afr correction reading incorrect in datalog
First time working with hptuners, I'm familiar with AEM, nistune and honda platforms, but this is for sure different. The problem I'm having is in the vcm scanner, my air fuel correction is saying -94%. On my ngk afx input in the scanner is reading correctly at around .93 lambda. So I'm only 7% rich rather than 94%. I'm assuming a channel is incorrect or wrong input to that afr correction histogram. Have any of you ran into this? Or know what I have set up incorrectly? Or perhaps I need to have lambda error as pid rather than a/f?

Ok, so I'm finding out I have to have common input to the channel. No lambda input into air fuel tables. Of course that makes sense. I have tried some of the commanded lambda and lambda error pid's that some people have put up, but neither of the two I tried worked with the 04 GTO that I'm working on. Is there any supported pid's for this ecm?

Put up a log so people can look and tell you what you are missing. Also put up your config.
