300+ HP

Ok kidding, but slight improved fuel economy, possibility to use megasquirt with the way the harness is designed, more aesthetically pleasing, chip availability, removes cold start valve, flywheel reference sensors, replaces broken connectors, gives an engine check light if you connect an additional wire.

Good afternoon, given the date, do I still qualify for this above?

My actual car is a US Spec manual 86 b34 running on Motronic 1. Since I tend to be somehow Moronic when it comes to electronics but thinking ahead anyway, I'd like to ask you:

-Is it possible to run a "Euro dirty engine" minus the 061 ECU and use your kit with the 1.3 you're selling?

-If I decide against building a Euro dirty engine but instead turbocharge my actual b34 will your kit still work?

-Lastly, what year and model does your kit comes from, in the event I need to replace something?

Thank you!

Jack

Yes.
The kit will work fine for the higher compression M30 you have, runs like a b35 with the same compression ratio.
If you turbo you WILL need to address the issue of standalone like MS, but the 1.3 makes it easier to use.
I use all non EML E32/E34 harnesses, you can call it a 1990 E34 535i M30 for your question.

Thank you for all your answers!
I don't have a Euro dirty engine yet but may convert my Us Spec B34 into one.
Please pm/email me or otherwise your Paypal account # for payment. Thank you once more.

if its going in an e28 then you dont have to do anything, you just plug the c103 together, its the white rectangle plug next to the ECU.

continue this in the b35 faq post so it dont become bloated. Check to see if the bulb exists in the back of the cluster first.
