M30 OEM Turbo project

Anyone else have this problem? My AT TPS sits much "higher" than the MT TPS, due to the larger plug. Even with the hood insulation removed, it presses against the underside of the hood and it made a dent :curse:

Solved (most) of my MS issues!

I couldn't get the damn thing to idle, it would just hunt and die. I finally started messing around the the ICV hertz, and eventually found a setting (187Hz I think?) that made it idle. It's a bit high at 900rpm but it's better than 0rpm :)

I also found out the issue with my tach being dead and TunerStudio not recognizing my AFR signal. When I tapped into the ECU harness to run the AFR signal, I accidently pulled up a wiring diagram for an m42 car , SO I ended up cutting the tach wire and trying to feed the LC2 signal in to it :rofl:. Now that I've corrected that, I have a working tach and working AFR reading. Hooray! Next step: test drive :mrgreen:

that's great! did you end up doing anything with your auto TPS?

It works perfectly but still hits the hood. Not sure what I'll do yet.

Hopefully this weekend!

Ya I know :sad: When I wired in these HIDs/Euro light slike 7 years ago I didn't realize you could buy them. But since I literally never drive this care in the rain, and that the fugly wires are covered by the black trim panels, I never bothered to fix them. Maybe if I get bored this summer :)

You're attitude here is simply unacceptable! fix those things :hitler: lol

If i was in your position, i would get the wires coming out of the TPS at a 90 degree angle without the connector and use a 90 degree heat shrink or boot to make it look factory-ish.

Just wondering what are you using for a motor mounts? Maybe your motor mounts are a little taller raising your engine causing it to hit the hood? Im using the revshift ones with no issues.

I have the urethane bushings from... I don't remember who exactly. He's here on the forums and sells them, but his name escapes me at the moment. Probably the best bet is for me to cut off the factory plug and try to install some little 90* connectors of some sort, make an ultra-low-profile plug.

Those g-man mounts? But yea what you stated will be the easiest fix

[CorvallisBMW]

That's it, G-man The Visionary. Really awesome mounts with zero NVH increase.

[car_gal_jenni]

what an awesome build! i just got done reading the whole thread & this is just intense. i don't think i'll ever do anything quite this crazy with my e30, but i have got to give you props on your thoroughness & oem look!!

[Bearmw]

I give you props man. Your M30 swap is unique and well thought out. We all stand to gain from your experiment. I bet it vwill rip.
