Hey guy, I just picked up a 99 spyder eclipse 2.0 turbocharged AWD. The ECU/ECM inside the car is MD359402 and I read it was for FWD then I read MD359403 and it was for AWD. Can I run both on the car if the previous owner had used 02 on it? I don’t understand the difference
 
the MD359402 came in all 99 spyder GST's, which is what your car was before some converted it to AWD.
your good with the 402

i have heard that the 402 have a governor but the 403 don't.
Thats the only difference i know of
