A 97 and a 95. I am converting the 95 to electric drive and have been pulling out bits. I'll be retaining the auto trans so am looking to understand how it is controlled. If I am lucky it will be entirely dependent on a speed input into an ECU and I will just need to replicate that feed. Am I lucky? Or will I need to fake other inputs as well? Other questions I have are just which is the speed or tacho input? Is it the sensor on the toothed gear at the front of the engine? Also is the black box that sits above the engine/manifold entirely engine performance and fuel related? If so I can cut it out, but if it feeds other useful things to the dashboard then it may be worth keeping and faking necessary inputs. Hoping someone can help or point me in the right direction.

While most of us aren't so intimate with the TCU for the ti, surely someone may be able to help. As far as the ECU, I'm thinking that is mainly engine control, but someone who has done an Auto o Manual swap may know better. Good luck with your project! __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

I'm guessing this is calculated from the crankshaft position sensor. I can mount that in an equivalent position in the new setup or produce an input using a separate bit of kit I also have, and bypass the DME. I'm guessing I need to do the former to ensure the input gets through to the Transmission Control Unit. I already know the speedo gets its input from the diff. I assume that doesn't go through the DME. I still haven't established whether the transmission needs any other inputs besides revs to change gears correctly. I assume it will also have some sort of kickdown input but I suspect it's not a good thing to open up full current for that purpose in an electric car.
