it could be your iac, isc or whatever the hell its called. I used a cali spec ecu on my fed spec car without issue. I guess it is possible that the opposite wouldn't work.

I understand where your coming from, but the car ran fine before this. no sputtering, hesitation powerloss @ all, then the ecu died and sat for 2-3 months. so i dont see how anything could have gone wrong.

Ah, but in order to troubleshoot you have to lock out all possibilities to narrow your search. What's 45 min compared to knowing 100% it's one less thing.

knida off topic..but did you replace your plugs/ wires?

I just got a PM from Gabber and he said that prior to deciding to part his car he had the ECU tested by a mitsu tech to rule it out as a problem.

I replaced my CAli spec car with a fed ECU. Same thing happened. From what I gathered the only difference between the 2 is the EGR is absent on the FED models. After installing the FED computer the car was only running about 5lbs of boost no other changes. It would sputter and kick around. I installed a MBC and checked out the ECS and found the ecu was bad back there too..pulled it and it the car runs great again (except for the squishy suspension)
