I was looking through the new released tunes and looking at hondata fuel system with efr turbo map. It doesn’t have a corrected MAF scaling. Only the older full race tunes have a scaled MAF for the 3.5 inch MAF housing. I did notice the fuel trim offset at almost 20 percent. Same goes for other hondata fuel system tunes.
not correcting MAF scaling when increasing MAF housing can cause lean afr.
Also the new VE correction tables are the same on all tunes so that won’t compensate for MAF housing. I’m going to guess this was an over sight.
It helps get injectors inline but I’d prefer to see injector scaling. It would be nice to also see suggestive correction available on VE tables. This could speed up the process drastically.
Or having a 3D datalog graph would be just as good.
this way you can do something like aircharge vs St strim vs rpm.
