2018 Mustang FF ethanol% vs AFR

[Rabbitt]

I just want to make sure I didn?t set the Flex Fuel Ethanol % vs AFR table up incorrectly. Thank you in advance.

14.6 10%
13.9 17%
13.3 25%
12.6 33%
11.9 41%
11.2 49%
10.5. 57%
9.8 65%

It's wrong,

9.76 = 85%
14.08 = 10%

I found this spread sheet a while ago. Thought it had good details.

Just reference a 2018 F150 calibration..

Believe it or not, when you try to command the individual percentages like that, it doesn't read accurately. Just follow an f150 calibration and it works.
