I was just wondering how likely is it for me to have a bad ecu?? my engine and ecu are from jap. and i think that blitz tuned it there in jap and i think the ecu might be going dead so thats why my car is driving like crap everyonce in a while. is there a way to check the ecu???

Hey ive been told its very unlikely to have a bad ecu but can you tell me abit more about the car driving crap every once in a while, ours is the same, although at the moment its most of the time, sometimes it drives like a dream then all of a sudden the ecu light pops on and she throws up 3 or 4 codes, all of which we've been trying to sort out for ages.

And what do the codes tell you?

Bill,

usually turbo pressure sensor, 34 and 35 but often the knock sensor - which has been replaced and throttle position sensor

but they are so inconsistant....

it has gotten to the stage where she hardly goes well at all , at the moment even to get it to start we have to turn the distributor cap hard one way - which is in fact the opposite way to which it was when we first bought the car

no codes just the car will sometimes have a really bad miss, and others it will be fine. My Dad's Porsche had the same problem and it was a bad ecu. he then had it rebuilt and now it runs fine. I'm just trying to figure out what it could be.
