 365 hp and never have a problem,good luck in your proyect and sorry for my english :)
and the funny thing is.. our mate with the really really really long driveway that we did our test on...hes actually got road markings on them ive noticed in that video...hes a weird dude...hahaha
@katanamast279 He said, its about 37-38 kW, thats about 49-50hp.
Man that boost fucks off in a hurry. Bigger turb needed
It was a good analogy tbh
Anyone notice the wheels and engine jutter at about 6:30 when they let off the throttle. Time for bushings, balljoints, and engine mount refresh....
a lot of OBD2 ECU's are flashable with the correct programs and interface
Have you seen any ECUs that have JTAG that you can use to reprogram? I have an EEPROM burner we used to "chip" my friend's OLD school Mazda ('88 with the EPROM / UV erase kind). That I had to disassemble the ECU, unsolder the ROM to re flash. Do you only do Euro or do you do Japanese too? (I don't pay someone else to do it, no matter the risk - not because I'm a cheap bastard, but I lose the opportunity to learn, even if I screw up, once I fix it I know how to do it). I've taken apart a few junk ECUs from different models at the junk yard for s**ts and giggles, but never found the "TDI TDO..." jtag header.
can you mod a celica gt to perform even more
Turbo = Yes, if the whole engine is stock, standard piston etc. You may get 20-30 SAFE HP
Non-Turbo = Around 2-5, 5 if lycky!!
