first HPFP log

Hi guys, im still fairly new on digesting all the information on the MHD logs for the B58.
Former n54/JB4 owner...
Just Installed the TU pump and updated MHD to the HPFP e40 map today, Xhp is installed too.

Wanted to share this and see what looks good and what indicators there are

I see some timing correction, not sure what it's telling me though. Or if it's an issue, timing advance looks like it's doing something.
I've installed new plugs already, maybe coil packs are getting old (2017 @ 59k)

I'm still a little green with mixing, using the ethanol calculator app and e85 test tube. Im pretty good with math (ENG) but could be doing the same mistakes we all once made. To date she's ran well on e30 with stock pump. Been watching Kern on YT to learn mixing. But definitely wanting to double check myself while looking for more power.

Thanks guys

Tried e45 per MHD, along with a few pointers to help get a cleaner log
My setup likes it

Finally an e50 log for comparison
https://datazap.me/u/dantesboyz/e50-...-40&zoom=9-108
MHD suggested I run e45 & e50 logs on the e40 hpfp map due to my barometric pressure (central Ohio).
I notice less timing correction on the e45 map and a hair more boost on the e50.
Note I did figure out I had to make some xHP adjustments in between the time these 2 logs were made. Didn't figure it out until testing 0-60 times against the dragy.
Launch control and torque limiters had some stuff going on, might explain the rpm step on the e45 log.

Looking for any feedback anyone has

Do you have torque limits set by gear with XHP? Torque seems low according to the "torque act. clutch nm" metric.

Your boost levels build slowly as you progress towards redline. My logs look much different than this when I compare. Is this by design?

I've noticed that value looks low, figured it was a factor type value.
I did have to go in xHP earlier this week and activate the torque limits and adjust first gear.
Didn't realize until finally trying some hard launching that I had surpassed thresholds, lost .9 on 0-60.
But now thinking about it again, in 4th gear I'm not sure it's a contributor
Does feel like my 0-60 is fixed now, haven't had dragy chance to verify.

Ok. I don't know how accurate or meaningful that torque metric is in the logs. But comparing to my logs when I was running stage 2+ 95 octane map I was seeing 640 to 650 newton meters.

The torque limits by gear in XHP is an awesome feature. I have adjusted down 1st thru 3rd gears in my car. Having some traction in lower gears is nice
