I have the Cobra dragsters. I installed my Fi200r last night. Andre @ Cobra told me to unplug my O2 sensor and plug up all the connections. I haven't made any adjustments to the processor yet. I'm still getting the backfire. The instructions say for the popping on trailing throttle to adjust the green (far left pot). Has anyone done this yet and if so did it take the backfiring and popping out?
