essb00 Posted October 13, 2020 Report Share Posted October 13, 2020 (edited) Good day, It seems that the recommendation -4% per 10°C rise from 20°C is too much as IAT temp in city traffic of tropical regions easily shoots upwards of 70°C. My VE table getting more than 100 even at partial throttle, and CLL keeps getting max clamp not reaching target AFR. What values should I instead use in IAT fuel trim table?

Adamw Posted October 13, 2020 Report Share Posted October 13, 2020 IAT Fuel correction should be turned off for modelled fuel equation. The air density change due to charge temperature is already taken care of in the fuel model. essb00 1 Quote Link to comment Share on other sites More sharing options...
