There was a option I used to used in this menu that is no longer here.... similar to afr's..... where did it go???? It disappeared since I updated the to the new software.

Try
File > Configuration > User Mode: Expert (bottom right of window)

And then don't ask why the ECU does not do actual AFRs that you set in the fuel map (too many people ask me this...)

Actually did not have a problem as far as that was concerned Matt...... But....... I don't see why their isn't a way to be able to calibrate it to the car..... in a options menu maybe... get it some what close.... it does not seem impossible.

I will take a peek as soon as I get home thanks!!!

Dj you are right on the money worked like a charm and I'm back in business .....

Think of the injection time = TP (MAF/RPM*K) x TIM x trims x enrichment x fuel map value + latency

AFR is a result of injected fuel and airflow.

Given that the fuel map value is only part of the equation it is not strictly possible to specify the actual AFR without an extra trim map against wideband feedback

So the fuel map values are effectively a pulsewidth multiplier rather than the resulting AFRs

Ok, Thanks matt.....
