    LT1 bin file for E85 fuel.

    Dear forum members, Im a new member here but have been reading here a lot, thanks for all useful info.
    I have put a camaro 1994 LT1 350 V8 controlled by a pontiac PCM and a Buick roadmaster 4L60e tranny into my old 1984 gen 3 camaro, everything fits fine just bolts on without problems and works nice, here in sweden a 1984 camaro is seen as old red neck ferrari and does not draw same attention from authorities as a shiny sports car. As Im also building a house and had a second child late december my late evenings in the garage is now easily counted so I now kindly ask if someone has a bin file to the LT1 for ethanol e85 that could be sent or posted here ? Im hoping to save time by modifying something allready working. My long term goal is to have the lt1 supercharged but I have to take small steps as my time is divided to a 1956 fairlane with a -89 302 efi and a suzuki tl 1000 V-twin, also EFI =0).

    By the way, the caddy vp4 bin file with towing option posted here seems to be slow in lock up ? I was thinking with towing option the lock up would be activated right after gear shift ?....or maybe its time looking for another tranny...again.

    Kindly Peter.

    since the stoich constant hasnt been confirmed in $EE... you can just bork your injector constant.

    since e85 is 9.765:1 vs stock stoich 14.7:1, you can just take your stock injector constant and multiply it by 0.664.

    that should put you in the right ballpark.
