duncan351 Posted December 6, 2019 Report Share Posted December 6, 2019 After start up on cold starts the engine is getting too much fuel making for a very rough idle during the warm period Once it gets to about 140 or so it clears up. I have zero'd out the cells in the Warm up enrichment tables. It would have been nice if they could go negative basically making a ECT fuel trim but this table just doesn't have enough control. Any suggestions? Update: I just enabled the 5D fuel table and selected always on with my Axis's ECT and TP Main. From there I will pull fuel with end the ECT temps and see if this will work properly but I would think it should. Gonna try this tomorrow morning when I wake up. Am I on the right track?

JMP Posted December 6, 2019 Report Share Posted December 6, 2019 are you working in Modeled fuel mode? If so, have you done much with the charge temp table Quote Link to comment Share on other sites More sharing options...

JMP Posted December 6, 2019 Report Share Posted December 6, 2019 I'd be reviewing the charge temp table for sure Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted December 6, 2019 Report Share Posted December 6, 2019 Too high of a dead time can have the same issue. Do you have the correct injector data. Quote Link to comment Share on other sites More sharing options...
mapper Posted December 7, 2019 Report Share Posted December 7, 2019 I agree ETC table should allow also negative corrections, for "quick and dirty" adjustments. Sometimes you can tune charge temp correction perfect for normal operation temps (60-110 degree coolant temp and 0-80deg IAT) and when you finished with the whole tune, you see next day that the cold start is to rich. Means you need negative ECT trims. Quote Link to comment Share on other sites More sharing options...
motomattx Posted December 13, 2019 Report Share Posted December 13, 2019 An ect trim table would be a beautiful thing. Quote Link to comment Share on other sites More sharing options...
