Kam's, fuel trim on and off throttle?

zenboy99 · Apr 11, 2006

I've been noticing something in my datalogs lately. Light throttle when my MAF reads 1.2 volts my kam's read ~1.02, but off the throttle at 1.2 volts they read ~1.10.

I'm still reading closed loop, and I'm not in lean-decel. At least I think I'm not since the closed loop light is on and the kam values are changing on the tweecer.

Any thoughts? How is this effecting the datalog as its calced in EEC analyzer. Is the computer recognizing what the tps is reading?

Seems like I remember someone saying the CL light is not to be trusted when using V1.30 but again, I can't be certain.

What kind of value do you see in the raw data?

As for the k's reading different at the same mafv ..............

You have several fuel shutoff things you can play with.

You may have to tune for a happy medium with your maf points at and around 1.2 volts.

I fooled around with a nasty lean spike at low maf voltage points for a good while and finally went to forced OL idle.
