Hmm thats interesting.


The ecu can work out misfire by measuring the acceleration of the crankshaft after each cylinder fires, no acceleration it assumes misfire.


Im wondering how it would work out the learning for individual cylinder port and direct injectors since it only has one 02 sensor measuring comosite of all cylinders on a stock header but on many aftermarket its in one cylinder runner.

The obvious one would be by injector ratio split

How would ecu know individual cylinder correction's with only one AFR sensor , could understand if it had one per cylinder

It's the LTFT RPM ranges, not cylinder.

There's really not a MAF rescale out here for the injen short ram intake anywhere or a directory on the front page of this guide? This VGI tool is being difficult. I can't even copy/paste the results into RomRaider from the logs.

EDIT:

MAF scales for INJEN and TRD image attached but it'd probably be quicker to use the VGI tool than to hand jam these numbers. Can't attach excel files
