The target afr map is rpms vs engine load... right? so when you log via durametric you look at the same values and see where the afrs are too lean or rich... then you go back to a map where you correct the afrs per the logs... and thats it... but this is just the target map not hte fuel correction map... I just wanted to show you guys how it all works together....

the second is a ignition map... same thing... those values are actual timing numbers...

I dont have the map your asking... sorry...

 

Good ol WinOLS!

 

Thanks, Mark.

Beyond my knowledge level. I think that you are saying that the wideband O2 sensor reports the AFR, then the ECU compares that value to the target for that rpm and then corrects fueling to get to the target value. Is that the control strategy?

That's basically correct. Most of them are written rpms vs. Engine load

A few like the boost maps are rpms vs. Engine temperature.
