Engine management light?!
Any help would be appreciated.
Ok Brought my scoobie last year, but a Full Decat on her, have taken that off now due to selling the car, but my engine management light is still on. There is no running problems with the car, its as good as before but not sure why the light is still on?!
Its a 54plate WRX.
Any help?!
Regards

No.
MAF = Mass Air Flow. Tells the ECU haow much fuel to inject for any given airflow density.
It's fitted btween airbox and turbo intake hose. it has an electrical connector to it (for the ECU to read it's output voltages).

see if you can find anyone local with a tactrix cable, you can read and clear the codes with that, or best bet get the ecu reset to let it relearn all values due to going back to standard,
