Absolutely enjoy watching your videos. I’m not personally working on my car, but still going through the project and you my friend make things very easy to understand as far as what you’re doing, what the mods do, where you can get them, etc. Love how the car is turning out and can’t wait to see the final! Keep it up!
You’re definitely doing everything the right way..can’t wait for the revision and see how that car rips!!
I've stumbled across your 19T video and I've been hooked watching the entire series. Your filming style is refreshing. Keep being you!
That was a lot of work! Nice to see this car running finally! Great video 👏
Glad to see you back brotha. Per the norm, car is coming along nicely.
Awesome video, looking forward to the next one!
your nexsys kit and it's issues is precisely why i'm going Vehicular DIY's method of the "Fat Bunny" B58 conversion instead.
Love the videos man you have made some nice progress on this IS.
So clean
Great content! Keep it coming! Appreciate all the details and yes zero-60 is so helpful as well! Would love to see some draggy numbers when it’s all dialed in!
Thanks! I actually did some Dragy runs two days ago on 93 octane and ~21.5psi. They weren’t shabby. Once I get it dialed in I plan to do some Dragy content.
+1 for the Spartan Beast!
Earned that shirt at Killington Vermont. One of the hardest Spartan courses that exist.
Neatly done👌🏻👌🏻👌🏻
Definitely deserve more subscribers, too many vloggers getting more attention than us DIYers. I’m also in the Midwest lol, but Madison WI.
It’s a grind for sure.
Bro, you went all out, you have everything things you can think of for this build. Can wait to see you put this on the dyno. I'm still debate if I want to go with RB turbo like your or top mount turbo. I think your build is a reliable set up that you can use as daily driving.
Thanks! The crazy thing is I’m not done yet. I have a whole lot more planned for the build. I’ve been busy with work which is why I haven’t had as much time to spend on the build, along with more content.
The RBs are great and I have around 3500 miles on them. I’m estimating that I’m around 650-675 whp. I’m definitely doing a dyno video in the spring.
@@midwestbmw1292 how do you like current PI set up, I see most guys now go with the manifold style. I see that you beefed up the drivetrain and suspension.
ITS PAUL WALL BABY WHAT IT DO
Great video!
Is there any particular reason you chose to install the fuel rail pressure sensor on the front bung rather than the rear?
The starter is directly below the rear bung so I was concerned about fitment.
Great video. Thanks for sharing it. Are you datazap logs available for public viewing? If so could you please share the link?
This is the base map log that I sent my tuner
datazap.me/u/9inedays/log-1659055761?log=0&data=21
Hey thanks for the great video. Did you by chance install a Schottky or flyback diode with your solid state relay for the fuel pump?
…no but I plan to. For me everything has continued to work flawlessly but for others I’ve talked to they needed the fly back diode and when they installed it everything worked fine. Based on what I know you should install it on the SSR.
@@midwestbmw1292 thanks for the quick reply. Do you have a plan yet for which diode you will install? I originally ordered the MSD relay planning to plug it right into my Precision Raceworks harness, but now I'm rethinking that and think I should get a traditional SSR like yours and add a diode.
love the build man, any plans for this thing soon?
As of right now I’m enjoying the car for the summer. It’s on the third revision from Wedge Performance and it’s and absolute animal. This winter I’m going one of two ways with the build but haven’t decided. Hopefully I’ll get some driving footage up soon.
Can the NHD interact with the Motiv module? or you need anything additional to tune the engine? Thanks for the great content!
Motiv Reflex+ is wired into the DME and therefore accessible over CAN Bus via OB2 port. It work’s separately but in conjunction with MHD app. The Tuner you choose will need to support Motiv and write in PI control file into the tune. Essentially the injector map the Tuner puts in place on ReFlex+ will work alongside the tune file uploaded through MHD. Hope that makes sense.
It does! thanks for taking the time to explain! (already Subscribed to your channel btw 😎)@@midwestbmw1292
Hey man, with the solid state relay, did you use a diode?
The guys at Zero to 60 and I did a bunch of research online and had many conversations about it. The consensus was that it wasn’t needed on our application. So far there have been no issues on my end or with others I’m in daily contact with who have the same set up.
Yo so if u get the reflex and use the pressure sensor in the port injection rail u no longer need the Hobbs switch ?
That is correct. The pressure switch will trigger the secondary LPFP based off of rail pressure reference instead of boost reference with the Hobbs switch.
What adapter u use to connect the reflex 10bar sensor to the port injection rail?
Check out the response to the same question from 3 days ago.
Good job👍🏻 where did you buy wires for secondary fuel pump including relay ?
When I bought the fuel pump from Precision Race Works a wiring harness and relay came with it. However it was for use with a Hobbs switch. So when I switched to the solid state relay controlled by rail pressure reference and ReFlex I simply bought wire from a local parts store and wired it all myself. It’s not to hard to do.
@midwestbmw1292 is there any way I can modify the precision racewerks harness to have reflex control the secondary pump? Or should I just buy the relay you linked and wire it that way?
@@midwestbmw1292what gauge wire you use for the SSR?
Would you mind creating maybe a youtube short or possibly linking to your walnut blasting setup? Im in the market for one currently.
Give me a few days, maybe sooner and I’ll do a community post on it.
Hey man. What exhaust tips are those?
Mashimarho carbon fiber
So the relay is needed? I just purchased the pi plate. Stage 3 fuel pump. Same fuel lines. And reflex+
Yes. Reflex will trigger the relay to trigger the secondary fuel pump to increase rail pressure once PI injectors are triggered.
@@midwestbmw1292happen to have link to the relay u used?
