I recently upgraded from JB4 G4 to G5 ISO, so decided to log and try virtual dyno.

I did a 3rd gear pull from about 40-110 mph.
I'm completely new to logging, so help me out here.

Car: 2007 335i e92
Mods: Jb4 G5 ISO (30% e85) and Injen DCI

EDIT: I disconnected both long and short sliders in the ECU box to install my usb cable this morning, does that reset my map 5? This log is from my first WOT since the USB install.

Tried 40% e85 today and something doesn't seem right.

Was hitting 16-17psi with 30% e85, but barely hitting 15psi now.

Could you upload the CSV log files? Timing is a tad low but otherwise looks ok!

Here is the CSV file to the 40% e85 log.

Your timing numbers are low for 15 psi. At E30 ratio, I never drop below 10 deg at full throttle even below 4k rpm.

Will more e85 help?
Also, whats the dealio with my boost drop compared to 30%? Temperature?

Going by your 40% log, your IATs are pretty high. The avg ign also rose during the run @ 5200rpm, indicating that the DME detected knock and pulled timing. Remember Map 5 sets boost based on your avgign so the higher it is, the lower the boost target.

Thanks for the feedback!
Tried 50% e85 today, not fully adapted since I updated to ISO 20D this morning but things are looking better I think!

logs look good man, clean boost, timing, AFRs

Here is the csv

You look to be below target boost for a good while in that last log. If it continues to be a problem may need to check your solenoids. Otherwise looks good.

the E50 logs look great. A couple more runs will clean up the timing even more.

Also, on the E40 log, it looks like it needed more time to adapt.

Can anyone tell me how to do the logs and dyno on my jb4? Just got it
