I've attempted to put an Evo 8 ECU (USDM) into my '99 eclipse gsx. Everything is working perfect, with the exception of the climate controls. I get no air and no heat when I turn the fans up (although the A/C condensor sounds like it is turning on).
Based on what I've read/found online, here's the pinouts for the two ECUs, followed by the pins I swapped/changed. Any help with this would be GREATLY appreciated, as I'd hate to ditch this project just because I can't get the climate controls to work.
The color-coated pins indicate those that I swapped/changed/disconnected:
Swapped pins 8 and 22
Connected pin 31 from the EVO ECU to pin 34 on the vehicle wiring for the Eclipse
Connected pin 31 from the EVO ECU to pin 20 on the vehicle wiring for the eclipse
Connected pin 32 from the EVO ECU to pin 21 on the vehicle wiring for the eclipse
Disconnected pin 87
