You sure it's got enough fuel in the MAF/VE?
You also didn't change the cylinder volume, so it still thinks it's a 4.8 engine size.
ohh yes thats true l need to make that change, ill make that change soon any other change i should make for the e85
seems to run but as soon as i let of throttle turns off.
Just like 5F said, adjust for the proper engine displacement, then you need to change the Stoich AFR to 9.8.Quote:

If it's a stock TB, you can open it up until your TPS is between 0.80- 0.82V. That'll be a great starting point.
I assumed he set the stoich to 10.50 because it's just pump E85 that is more like E70ish at a gas station.
yes e85 from gas station and throttle is an aftermarket ill look into the part#
thanks guys do need some help with this thing
throttle is a gplus cable driven not sure on the size, should be either 92mm or 102mm
In that case, I would adjust the throttle body minimum air screw until you get the IAC in the 40-60 range at warm idle.Quote:
