Scott Posted September 11, 2012 Report 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
Matthew Black Posted September 11, 2012 Author Report Posted September 11, 2012 ok in the car now wideband average value is 0 wideband 1 is reading 16-17 afr when closed loop is on at -15% trim Quote
Matthew Black Posted September 11, 2012 Author Report Posted September 11, 2012 FIXED IT did a firmware update on ecu to 4.9.3 and now average wideband is same or close to wideband 1 and closed loop works fine THANKS Quote
Matthew Black Posted September 11, 2012 Author Report Posted September 11, 2012 firmware was 4.7.1 Quote
Scott Posted September 11, 2012 Report Posted September 11, 2012 Good news, pleased to hear you have it all sorted Quote
