I see this all the time with 04+ on hpt, you have like 12 adjustments and they don't ever seem to offer everything yas need

look for other hpt supported OSID files for yer car...one of them may be better mapped

in the case of my compG, hpt is mapped out well on the "OLD" OSID from the cars release, but the newer updated OSID that the dealers flash em with is barely mapped.

most mild builds don't really need access to everything, id doubt youd need to skew injectors

So what would suggest I do to try to tune for E85? Is there another way to tune for the larger injectors and add more fuel. Again, sorry for my newbie questions.

I'm not using HPT, but when I tried the injector Skew in DHP for my 05' it didn't do anything at all. I got the same lean code and I ended up changing the injector flow rate by 34% and now I don't have a lean code anymore and my trims are pretty close to 0. I did get a P0420 but it went away.

You need flow rate vs kpa....

but all this is going to be pointless if youre trying to run this with stock injectors...

If I were you, Id forget e85 til you get the tuner figured out and car dialed in.

Then... put your bigger injectors in, scale the rate vs kpa to fit your injectors accordingly, change your fuel filter 1,000 times, and do a couple more scans and adjustments once your on 100% e85.

Done

He's got 50# injectors is what he said. I'm running stock injectors and my car is doing fine. I don't know why people keep saying you can't run stock injectors on E85. As long as you don't exceed their flow rate they will work just fine.

You can also run a 2.8 with no mods... doesnt make it a good idea....
