Starting to build a max effort tune for my 06, but I am running into a air limit issues that is causing The truck to defuel and have delayed shifts.. I have been looking on the forum and havent found anything on air limit fuel correction.. Looking back over the tune I Cant find anything that jumps out to me.. hoping someone can point me in the direction to fix this! Thank you! && Happy New Year!!

Haven?t taken a full look at it yet but one issue I see is in the upper rpm, you yank fuel 3220rpms and that?s where you are running into the air limit as well in those upper rpms.
Possibility you are bouncing off the ?Max Airflow? limit table.
Ok thank you, I have my pedal map set to 0 at 3600rpm. and 4000rpm maybe I should raise those? and my max airflow table is maxed outQuote:

In the tune you emailed me, if it?s the same as what you posted in this thread, isn?t maxed out.
Yes I see that.. I thought I did.. fixed now! Going to test drive it and see how it does!
Issue is still there with airflow maxed out, rpm raised, and pedal map raised

with your full throttle fueling Transient, it only fuels to 3220 RPM where it cuts out again. I still don't know if the proportional, Integral and Derivative positive limiters will actually limit your fueling. I'm not a dodge guy :shrug:
Ok I?ll take a look at that later today!Quote:
