NA E85 Tune, looking for some input
They are not Ford 30's, they are a Saab only use but they do look the same just a different part number. See the picture I posted?
I am not sure what you mean by what did I use? in 99 or 00 the Vette fuel system changed and this was the new rate due to the removal of the FPR on the rail and its vacuum adjust to putting it in the fuel filter and keeping it at 58psi always.

Your tune in very close:
38.69 38.88 39.06 39.25 39.44 39.56 39.75 39.93 40.12 40.24 40.43 40.61 40.80 40.92 41.11 41.30 41.42
BUT in the end it doesn't matter.
Those injectors absolutely CANNOT keep up with E85 needs for that motor.
STOP!

I agree thats why I had larger injectors next on my list, thank you for the math I am concerned now because honestly it does not say how to tell the difference on these injectors... what fun.
I will go check what you have there vs mine and make changes thank you for the information. That means 42's should be around 47-48. Finding something bigger is going to be even more fun. I am running way to rich though on the old tune they did not go this high I think I have a data log from then let me check.
