I didn't look at the log but I can guess whats going on.

Map 5 is an autotuning map that learns boost up or down based on a few factors.

Your map 5 learned while using e85 mix to increase boost targets. You then made a dramatic shift in fuel quality and floored it. Map 5 was expecting one fuel, but got another. Saftey map.

A few more runs and map 5 has learned down to accommodate the poor fuel quality.

Lesson is don't use a poor quality fuel above map 1 or becareful making octane changes, especially downward, when using map 5.

Even a few gallons of e85 makes a dramatic difference in octane.

The log posted is map 5.

Don't see much overboost there just really horrible timing. Definitely to much boost for your octane unless plugs and coils are old.

Post the map 1 log.

List your fuel, your mods, hiw many miles on vehicle, how many miles on plugs and coils, what spark plug gap 8s being used.

I don't see where you were kicked to map 4 in that log.

Why is your DWP set to 0?

Here's the link for the JB4 settings to go with.

When you exit map 5 and then go back in...it'll relearn.

Ok. Maybe it's an old code on the jb4?
I'm not familiar with timing just know I probably should be using 1 step colder plugs

Plugs are new . I wasn't told what the gap was but part number is zr5tpp33 coils not sure
Just got engine replaced with working used one and put upgraded rod bearings I posted more details a little while back I think you can find my other post it's a long story
Fuel is right now CA Chevron or shell 91oct
Miles about 92k
Mods
short throw clutch stop
golf tee mod
crowl delete
Metal charge pipe w/wmi bungs
BMS air intake
BMS JB4 Map 5 with MHD BEF
E85 about 35%
VRSF DP
Coated King connecting rod bearings

I'm not sure what happened to the logs for map 4 map it combines them? Or wont record cause I switched back 2 quickly.
I have it set to auto log with regards to pedal Input of 60% and 3 sec timeout. Should I change this?
Here is the log for mp 1
Thanks everyone for the great help

I'm not sure what happened to log for map 4 maybe it didn't record

I dont see the link
I'm not sure y my DWP is zero I'm must of been messing around to see if settings changed the sound and forgot to put it back
So just go to any other map for just a second then back to map 5 and done? If so then y did it throw me to map 4 more than once?

You need to put your DWP back to 60, save that, and then do a proper log and I'll take a look at it.

For proper review and the JB4 to adapt, please do logs in 3rd or 4th gear from 2K rpms to redline at wide open throttle.

Ok I reset my DWP To 60
As I don't feel comfortable to redline with my current issue due to my engine just being replaced I wanted to stay on the safe side so i filled up my tank with a E38ish at shell CA 91 OCT
Drove back to work from lunch about 3min then after work drove mostly home hit the gas a little on freeway got thrown from map 5 to 4 again then drove about 10 more min and did 3 logs like you asked 1 was 2k rpm 3rd gear WOT til redline then same in 4th 2 more times

Okay...initially you are correct, you overboosted but for you last log some adaptions appears to have taken place and the overboost is gone. I only see a few small timing corrections but trims are pretty good so you could add some more ethanol to clean those up.

Ok do you think I need to make some timing corrections. Or use colder plugs?

Do you recommend a certain e85 % mix?
Thank you for all of your help

I can't really say/deduce much based on that log...

Ok since last time I'll went through about 2 tanks of CA 91 then installed some 2 step colder ngk plugs from BMS and drove to work and back about 30 minutes each way and everything seems fine in map 5 didn't kick me to map 4. Did a log on the end of my run I did a pull with dct off 2nd gear WOT at about 2k rpm. I will do a few more pulls later this week when temps are cooler. Then I will try again with some E85 after that I will try to reset all adaptions to see if there are any improvements. Eventually I'll get my upgraded intercooler and maybe meth kit.

Also is it normal for my hijack temp gauge to show radical movements back and forth for over and under boost reading it seems to only do it with my foot off the pedal?

Here is an updated list of my current mods


short throw clutch stop
golf tee mod
crowl delete
BMS Crowl air filters
Metal charge pipe w/wmi bungs
BMS air intake
BMS JB4 Map 5 with MHD BEF
E85 about 35%
VRSF DP
Coated King connecting rod bearings
NGK SILZKBR8D8S (2 Step colder) Plugs
Gap .022

Not much in the way of timing and your avg ign is high. How does map 4 look? This is really strange, especially when running E35.
