Hi everyone !!! I have a 1997 Impreza wrx import and I’ve been told I have a aftermarket ecu can any help me identify what ecu this might be? Many thanks 

Can you take the top of the ECU case off , as it might have a esl daughter board ,simtek or other mapable chip inside .

Do you have a boost gauge if so what is the max bar of boost ?

Thanks for reply @savage bulldogsI will over the next couple of days get the lid off the ecu and get back to you with a pic or two!! I’m sure boost gauge goes a tad over 1bar but def hits 1.0bar I’ll have to take a look ! I was told it was 335bhp
