So. My car has been sitting at my tuner for over a week now trying to get this problem sorted.
Car: 2002 WRX Sedan
Current mods that could affect the engine:
Grimmspeed Up Pipe
ACT Streetlite flywheel
Tomei Expreme Ti catback (installed after trouble started though)
AEM CAI (came on car)
Blitz BOV (came on car)
Problem: ECU cannot be flashed
Symptoms:
The car starts and runs just fine, about 95% of the time. Sometimes it will stall when coming to a stop and not want to restart. If I let it sit for a few minutes, it restarts and drives normally. Last time, I didn't have time to sit so I did a roll start down a hill and it hasn't done it to me again since (about 300 miles ago)
CEL is on, Catalytic converter performance out of spec or something like that
CEL cannot be cleared
ECU cannot be flashed
The shop has checked all the wiring between the OBDII port and the ECU and they found one wire that was "off". They fixed that, and the ECU still won't flash or communicate with his computer. They've been tuning other cars in between working on mine, so it's not their computer or cables.
I brought the car in for the fuel line recall at a dealership in early March. They did the recall and the car wouldn't start back up. They replaced the ECU and magically the car started. I brought the car (with a new ECU) back to my tuner shop to clear a CEL that came on because of the lack of EGT on the new up pipe. They couldn't clear the CEL now. Brought the car back to the dealership, they somehow cleared the CEL, it stayed off for a week and has since come back on.
I talked to the shop this morning, and now we're to the point where they can get into OBDII on the car, they can even Datalog the car, he just can't flash the damn maps.
The last trick they have up their sleeve to get this sorted out is to jump the pins right at the ECU and see if that works.
I NEED to get this ECU flashed because I have parts sitting at the shop waiting to go on. They can't go on until the ECU can be flashed though since they require a tune.
Anybody have any thoughts they'd like to throw in here? Anyone with a similar problem in the past?
$1600 for a Hyrda is not in the cards at this time.
