Yes, we sourced the problem to a bad O2 unit that was giving us fits. The reason we needed it was that motor did not get enough dyno time and we were trying to jet the carb, what a nightmare. It poped our data box and tach, every time we went out it was something else, thats why there were wires everywhere tywraped to everything. Mixed into that was the seperate wiring harness for our lights for endurance racing. It is a seperate harness we built so that we could quickly fix lighting issues for VIR. At night that track is DARK,DARK,DARK. Did I say that it was dark therer at night!
