Wildt267 Posted October 17, 2023 Report Share Posted October 17, 2023 Link 104x running modeled fuel. I noticed i have iat mode set to on. The help file indicates that all applications should be ruining iat correction. But isn't that already baked into the modeled fuel equation? Am i basically doubling up on fuel correction?

Vaughan Posted October 17, 2023 Report Share Posted October 17, 2023 The charge temperature correction takes care of both the IAT Correction and the warmup correction so neither of those are required when using modeled fuel mode or when using traditional fuel mode with charge temp correction turned on.

Wildt267 Posted October 18, 2023 Author Report Share Posted October 18, 2023 If i have relocated the ait from the pre turbo maf sensor to the intake manifold you would expect the charge temp correction table would be significantly less than the basemap values yes?

Adamw Posted October 18, 2023 Report Share Posted October 18, 2023 Take a look at the WRX11 base map, the charge temp table in that was reasonably well calibrated, it was a JDM sti with the air temp sensor in the manifold next to the throttle body.

Just to be sure - when you say warmup correction you don't mean warmup enrichment ? Quote Link to comment Share on other sites More sharing options...

Yes I do mean the Warm Up Enrichment table in the cold start menu, the Charge temp table corrects for both ECT and IAT. Quote Link to comment Share on other sites More sharing options...

I know this is someone else's thread but I'm using both the warmup enrichment table and the chart temp correction table in all my maps (3 cars) but not the IAT correction table - the way it reads, it sounds like I shouldn't be using the warmup enrichment table either... I might zero it out and see how it starts up cold.. please forgive me if I'm getting the wrong end of the stick. Quote Link to comment Share on other sites More sharing options...

You will need to adjust the charge temp table after zeroing the warmup enrichment to account for that extra fuel no longer being present. atlex 1 Quote Link to comment Share on other sites More sharing options...
