cant get idle and low map cruise below .800 O2 volts.
I had my car tuned pretty good before I installed the flyback board because of a FET failure. After installing the flyback board my car runs rich at idle and low load cruise. It's as if the injector pulses cant get short enough. Is there an easy fix for this problem. I'm running a 2.2 litre turbo 4 cylinder. It had 33lb/Hr injectors. It is basically a stock intercooler chrysler turbo setup. I dont run a CAT so I'm being gassed to death when the car idles because it is so rich even when the injector pulse width is 1.5 ms according to MT
