Just switched to E85 last night. (otherwise stock car)

Did my best to optimize the switch with given instructions:

* Went just over 20 miles past the low fuel light (just starting to move past the red line.
* Filled with E85 (Mininum E70 marked station).
* Only took about 2-3 miles and STFT & LTFT both shot up to 2x%
* Pulled over swapped to Stage2 EL E85 Map
* Drove 20 miles home being very easy and LTFT were 2-3% at part throttle cruise.

After a total of 30-40 miles of driving I took the following log:

LTFT still seems a bit high and just like on 93, still have a bit of random knock at 7k+
ADV still steady at 1, so not too worried.


Thinking I just need more miles, maybe with varied throttle input in different gears.

Thoughts?

looks same as most people. bit rich top end but may be due to leftover petrol in tank if its first tank of E85

The knock correction of -3.9 is a bit of a concern , could be due to low E%, but fuel trims look ok would have thought the fuel trims would have been more negative if E% was low. Something to keep an eye on.
