Impreza Posted March 15, 2016 Share Posted March 15, 2016 Does anybody no what this ECU is? I have a 92 classic gc8 and it has two ecu's but only one plugged in?, I've been told it's mappable by my friend I bought it of but don't trust him.

stants Posted March 15, 2016 Share Posted March 15, 2016 Is that the 2nd one or the one that's on now ? Have you tried googling or ringing the people who's sticker is on the front ? Only other alternative is to open it up and see if it has an esl board inside 1 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted March 15, 2016 Share Posted March 15, 2016 As above would be my first port of call. It does say "jap stage 2 chip" which makes me think it's more likely to be a generic "chip" (like a mines ecu) which just raises the boost and has more advanced timing ,Rather than being re mappable which lets a mapper adjust the map live . If the car seems to be running ok get it on a dyno to make sure it's fuelling is correct ,as it's only about £50 for a power run and could save you a lot money in the long run . If it's not broke .....upgrade it 😊 1 Quote Link to comment Share on other sites More sharing options...
