On 2015 Mustang what tables update fuel at WOT

[Kcc0521]

I am trying to diagnose a rich condition on my car and I am curious what parameters update Lambda at WOT and how does the computer update it based on learned data from LTFTs?

Short term only at WOT not long term. Mostly just going to have O2 sensor feedback being used unless you hit cat over temp protection making it command rich.

What about the KAM table? Is there any reason for WOT fuel to change if you flashed a new tune that only changed Transmission data but reset all fuel trims?

No. After 0.85 or something like that load it doesn't use LTFT on stock tune. Don't think you can even raise it to over 0.95 but can't remember for sure off the top of my head. I know boosted has no LTFT at WOT

Nice. Thanks for sharing that link. I am tuning a Roush S550 tomorrow and will experiment with that some.
