Default JB4 various log runs for 2014 M5 - 07-14-2020, 10:57 PM

Attached are some logs from today. I installed the JB4 V2 recently. Running latest stable firmware and interface.

No mods, running E30 blend, which I think might be causing some fueling issues.

Map 0 , Fine obviousy.

Map 1 runs fine, maxes around 22 psi, AFR I feel like is all over the place, but runs fine, no hiccups.

Map 2 is where the issues are. I thought it was a spark plug issue since it was bucking pretty hard under load, so I bought some NGK 2 step colder plugs, gapped to .022 and installed those today. Went back out and did some logs and it feels fine in 2nd, then drops into map 4 safety mode. Not sure if its due to maxing out the fuel, or other. From what I understand, map 2 should max boost at 22, and in the logs, Im seeing 26-27 and even at one point 30 psi then goes to map 4.

No check engine codes btw.

Any advice would be much appreciated. Ill send some good ol KC BBQ your way if we get this sorted :D

Still needing help. Haven't tried running map 2. Map 1 pulls quite hard so have just left it with that. I assume the E85 is the issue, so trying to burn that out of the tank and can re-test, but if theres something else I need to be looking at, please feel free to point out anything you see.

Also, not sure if I would actually get any more benefit from map 2 compared to map 1 since 2 targets 22psi and Im already hitting that.
