Hello everyone,
I received an MR2 with a 4G63 engine running a Haltech Platinum Sport 1000 ECU, amazing car and owner.
It didn't have any idle control, after some diagnosing, i saw the the Stepper IC on the Haltech Platinum Sport 1000 ECU has exploded. reverse engineering the pins led me to believe that it might be an MC3479P. can anyone confirm ?
