IAT Fuel Trim -4% per 10°C

Recommended Posts

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?

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.



Thanks... :) That's why....
I have now turned off IAT Fuel Correction.
