View Full Version : engine leans out when open loop fuel takes over

The map I'm running has worked pretty well. Usually on the closed to open loop fuel crossover, the engine richens up a bit which is ok. Recently when it crosses over the car goes lean, hesitates, sputters, maybe even misses. I updated my software from 5.0 to 5.8 thinking maybe my program had a bug or maybe crapping out. No luck. I took a log just revvin it in the driveway. It occurs this way as well. My crossover point is at 25% TPS. Cruising around town seems fine, just until I hit open loop.
