LS2 E40 2 Bar Custom OS

[vetteboy2k]

Looking to begin 2 Bar SD tuning on an E40 Controller. I see how the upgrade OS works and have done that on a stock file to look through although some questions arise b/c there are no EFILive Custom Calibration tables.

Has anyone played with 2Bar OS on an E40 Controller?

I see there is no boost timing tables, no commanded fueling based on KPA/RPM, and no IAT VE multiplier.

I do see a boosted VE but thats about it.

Any direction on where to go to begin. Are LTFT and SFTF still in place?

:cheers:

Yeah, it really just added the boost VE table, the ECM thankfully handles boost as is, though, there was no boost table VE as such.
We are never converted anything but the GENIII PCM O.S's to run the load based AFR table.

Cheers,

So to run 2 Bar for boosted applications you leave the MAF in place and mainly just need to tune the ve, boosted ve, and scale the MAF for the increased airflow?
