Yes, and E85 in the stock car is an eye-opener. Why would an AT be any different?

I was expecting to see values much higher than that. I was expecting to have to drive 20 - 30 miles before I saw the kind of numbers I did. Is this unusual? Has anyone else had the same experience or was your LTFT high for a while after flashing?

if you follow the proceedure i wrote then thats what should happen, i was just being cautious and getting people to check fuel trims before they went banzi, just in case all the petrol was not ot of the lines or they flashed wrong tune ect

Awesome. Thanks Steve. Following your process made the switch to E85 a cake walk.

just a disclaimer because I know the gearing is different but I have never been in an auto so I can't personally attest to the results.

I suspect the result of the OFT in a manual is much the same as in my AT, something along the lines of "holy shit!" The OFT tunes just seem to get better with each release.

Hi Open Flash Team,

there are my first 2 logs with the UEL header and Stg.2 93 flash.
Running on 98ron, outside temp was 1°C (34°F)

This one is right after the flash followed by 2-3 min. idle, and some 5km slow traffic driving.

The second one is after 25-30 km of mixed accel. and steady rev driving..

There is some weird throttle movement, dunno about ..was floored all the time.

Has anyone else not been able to log data? My save and record button are greyed out. The real time diagnostics run I just can't save anything. It worked for the first couple days.
