I was able to figure this out by tuning the MAF correctly and also updating the AFR table logic.
For the MAF I was not properly understanding when to raise and lower flow values in the table. If the LTFT + STFT >> -3 you can increase the values around that voltage range. Similarly if LTFT + STFT ...

Re: Air Charge Limit ignored?
Alright, I guess I can scrap it and start again, I mostly was just trying to eliminate the high positive trim around 4V. Honestly it didn't make sense since the AFR would go 11's when the pump hit 100%...

Re: Air Charge Limit ignored?
Here is the calibration I used for the last data log. I had already unchecked the mod to allow greater than 250% AIRC.
4_28 calibration.fpcal
You can see I increased the flow on the MAF for >4V a pretty large amount.

Re: Air Charge Limit ignored?
I am at a loss. I have lowered the AIRC limit to around 225% but I got a spike of 312% last run. Also from tuning the intake, the flow rates seem impossible now (but my AFM.v to STFT doesn't look too horrible) since based on my g/s rates I would be making ~460HP and 490FtLbs with a stock fuel pump ...

Ok the boost by ethanol does not seem to be the culprit. I still hit 268% on a short pull after I limited that table to 235%. This run was also much better as far as LTFT I mapped the intake a little better and it is now at -4% LTFT so I don't believe that is the ...

Re: Air Charge Limit ignored?
Yeah good point, that started with the new MAF as well. I figured it was because the intake still needed to be mapped properly but not sure why it is so rich...

Re: Air Charge Limit ignored?
Thanks will do, as a side note this started happening after I installed the hondata MAF 500 sensor.

Air Charge Limit ignored?
I am getting 250-272% AIRC from around 4500-5100 RPM. My Calibration is set for a maximum air charge limit of 235% so this is maxing out my fuel pump to 100% sometimes. I am not sure what settings can override those limits. Does anybody have any idea? Thanks!
