Did some data logging after installing fuel wires. Afr seem a bit low for having fuel wires just wanted to make sure everything looked good in these maps. Will be running map 2 and 6 most of the time. Let me know if anything stands out and also if I should adjust my map 6 boost ramp. Also this is for a stock q50 3.0t premium. Thanks! It's goes map 6,6,5,2. I also added my map 6 log with WOT only.

@Boxy or @Ddnspider may be able to help you out with your particular request, if you can dump the log files into a .CSV format
it certainly would make things a bit easier to review however.

Also love that profile picture. Hah

I prefer graphical displays of the data logs vs. spreadsheets also. It's easier to evaluate what's going on.

Fr the app you should be able to select the parameters you want graphed. You want both boost banks, both afr banks, ign1, trims, rpm as a minimum.

I'm not 100% good at reading JB4 logs but it seems like your AFR is at good place during WOT.

Are you using 91 or 93 Oct gas?

Ignore timing drops right at the shift. Otherwise shoot to keep it at 5 degrees or above, but look for timing to ramp up with rpm.
