Fueling

Hey I have a question what am I looking at when trace mode is running?

Dunno, the wall, the floor, next door neighbours shagging in the backyard? Gotta be a bit more specific mate.

You mean you're tuning the speed density right? You've got air charge temp as the histo value. I'm just gonna assume some stuff now and say you want the actual afr as the histo value. This means you will need a dlp8 set up to input the afr into your log, then you need to select it as the histo value once you have the data, aka another log with the afr data in it.

It's just as easy to tune the fuel by doing some driving and looking at the afr line in the log.

No I know what the afr is im more wondering about while tracing is on and the numbers that come up when going through the rpm range

See where it says [ACT]- *F? That is the value in the histogram. You can change that when you set up the table trace. You choose the X axis value, the Y axis value and the histogram value. Generally you will choose rpm and some type of load reference for the axis and then populate the histogram with the value you want to see at those points. You can set up the rpm points in the axis to suit yourself or they will auto scale according to the min and max data in the log.
