[tuner23] Re: tuner issues - KAM what is actually remembered?

[dcolvin_xr4@yahoo.com]

I have to disagree with the hypothesis of Ford 2.3L Turbo EEC's KAM 
effecting engine fueling operation. Except for failure modes detected.

I believe that there is almost nothing "learned" by the Ford 2.3L 
Turbo EEC KAM. I think that most of the possible learning has been 
calibrated out.

During closed loop fuel operation the fuel is adjusted. However this 
adjustment should behave the same day after day. Nothing affecting
the fuel adjustment is "remembered".

An air meter offset term is learned but the maximum value that can be 
learned is 0.1 #/min of air flow.

On the other hand failure modes remembered in KAM could cause 
some interesting problems.
