Idle afr

Post by Boosted_red_em1 » Wed Jun 19, 2019 3:00 am

Why is it that while the car is warmed up to operating temp, while data logging in real time, I set the idle and get it to 14.7 and it will be fine. I make sure I save and even hit the upload button a couple of times just to be sure. But the next day I’ll come out and start her up and when she’s warm, it’ll be rich as I never touched it. Not sure if I’m doing something wrong or what, but it’s annoying to constantly have to mess with the idle af every time I go and drive it seems.

What is the serial number that is on the s300 board inside the ECU?

From Help, About, what is the version of software you are using?
