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: http://datazap.me/u/joneze93tsi/2014...&data=1-6-9-12 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? |

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. |
