Is this in the low RPMs like less than 2500?
Attachment 71257Attachment 71257Looks like it takes some effort
No this is the entire rpm range.
Rescaled throttle % threshold and set anywhere from 40-75% and continued to do the same. No pe delay nothing I can see immediately causing it. I have only seen it on 1-2 cars now out of about 15 or so I have done. Just wanted to see if anyone had come across the same thing
I will investigate.

Same thing happening to me now on a boosted Coyote S550. It happened before on a 2015 GT. I've been making it a habit to set fueling to richest desired on the last row of the cold enrich table on them now. The one I am tuning now goes between cold and regular.
For NA i set the pedal position to 65% and top 2 rows of closed loop lambda to .820
Do you have a datalog? I have seen this on s550's, normally the Fuel Source shows "EGO Monitor test", when this is shown it does not seem to matter if you go WOT, the car will not allow PE to activates regardless or TPS or load, as seen in my screenshot below.

Any update?
What modifications have been done to the car, is it OEM?

Has anyone figured this out? I have a GT350 here now with a Procharger that does the same thing...stays in OL cold Enrich at wot. Luckily I also match the top row of the cold fuel tables to my commanded WOT.
