Question: 2nd ECU
Okay- I have posted this question in a few of the RPI threads without any answers so I am making a new thread.
Where can you buy a new ECU for our Z4 M Cars? I would do the ECU tune if I could have it done to a separate ECU and not the one I bought for my car. I had warranty problems on my last car I messed with the ECU with (also undetectable) and never want to go through that again. Especially when you consider the price of our engine and driveline...
Thanks!
