15 Hellcat limp mode at 5300rpm, DTCs, 19.5psi E85 ID1300
I ran into an weird limp mode situation while tuning a Challenger Hellcat auto trans.
Car has ID1300, e85, upper and lower pulleys, woody intake and cat delete.
Lamda is ~.85-.86 so far, trims at WOT are ~+3% timing hasnt been altered yet, airflow thresholds have been raised. I have adjusted both maf and ve tables playing with no results. I have played with the pcms calculation of actual torque, nothing. There maybe something im over looking.
I go WOT from 2500 or 3000 and when i reach 5300rpm the throttle cuts, both 5th and 6th.
I have seen the following DTCs while inhave been trying to figure the cause.
P012B
P012C
P0EA7
P1DD2
U1424
Hoping someone has had a similar snag and found a solution.

can you post a tune and log?
that's pretty lean even for E85. I'd pull timing out of it if with 19 lbs.
Stock fuel system with a BAP?
Are you tuning it with ANN off?

Jay, stock fuel sys with BAP
Still running the NN.
The issue was the Max airflow table being to high. really that simple.
Car made great power 920whp-930wtq.
Some of those codes are permanent and cant be disabled but dont give a MIL. And they arent in the DTCs so I cant disable them.
Thanks for offering you input bud.
