E85 PE question

[wtf777]

It's the alcohol multiplier table. That's what multiplies against the density. Quick and easy thing to do is to put the same one in that the SD side uses. Won't be right but its a heck of a lot better than the stock one. Right now you're over 30 % lean at times running the stock table.

thank you after reading few times i am starting to understand, again my English not the greatest. hopefully tommorow i get a chance to work on the vette.

The stock flow rate mult factors in the actual fucking density of the fuel. Go look up the density of ethanol, then the rough density of gasoline, and divide the two. Compare to that table. What does that tell you? Follow the bread crumbs, jesus. If you're going to just hack shit up, you might as well rape the PE table like its 2005.

if i knew what the fuck you talking about i wouldnt be asking questions would I? thanks for input "advance tuner"

Do you have a wideband in the car? If not, then you're flying blind. The mods you're tuning for are pretty simple, you might want to consider hiring a remote tuner to get it fixed up for you and then you can have a safe starting point to toy with the tune. For you mods you don't need to set the Alcohol PE any different than the Gasoline PE. You don't need to touch any density multipliers. But you do need to use the correct stoich values, populate the Ethanol Spark stuff, enable the Flex Diag and sensor stuff, and address the Torque Model for Ethanol. Early Gen V ECU's used different Torque Models for E. I'd rather have the car behave the same on 93 pump and on E.

ok that makes sense. my starting point was last tuners file that did original 93 tune it seems he changed alot. thanks
