Woops sorry
Map 5
ACN 91
DCT On (I forgot)

I will do some more pulls today, I think these might be because I was slow with the start/stop of the data logging

with DCT on is worthless logging. disable it completely and log. the map has to adapt so do first 3-4 full pulls 3-4 gears before logging.

Considering your fuel quality, it looks about as good as it can get.

Here is another log and CSV file (which i cant figure out how to add...). This time its with:
4gal E85, rest ACN 91
about 50F that night
JB4 Map 5, BMS DCI, DSC fully off
futureuseB set to 0
openloop at 90
boost limit 19

Timing looks a lot better with the E85 mix, and is running a hell of a lot stronger.

Any inputs? Or see anything thats wrong? Terry advised me that the timing drop around 4200 is normal when the VANOS changes over, which was news to me (couldnt find that in any of my searches).

Some other good information that would be good to note (that others including myself might not know), is that a timing drop (the red line) is "a 3 degree sharp drop at RPMs above 4500.

Thank you Terry!
