i am looking at numerous WB logs of AE into PE event. seems my current FP has solved the lean(13.3) PE condition but is over the edge rich on AE. I am seeing AE spike downward to 11.00/1 going richer at 13.00/1 and then PE comes in dropping A/F to around 12.4/1.

TPS is 100% for 5 seconds with rpms over 5000. 2nd gear of 5.

so i can bring in PE sooner than 50% TPS but would prefer to sacrifice some AM to allow event to last longer. i believe it is available. how to do?

 

To increase the duration of AE, lower the values in these 2 tables:

AE - MAP Filter
AE - TPS Filter

This will at the same time increase the volume of AE. So you will probably need to reduce the AE PW tables a little.

Note the above 2 tables are based on engine coolant temperature (CTS). Make the changes at those areas that correspond to the CTS.

For other stock TBI ECMs, the '747 has both of those tables. And the '8746 only has the one for the MAP.
