Hey if you have a JWT ECU can you still read codes from doing the diagnostic feature. Also if you do the diagnostic reset by accessing the little screw on the side do you risk resetting the reprogrammed circuits done by JWT?

 

1. Yes all the time.
2. I dont think it would effect any of the programing done by JWT.

 

Their programming is in some form of PROM, you can't reset it to stock specs just by 'resetting' the ECU.
