I just picked up a K8 ecu. I wanted to compare the differences between the K8/Je50 and Kl55/Kl01(that's on it now). I'm running a 95 curved neck Millenia engine in my 93 GS, so having to compare all these combos to match the extra sensors and not give me a ton of codes is rough. I opened the ecu up and saw writing on one of the chips. Could this possibly be a chipped ecu? Or just how it is?
