AFR targets at loads higher than 2.50 ATR/ATP fix

[chaser27]

Now I just need to get fast enough to hit 2.5+ loads.

So apparently, this became relevant to me quicker than I had expected. I've been playing with my tune, it was cold this morning and bumped a 2.52 Calc Load today. Just like @superskaterxes; was seeing, my AFR goes rich as hell on a Gen 2 and stays there until it corrects itself. I'm attaching my log for anyone that wants to take a look-see and a graph that shows the ECU going WTF and fixing itself.

That looks more like the WOT trims running out of room, then suddenly kicking off (or on, not sure what the target vs actual is. Your axis scaling sucks ).

I'm targeting 11.4 for now while I figure out how things play with each other. And they have been hitting almost dead on until the 2.52 today

Did you verify that this is not the case when loads are below 2.50 with an A-B-A test? Almost looks like SWAS was involved there.

Yes, I was actually just looking at it. Temp rose almost 20 degrees between logs and I only hit like 2.4 or so. AFR's are rock steady.

I can't wrap my head around it... maybe the phantom OL fuel trims @atvfreek; (I think it was) was talking about?
I don't want to do a MAF adjustment like @ms6mil; is doing, because I don't really hit 2.5 ever

Concerning SWAS, only if my sensor is acting up, dead straight road and slight uphill. Not really getting torque steer

Attaching log.
