i have followed your progress on the crossfire forum and think its awesome! the ecu has always been the bugger for these cars has had many a mechanic reachin for a hammer!! so when does the amg blower go on?
I posted on here because what I did is exactly what a guy with a SLK 170 would do to put a V8 in. Brabus offered this swap for the R170 and offered the exact same swap for the Crossfire under the Startech name.
the hardest part of the swap to figure out was the electronics. But if you start with a ECU from a wrecked car that has a glitch things really get tough! since we managed to get all the computers happy with each other and all the correct coding into the ECU and the anti-theft system all happy, I am confident that this is a good approach to a swap. We are hoping that with a replacemnt ECU we will get the starter signal through the ECU to work. right now the engine runs fine but we have to turn the key on and manually ground the starter therby bypassing this function that the ECU is supposed to perform. We know we don't have an anti-theft/Imobilization problem because we can see this in the STAR Diagnostic system.
My goal is to have the running as though it came stock with a V8 and runs and drives OEM. Once I acheive that I will start normal mods to make the V8 really run. Under consideration is cams/headers, and forced induction. the AMG supercharger would look and run great but a rear mounted Squires single or dual turbo system would do more for the car. The supercharger would be great for instant low end torque but with the V8 in such a small car, low end torque really isn't an issue. Having the top end of the turbo might be better. the only forced induction that will fit in the engine compartment is the AMG supercharger. There is no room for a turbo or belt driven supercharger.
