    Check my Flex Fuel tables

    Hi,

    Wondering if you guys wouldn't mind looking at my tables for adding in Flex Fuel.

    Mods in sig and filename.

    For a go-by, I used the tables from the repository for a 2011 Holden Commodore which came Flex Fuel enabled from GM in AUS.

    Car seems to run great, just would like an expert set of eyes to check me.

    Many thanks in advance for assistance.

    I'm no expert
    Looks very close to mine. I believe mine came from a 2014 Caprice, I can't remember...

    Question for you
    How close does your sensor read to the actual Ethanol content? Mine was about 3-5% off When I was Ethanol free it still read 5%. With E10 it read about 13%. (I verified the content manually)
    I played with the Stoic table to compensate... So now when I'm at E0 it still reads 5% but my commanded AFR is 14.6 (or darn close)

    Hi thank you for the response. I never thought about the PPV, thats a great idea!

    On the FF sensor, I think mine is very close to dead on. When I originally installed my Banks iDash, I think I had a tank of 93 octane E10, and it read 9 or 10%e. I got a “BoostMonkey” test tube kit and pumped a quart of e85 into a small gas can before filling my tank, then tested the sample of the e85. Ultimately the tank mixture settled into the mid 70s with the e85 sample having shown 86% on the test tube….I ran the math to calculate, I think I had put the e85 on maybe 4 gals of e10…anyway it was dead on by the numbers. Haven’t checked it since, could be way off by now and I wouldn't know. U kinda worry me now!
