What fuel pressure do you have your e85 car ?
I have mine at 38 line off . As my car has 120 pounders. Per Eric chip instructions says to start there. My idle is at 14.5-15.0 on my wideband.
Thanks

Yes , line off . My car seems to start faster with higher base pressure and injector duty cycle is down 2-3% . I was looking to lower duty cycle as I was at low 80% , I'm now at 78-79 % .

2 of the stations near me are very consistant E85 ( tested ) and another one has " Flex fuel 55-85 % ethanol " listed on the pump . I tried it and it was E85 , probably the same supplier . The NYS Thruway has it at , at least one of the rest areas , right near Lancaster Speedway !! It tested E85 there also .

My base FP is 48 It needed it to keep up on the high end. Ideally you need to race it and see where your car needs it to be.
