Re: Motronic 1.3 conversion for M30B34
I'm late to the party, but will be doing a 1.3 swap with Miller MAF on my B34 - can I still use my JB Racing aluminum flywheel?

Re: Motronic 1.3 conversion for M30B34
*SOLD*
Have a new kit with brand new bosch original oxygen sensor (correct screw on for the b35), all sheathing and tape removed. Rewrapped in super 33 3M tape, removed old pick style connectors and soldered quick release connectors, entire upper harness has been rewrapped. You only need to connect the c103 on your own car (tach and fuel econometer). Everything else still comes with it like in the first post otherwise.
415 for this one, a lot of time has went into it and new o2 sensor.

Re: Motronic 1.3 conversion for M30B34

Re: Motronic 1.3 conversion for M30B34
Hi there! Bimmerguy - you and I had been chatting over PM and all of a sudden it seems that the forum no longer allows me to compose and send DM's. Last note I left was that I would check my fuse box connector, it looks to be circular so should fit. Just need to be able to contact you so that I can get this M30 in and running . Sorry in advance for my ignorance wrt the forum nerfing me haha... thanks friend

Re: Motronic 1.3 conversion for M30B34
check to see if you accidentally blacklisted me (if the function allows via private message). If you cant figure it out or whatnot email me jspec20, the last part at hotmail
Re: Motronic 1.3 conversion for M30B34
Got it. Checked and doesn’t look like it. Won’t let me PM anyone on here for some reason. I’ll shoot you a msg in the am. Thanks a ton my friend.

Question for Bimmerguy2002, this may have been answered before,
but do your conversion kits work with EH cars?
Thanks

Re: Motronic 1.3 conversion for M30B34
If you're referring to the automatic trans wiring, no it doesn't. It is separate and you need to do that part of it yourself. It will work, but you will be in limp mode all the time. The best scenario is find someone parting an early car and grab the non-EH trans out of it.

Re: Motronic 1.3 conversion for M30B34
Sorry didnt see the reply, buzzbomb got it right, the correct answer.
Re: Motronic 1.3 conversion for M30B34
BuzzBomb can correct me as I believe he knows how to do this conversion, but the 1.3 conversion with an EH Auto is possible, and this kit gets you part way there. The transmission control unit (TCU) needs input from an automatic TPS, engine speed output, and fuel rate output to work properly (the TCU also sends a shift signal to Motronic to retard timing on shifts). The primary modifications required involve tying the TPS signal from the new harness into the C238 plug alongside the glovebox. Studying the e28 ETM (page 2460-3) and an '88 635CSI ETM (page 2460-2) will give you a good idea of what you need to do.
Re: Motronic 1.3 conversion for M30B34
You are not wrong, as long as you’re using an automatic harness. All the signals you mentioned are included in the harness so you don’t need to add them. You just need to make a few connections between the e28 trans ecu and the 179. I told people back in the faq that I would offer the pin outs to whoever asked for them.

You can click the name but i think you have to have a certain amount of posts (dont remember the rules regarding new members/members with low post count).Bronzit5er wrote: ↑Oct 18, 2023 4:22 PM Hello, very interested in a 1.3 kit for my 1986 535i that I just manual swapped.
