Can anybody help me please . I have a del sol with a turbo and tuned on crome i did it all myself and i noticed that the Q31 have burned the car is running well, the only difference is that the RPM limit is 8500 now and it was 9200 and i think thats it.. no other difference. Do you guys know that this Q31 is for and why it burned and what kind if it so i can buy it and change it . Thanks a lot

 

1. Check your wiring to your intake air temperature sensor.
2. Check the IAT sensor as it is probably melted.
3. Remove q31 from the ecu.
4. Datalog & make sure your getting proper IAT (intake air temp) readings.
