I have a W6 22611 AA810 A18-000 RJB ECU in MY94 WRX. Is there anyway I can tell if the ECU has been mapped, or upgraded in anyway?

Thanks

 

think thats just a standard ECU

the only way you can tell if it has been upgraded is if there is a chip been fitted in the EPROM socket. Also there is a J1 resistor which would need to be Cut to allow the chip to work.

have a look at the fitting guide on www.scoobyecu.co.uk you will see where to find the jumper and stuff
