Fiesta 1.0T not enriching at WOT
Hi,
I'm trying to tune up my otherwise stock (for now) 2015 Fiesta SFE. I've tuned my Miata with a Megasquirt, but this is otherwise new to me.
I started out with a combination of this guide https://forum.hptuners.com/showthrea...-Tuning-Guides
And the suggestions from Catnip's thread: https://forum.hptuners.com/showthrea...le-quot-thread
However both leave many holes.
I've increased injector max duty cycle to 1.05 (105%) and injection angle to 285 (up from 170).
I increased some boost limits and MAX TORQUE OP 1 which seems to be the only table in torque management that had reasonable values from the factory. That's obviously successful as I'm seeing more boost, which is good.
I've also changed the "Closed Loop Lambda at WOT" table to target 0.850 lambda where it was previously targeting 1.0:

I also changed "Fuel Enrichment Pedal vs RPM" which previously had "101" in the "2200" and "5500" settings.

I figured those 2 would get me enrichment at WOT before 5500, but I'm still not seeing it. I'm seeing "Fuel System #1 Status (SAE) = CL - Normal", the same as when I'm cruising, and the Equivalence Ration Commanded is still around 1 lambda.
I know I'm not a pro tuner but 14.7 AFR at 20PSI seems like a bad idea.

So, how do I get it to inject some fuel?
Thanks
