Hey guys, I've got a pretty basic question (at least I think it is)... I've got a SBF single turbo car with the classic FAST system. I made a cam change and now the issue I am having is with the base fuel curve. The graph is map vs rpm. With the car idling the green bubble in planted on the very bottom row of the graph. It moves side to side with engine rpm change but it will not move up and down (increase/decrease in MAP Kpa). The map sensor is reading 50-60 kpa of pressure at idle. So the bubble should be on the 3rd or 4th row and not buried on the bottom row. The car stumbles on initial throttle and even dies (too much fuel). I try to take fuel out on the base fuel curve but it has NO effect on the issue. If I rev it up and keep it at a constant rpm (2000 or 2500) it starts popping through the exhaust and the green bubble is still pegged on the bottom row. Any advice or tips you guys could give me would be greatly appreciated. I'm at a loss on this one.