I’m currently installing my port injection plate. I’m curious what did you use for the 0-10 bar sensor as the sensor is 1/8npt threads and doesn’t screw in directly to the PI Plate.
Here ya go.

@@midwestbmw1292 Thanks! I really appreciate the quick reply. I went ahead and ordered it. I really want to get my 335is started tomorrow so I might just throw in the hobbs switch for now. I’ve pretty much mirrored your build as far as fueling goes but I went the single turbo route. I’m super excited to start it up. All I have left after the port injection plate is the upgraded fuel pump. I’m still a little confused about the wiring for the SSR but it doesn’t seem too bad.
Glad to help. Let me know if you get hung up on the relay and wiring. It’s not that bad once you understand why and how it all works.
@@midwestbmw1292 Sounds good! Again, I appreciate the help. If I get caught up with the install, i’ll for sure get back to you.
@@midwestbmw1292I’m having an issue with my second pump not coming on. Could you help me out?
Dope video that will definitely help with my instal. I’m putting a list of all the parts I need to go PI using the MR+(motive reflex plus) for my N54 but there is just one thing I don’t understand. I’m aware that MR+ has a feature that allows it to smartly manage the secondary LPFP but I’m not sure how it sends the signal to it.
I currently have my secondary LPFP running of a 10bar boost pressure sensor but I’d like to fully take advantage of the MR+ features.
So how would one send the power/signal from the MR+ to the secondary pump and is there maybe a link to the parts I would need?
I should have spent time adding more detail in the video but I was rushed for time when I was installing.
After you read this comment rewatch the video and it will make more sense.
When you buy a LPFP set up that has a secondary, typically it is controlled by a Hobbs switch (boost reference) like it sounds like you’re doing. When using the MR+ you have an option to use a rail fuel pressure reference. I have the Motive pressure switch installed in my PI rail and then have it plugged into the MR+. From the MR+ there is a wire to a solid state relay (the one next to my battery at the end of the video). That SSR is then wired to the secondary LPFP.
What this does is replace the boost reference with a rail pressure reference, which most tuners will unanimously agree is a much, much better reference. In fact it’s one of the key benefits of MR+. So what happens is this: Once rail pressure drops, as the primary runs out of steam up top, the pressure switch kicks off a signal to MR+ which then fires the SSR which kicks in the secondary LPFP. Once rail pressure is regained, it shuts the relay off. Hope this helps.
@@midwestbmw1292 thanks for the fast response!
And yes currently just running my secondary LPFP off hobs switch.
You have a link to the solid state relay you’re running? And well what kind of wiring did you end up using to plug the MR+ to the relay?
@@ItsKhazzz it’s a Haltech relay. It was like $44. It’s a pretty robust, tried and true unit in the mod community. Part info below.
HT-030202 Solid State Relay 100 AMP
Item# HT-030202
You’ll want to use the “ground switch method” to wire it, which the instructions for are provided with the relay. If not you can Google them. I used the cig lighter outlet that’s located in the passenger side footwell to get my 12v switched.
You will not need to install the little diode that comes with the relay.
@@midwestbmw1292 awesome, I definitely will order the relay right away.
I have never messes with electrical stuff this way besides the simple plug and play stuff.
But I want to learn how it’s all set up so I have a better understanding as well as just know how it all works lol.
Thanks you’re really helpful and digging through forums there seems to be many people also confused with this process just with there was a great DIY video
@@ItsKhazzz glad to help. Believe me it took weeks to figure out how to do it and do it right. Very little info at all out there about it. In fact most of the help came from Andrew from Zero to 60. Him and I texted back and forth for days about it.
Great video man! What part of Ohio are you in? I'm in the Dayton area!
Lorain County west of Cleveland
I’m in Dayton from time to time as I have family there.
Will the motiv mhd sensor work
I believe that’s if you’re running Motiv ReFlex Lite. I’m running the Reflex+
Did u have to but the relay for the secondary fuel pump separately
Yeah I bought it from Haltech. I think it was like $50. I tapped the switched 12v from the cigarette lighter socket in the passenger footwell. Some have tapped into the exhaust flapper wire in the driver side taillight access.
Fosho thank u for the info
@@midwestbmw1292 I wish you were close to Kansas City. But how do you wire the solid state into the motiv reflex?
How did you connect flex fuel wire to dme?
There is a flex fuel sensor harness that Motiv sells for ReFlex+. In fact I believe it comes with the unit. It connects into the ethanol sensor and the other end connects to the ReFlex harness. Then the main Reflex harness has a wire that taps into a pin on the DME harness. That pin is what converts the signal from the ethanol sensor into an ethanol reading. Basically it does away with the need to run an ethanol analyzer with your ethanol sensor. It’s really cool stuff. One of many reasons I felt going with ReFlex+ was the best option out there aside from stand alone.
@@midwestbmw1292 thanks for fast answer. Do you know or remember which Reflex wire taps into a pin on the DME harness? I would like to read ethanol content via MHD.
@@lionplanet3001 The ReFlex+ comes with a gray wire with a DME pin already attached to it. It’s in a separate ziplock bag marked flex fuel, or something like that. You’ll need to remove pin 16 on DME harness 6002 and plug that pin in its place. Then you use a provided wire tap to connect to the green wire on the Reflex harness. Essentially what it does is convert the ethanol sensor signal to hz so that it shows the ethanol percentage on MHD.
@@midwestbmw1292 thank you 🙏🏻
@@midwestbmw1292 Since reflex can read via canbus it is still necessary to remove that pin 16 form 6002 harness?
you should get some kind of mount while driving, camera in one hand while driving is no bueno.
Bro you are not wrong. The whole time I was filming I was saying to myself this is sketchy AF. Will have a solution for next video!
