Hello,

I have a wedge flash that Im trying to setup tonight and had some questions on the JB4 settings. My JB4 is the newest 28_3 firmware. The plan on running map 3 with NO meth. I know I need to do the following:

set FUE = 3 (meth disabled on all maps)
set FUB = 3 (Start at high boost target and disable all safety systems. Meth flow completely ignored)
Set menu 4 to 2 via steering wheel (always ignore DME boost target)
Set AFR and CPS values all to 0

What should the following setting be??

Meth Additive - this should be what my desired boost curve is so lets say 65?
Meth flowing scaling - no idea!
Start MEth Flow at - no idea!

Is there anything else I am missing? Thanks for any input!!

Your meth flow is disabled since you're using setting 3. For your additive, 65 is equivalent to map 7. 75 add is the most aggressive you can run. If you don't have 100+ oct then I wouldn't suggest anything over 55 add

You don't need to use setting 4/2, that's just an option for a more linear curve in power. Log 4/3 and 4/2 to see which setting is better for your car.

Thanks I understand the meth additive as the boost curve map shows the exact boost at RPM. I am running 93 with 40% ethanol and a flash made for this fuel.

My question had to do with the setting on the ethanol. IM basically looking for someone running the same flash to let me know what they sett he JB4 for when it comes to the other values. But thanks for replying!

Sorry for gravedigging

Anyone found the correct settings to use map 3 without meth?
