I was thinking the same thing. ???

Is your boost also tapering off at high rpm? Mine is around 19 - 20psi up to 5500rpm and the tapers of to about 17psi at 7000rpm on Stage 2, 91 octane BM3 map. Thought that the BCM can help here to keep the boost at a higher level at high rpms ... hence the idea of JB4 + BCM on map2.

Not sure if my boost is dropping, just planned running the JB4 also since I was running that before flashing with BM3. Figured that the JB4 would always make my car hit numbers.
Did you upgrade your spark plugs yet?

Yes, have changed to two step colder NGK plugs and gapped them correctly. I am at 5000ft altitude so turbos have to work harder.

Today I pushed a bit the car at 240km/h, and I got cylinder misfire.
JB4 with water meth running maximum 22PSI.
Is this normal ?

Hello,

How can I find what is causing the misfire when I am WOT with the methanol enabled ?
I do not get this with map 1 for example.

thanks

Could be a variety of things ranging from a defective nozzle to some physical issue with the car like a plug, coil, or injector.

JB4 log of issue would be a good start though.

It's not much of a difference, same mapping guide is used for CP vehicles.

Had both our 2015 F10 M5 and 2018 F90 M5 out at NFZ this weekend for some half mile action. Managed to get a couple side by side races in the video below! Best trap of the day for the F10 M5 was 167mph @ 27psi (map8), and for the F90 166mph @ 25psi (map3).

V2_2_3:

1) Logical change to allow boost to target below the factory boost levels, especially useful for those using flash maps in conjunction with the JB4.
2) Adjustment to code read functions, may need updated interface to properly read codes from both ECUs.
