***It works***

I filled up at a United station close next to work yesterday and they now have E85 supply there which they didn't have 6 months ago, and do not advertise it on their website.

Having implemented Hybrid Speed Density and Boost Limit Fuel Cut for my car, this is a logical next project which I'll develop openly and collaboratively until we have a solution or I lose interest or my car.

I do this for a hobby, so it need not be said, but ***TRY EVERYTHING AT YOUR OWN RISK*** My time is my own to waste on this project and I do not earn money as a tuner - having said this, I'm happy to take donations via PayPal at esltan@yahoo.com if you find any of the info that I've posted useful.

To do:
Source Hardware: tips at http://www.ecmtuning.com/wiki/ethanolsensorparts
Define Flex Fuel Sensor input method - Posts #3, #5, #11

Develop code to:
Hook the sensor routine - Post #14
Read and scale input to E% - Post #15
Scale PI and GDI separately or together based on E% - Post #31
Scale cranking PW based on E% - Post #32 (v.1), #46 (v.2), #49 (v.3)
Interpolate fuel and timing based on E% - Post #36 (fuel), Post #42(timing)
Apply scaling to display multiplier - Post #50

Extras:
Send E% data to PLX gauge - Post #11, #48
TRAC switch double click to turn off traction control or default to TRAC off - Post #30

email me if you want a copy of any of my files along the way.
