That makes sense to me. I did some tuning of the inj pw values based on eq error and with some minor adjustments I've been able to get it a lot closer.

Fuel system is otherwise stock. I don't think it's pressure loss. I'm not logging fuel pressure, but I do have a gauge and I've eyed it during WOT for that exact thought. Pressure stays solid.

So the ID provided data is pretty close for idle and part throttle. WOT is a different story. Car goes really lean and bogs. I must have something wrong with the injector data, but haven't been...
ID 1050x injectors installed. Startup and idle are fine. Time for some driving logs to see if that helps with PE.
In other news, I got my cold starts worked out nicely. ID 1050x injector set ordered today to solve the injector sizing.
So I got my inj dc logging fixed tonight. I'm barely running out of injector up top. Looks like it'll need larger injectors after all.
Here you go. This is the E85 version, not the one adjusted for 74%.
I don't see where that multiplier would apply other than the base fuel mass values, but perhaps.
I'm on pump E85. I have it measured at 74% ethanol according to the Innovate ethanol gauge. I can adjust my stoich for that. Still doesn't explain why the fuel mass multiplier works in the...
Update, first tests after switching over to E85 logged today. Fueling seems close, but in PE it's running tad bit lean. I left the Alcohol Fuel Mass Multiplier at 1. When I tested setting it at a...

Good to know on the startups and other tables. Definitely didn't plan on adding any timing until on the dyno, so we're good there. Appreciate the input!
I just want to sanity check my approach here if anyone is willing to lend some input.
I'm switching over to a straight E85 tune since this isn't a factory WB car like the Hellcats (so the flex...
