I want to build one of these ecus for my bmw z3 1.8 that came with a M43B18 engine but I swapped a M42B18 from a 1995 318is.
The thing is that I am using the wiring and ecu from the M43B18.
One more thing to take into consideration is that I am using a M44 throttle body because my M43 used the same idle valve (3 wire) as the M44 engines and to keep the same wiring and ecu I had to use the same idle valve. Here's a photo https://c1552172.ssl.cf0.rackcdn.com/20343_x450.webp
Which board should I build?
