Scott Posted September 11, 2012 Report Share Posted September 11, 2012 Hi Matthew, Adam is correct, there is currently a bug that occurs when a fuel pressure sensor is setup. However looking at your base-map you do not seem to have one setup. When you get a chance can you check what your wideband average reading is when this is happening (analog tab of run time values, accessed by pressing F12). Also can you tell me what AFR wideband 1 is reading (also on the analog tab) when the fault is happening. Cheers, Scott Quote Link to comment Share on other sites More sharing options...
