PE fail
Watch the video below and pay attention to my middle AFR gauge. Notice when I shift into third my AFR shifts back to stoich and stays there for the remainder of the pull. My tuner is trying to suggest I could have ran out of fuel pressure which doesn't make sense to me because of the point at which it went lean right when I let off shifting into third and the top of second didn't show any leaning out whatsoever. If it wasnt for meth injection I could have blown up on this pull. Definitely something I need to get fixed no matter what it is.

It is meaner on the engine. I did 3 pulls on the way to work today and they all went into PE like they should. I would think fueling issues would be consistent and repeatable. All the pulls were from a dig so trying to repeat the same conditions that caused it to run a stoich. Here is a video of my last pull.

Yeah still doing that. This was first pulls on straight pump gas tune BUT I just hooked up the water/methanol system to get an initial data log. First we add ignition timing to lean it out some and now we are modifying stoich to lean the rest of the way out to 12.5.
To add information about the issue I guess it was some DTC setting about the MAP reading too high (its a 1 bar MAP sensor) My tuner disabled it and it fixed the "not entering PE" problem.

No. All I have is a standalone IAT2 unit for post supercharger temps. I asked my tuner about setting it up to wire my IAT1 to read from a T-map and he said something about it wouldn't really do any good with my ECU. He's my only option for a tune so I don't try to challenge what he says much. I also can't run my knock sensor because it's way over sensitive and pulls all the power. Sucks but just the way it is. That is why I am really trying to figure out a standalone ECU because if it blows this time there is no way I am going back in with stock ECU. At that point though I might just throw my parts into a DF Goblin.
