I don't understand my IAM remains at 0.98 while my ethanol is around 80%. This is the first time that my IAM has fallen. It has always remained at 1 even with Ethanol at 65%.

Does anyone have an idea?

Here are two logs, one a wot and one normal.

Thanks.

remove some ignition timing from table Base timing B
under 2000rpm and over 7200rpm and sjould be good

tune looks good on your car i wouldn t touch anythjng else
anyway it s not a big deal 0.98 you still get basically full timing everywhere you could easily ignore specially if you are running e85 could not even be a real knock
