R24 Posted September 21, 2018 Report Share Posted September 21, 2018 Hi, In the modelled fuel mood, the iat fuel correction is not used due to ecu uses the gas law calculation hence using the charge temp table. Do i need to turn off the iat ignition trim table too? I noticed it was turned on. Regards, Ragu Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 22, 2018 Report Share Posted September 22, 2018 The charge temp table is used to calculate air mass for the fuel equation. You would usually still want/need the IAT ignition trim table active - at least in a knock limited turbo car. Quote Link to comment Share on other sites More sharing options...

There are few things I need clarification on the settings. Is it normal to enter -ve values in the cells lower than 100°C? Mine was set with -ve values starting from 40°C.

Mine was set with -ve values starting from 40°C. It would be normal to have negative values for temperatures above whatever temperature was present when the ignition table was mapped.
