Been having a couple issues with idle changing af alot mostly leaning out. i dont mess with ect or iat corrections. I changed injector voltage compensation tables and no help. it will sit at 14.7 perfect at idle then after some time lean out to 15.5 to 15.8 sometimes.

Also i took this log today and added 3% then clicked ctrl+L and still said 3% off. it never changed and yes real time update is selected.

Having issues and have 2 cars to get to a race this Sunday. any help appreciated.

Car is a crx, PLX M300TE wideband on D10, b16 swap crower stage 2 1/4 cams valvetrain, victor x im, 6xmm throttle body. putting pump and injectors in this week.

What do you mean by a crx wideband?

You have to post datalogs showing it normal and then it not normal. In the datalogs you have posted, one is idling, and the other is not. There is nothing for comparison

I was reviewing the vtec 2 log and noticed the iat's were high 148 degrees and that's from 1,000 - 8,000rpm. I'm wandering if its the iat fuel trim? I will log this car when I get home for a better log for you to see. Also will log the others car this Saturday. Both cars have Victor x manifolds and Hondata I'm gaskets. Is there any issue with heatsoaking iats on these manifolds even wile driving.
