right so i got this ecu from bb and when i had it rr the guy said its too rich (too much fuel intake) he said this is due to the ecu bein wrong. anyone else had a problem??
as far as i no mate, other ppls have been fine but not had them rolling roaded. i believe james had his done and said it was running spot on! good gains.
Thye ECU stays on closed loop with the lambda most of the time which means it should run a good AFR.
If i remember correctly, your the guy that came down to us and we didnt want to fit the ECU due to cam and follower noises?? If so did you get this rectified?? May be the problem if there is one or may be a sensor problem, As the guys have said give us a call. Unless we hear about these things, theres not much we can do. If the car is running rich im confident its not the ECU. (Give us a bell)
by the way Eugene, just thinking about it in bed last night, I had a sensor go about 18 months ago which led to mine overfuelling, I think (IIRC) it was the MAF sensor (airflow).
