Do you turbo guys with the JWT ecus still have a check engine light? I have the following codes and was wondering if everyone else had them too...
34-knock sensor
76-fuel injection problem, running too lean/too rich
77-rear O2 sensor
I have a test pipe so I'm pretty sure that's the reason for the rear O2 error code. I'm guessing the knock sensor might be from the cams. And the running too rich condition is just from boosting. Anyone else?

Hi, I run the JWT ECU 3bar no codes here.

It sounds like you have disconected your O2 sensor, I think that is why you are getting the codes.

the knock sensor one is a bit odd.... I've gotten the 76 before. turned out i had to recalibrate the tps.

Anyone else have any suggestions?

when i had my setup for a short period of time i got the same thing. i was running bb setup with jwt ecu, but i only got the knock sensor code once and i reset the ecu and it never came up again.

knock sensor?

we don't need no stinkin' knock sensor

:p

I just pulled a 34 (knock sensor) and a 95 (crank pos. Fidanza flywheel)
