Think of the AE table like an accelerator pump on a carb, the only time it adds fuel is as you apply throttle. The DE removes fuel when you close the throttle.
Don't zero out while tuning and leave them enabled once done. I suggested zeroing out and testing to see if you still see the 11.4. I suspect you will.
I don't remember if you are using Target Tune or not. If not another experiment would be to reduce your ve tables by 15% in the 95 & 100 tps columns and checking
your afrs again. To be clear it's wot you're seeing the 11.4 afrs?

I and using my wide band O2 sensors provided with my Target Tune for feedback on actuals AFR's
Its in my sig the 2013 110" 217 ccp.
I get that the AE acts as an accelerator pump as in on a carb but the AFR's never come back up to target AFR's as load decreases and rpm goes up.

Ok but remember Target Tune needs a pretty accurate set of ve tables in the map to have a chance to work. It doesn't remember what it did the last
time it entered a cell. It has to relearn every time. As a test I would reduce those ve numbers 10-15% and do a data run to see the difference. You should
be safe to do that as rich as you're seeing.

A better terminology.
So in my simple mind the EFI program goes through the data and works out what the width should be. It finally reads the value in this table and does the maths to create the final value.

The ECM and PV look at several sensors and tables to calculate the proper pulse width to achieve the proper AFR's.

post up your desired AFR table......
i'm wondering if it wont be able to get where you want it at such a richer than norm desired afr of 13.0-13.9 through the whole table,,,,,will it lock into closed loop with that rich a desired afr table?
