doing a little more digging on this, the 2018 uses an "E80-A" ECM, where the 16 and 17 use an "E80" which is likely the difference. the flex has likely always worked once wired/enabled on the 18 models. GM did this same thing with the LHU ECU's a few years back. (and the chevy cruze....flex doesnt work on the 11, but does on 12+even though its the 'same')

we actually have an 18 ATS here which shares the same part number ECM as the 18 Camaro. im going to try to get that in tomorrow or friday to test the theory that its an 18+ or "e80-a" fix currently. if it is, ill look into swapping the 80-A core into our 17 (if its even feasible). and if that goes well, the 18 core may just be the fix for the 16-17 models!

thanks to the OP for trying this on an 18 model! if this is the fix, this will be HUGE for this community!

This means you guys need to get some HPFP's on the market as well as the high volume LPFP's. Throw in some higher flow inj's as well. hehe

Side effects may incluuuuudeeeee.

Seriously tho. The ability to run flex is going to push a LOT of people into more serious builds. Times will get faster. People will get more competitive within, and outside of this market. It will promote innovation and competition, which is ultimately awesome for everybody involved!

I'd love to see this come to fruition in any way. e85 is so scarce in my state that I would have no choice but to use a flexfuel option.

Coop, keep up the hard work dawg!

Just installed our flex kit on an '18, and it works perfectly.

we have had the kit installed the exact same way on a 16 and 17 since last year, and neither work. i took apart the 17 today to double check all of my wiring, and its all correct, it just flat out doesnt do what its told :(

i have not personally installed on a 'different car' but we have had a couple in here with brand 'R' kit on it (came in with it) same thing. i did fully remove, and re-install the kit on our 17 as a double check.

Dumb question but do you have to tune for all the different levels of ethanol or can you do a few different percentages and have the tuning software ramp it?

Fuel trims look good, HPFP good Question, why does advance say -3.5 in the table but +6 in the gauge screen?

Wait till you start putting timing into that e85 likes
