Map 6 is currently not supported. PM me if you are interested in running it.

I do not have an aftermarket intake, nor have I dyno'd yet. Trying to find time, I guess.

The JB4 does not affect the exhaust burble, whatsoever. I run Map 0 occasionally just for kicks and there is no change. You can actually log in Map 0, which you could not do with the N54 JB4. It's useful to see what the stock tuning is doing and targeting.


2018 Audi RS3 | Stage 1 E85 and 91 Flashes | JB4 for Logging

SOLD: 2017 F36 440i Gran Coupe | PS2 | MPPSK | Track Handling Package | JB4

SOLD: 2007 E90 335i | PS2's | JB4 | FBO | 160k+ miles on the car, 120k+ miles on the JB4

Log, log, then log some more...
