[QUOTE="69b302, post: 16218564, member: 52691"] I beleive the PID is just "open loop flag". What year GT500 do you have? The open/close loop tuning does not exist in the newer models(2011+ IIRC). The wideband is most likely reading lamba, and then converting to AFR, so is baiscally showing gas AFRs for ethonal fuel. I just let my wideband display lamba, as when using different fuels, lamba is consistent. [/QUOTE]
