Weird timing delema +4 knock

[WildHorse]

2017 Mustang GT. Pump 94 octane. Just tune / CAI / off road catback. WOT hit in 3rd. 3000 rpm - 4100 rpm added 3 degrees added. 4200 - 7300 took away 3.5-4 degrees. Added 1/2 degree at 6000 another 1/2 degree at 6700 all the way to 7300 for a 21.5 - 22 degree total timing. Normal should be 26-27 degrees I think ? Could it be bad gas ? False knock ? Fuel trims are bang on with the PMAS. I figured with bad gas it'll remove timing from everywhere ? Otherwise it pulls like a freight train. Thanks for any input.

Edit: Upon further review, I think I seen what's going on. Seem on the 'hit' it went +3 and timing dropped to 21.5 Tried to add -3 for a few hundred RPM, then went back +4 above 5000. So that means bad gas if I'm reading it right ?

Seems pretty low for N/A. I got around 27 degrees pretty easily with 93 octane on a stock Gen1 in 3rd @ WOT.

Run that gas out and try a different station. If it still does it you may have false knock or some other issue going on.

That was the problem. It was tryna maintain a 14.6 stoich at WOT. Thanks for the hint.

Any reason for it not going into power enrichment @ WOT ? Thanks.

I don't understand, Ford uses lambda, stoich = 1

So are you commanding WOT 1?

It should be something like .83

What made you adjust the power enrichment/wot fuelling parameters? I use 0.85 for wot. Stock settings start at 0.85 and richen to 0.825 or something like that as the rpms climb.

I didn't adjust anything. Just trying to figure out where my tuner 'messed up'. Anybody have the stock fueling tables ? Thanks.

You should be able to find one in the tune repository
