This is my first attempt at a log with Map1 with my new JB4. Any feedback would be great ly appreciated!

[AWDGT2]

Log looks good. The only weird thing I see is that the JB didn't kick in until 63 mph. That's where ECU psi and boost started to separate. Never seen that before.

[Jluppens]

Interesting. Any theory on why it took the JB4 so long to kick in?

[AWDGT2]

Not really except that it's a new install and it might have taken it a second or two to start intercepting the signal and get them to the ECU. Most certainly isolated and I bet it could never be replicated.

Looks like its due to warmup protection.

[Jluppens]

Very possible, car was not warmed up quite as much as it probably should have. I ran another log in similar conditions today.

[AWDGT2]

Log looks perfectly normal.
You can go Map 2 if you want.

Here are a couple of Map 2 logs from today.

The look normal.

[Steve @ BMS/Fuel-It!]

Agreed but try to stay WOT when logging.

[Jluppens]

Just added 5 gallons of E-85 and the rest with 91 octane. I ran another log using Map 3. Wondering how it looks. Thanks!

Not bad, but not great. Your loosing a lot of boost shifting at redline. Shift manually at 5600, bit less in 1st and 2nd. Have you reset your learned timing corrections? Negative off for 10 min, reconnect, don’t log until .8 disappears in ign 2-6. Takes about 15 min of driving around. Put it on your phone app to view live. If you don’t see .8 across 2-6 it did not work correctly.

I pulled the negative for 10 minutes. Now I get 0.8 across ign 2-6 when giving it gas and drops back to zeros on coasting. Shortly thereafter I saw a bunch of 5.3 show up across ign 2-6 and I check the codes shortly thereafter. Got a laundry list of codes but I could not find a single one in any code lookup. Looked like a bunch of jibberish. When I got home, I rescanned the codes and did not give any codes. Not sure what that was about.

That’s normal on the .8 and when driving to see it spike a little with what I call higher torque low rpm is normal. If it’s happening all the time it’s it’s basically saying your fuel is bad. Why you got a bunch of codes is weird. I keep 2 cylinders, one on each side all the time.
