So if you built ztan original circuit and code for flex you may jave to modify the flex tune to work in opposite sense

Yeah I'm seeing a weird issue with his arduino code/circuit, it seems to be backwards from what you'd expect, presumably because of the tune if that's the case. I'm using wayno's latest flex tune. But with 93oct in the tank(so E10ish) it reads as E85 on OFT, but if I put some E70ish(haven't tested it, that's just the guaranteed minimum) into the sensor it reads around 30 to 40% ethanol.

You need to scale in reverse.

Regular:
Multiplier (Ethanol%/v) Offset (Ethanol%)
20.0 ... 0.0

Goofy:
Multiplier (Ethanol%/v) Offset (Ethanol%)
-20.0 ... 100.0

Well that's simple enough. Thanks for the help.

Bringing this thread back from the dead to ask a dumb question. I already went through all of the open flash website jargon in order to download the most recent OFS tunes. I clicked E85 but I never got the Flex Fuel tune. Where do I get an OFT OTS flex fuel tune so I can run the Delicious OFT Flex fuel kit?

you wont fing flex tunes or definitions on the oft site for download


they only supply the basic tunes for petrol or e85 for free


you have to pay for custom tunng to get flex tune


however i can also do opensource flex tunes if your interested message me
