PIDs to Log Idle STFT

[tinindian]

In OLSD, with B4108 (STFT Idle) enabled what PID should I log to see what the trims are doing? Would it be SAE.SHRTFT1/2 or are there others specific to idle trim?

did you look at GM.IAC_STD_DMA, GM.IAC_STDAC_DMA, GM.IAC_STPN_DMA, and GM.IAC_STPNAC_DMA? If your choose the Idle PIDs from the system pull down in the scan tool, you should see long term and short term correction.

I haven't looked at those, but they are for the air control (IAC), correct? I was looking for a fuel control trim PID.

ah gotcha, then yes SAE.SHRTFT1/2 are the only ones that I know of.
