Jb4 boost limit @1st nd 2nd

eddi3B. · 04-18-2012, 12:16 AM

I was wondering if the jb4 has a boost limit in 1st nd 2nd gear. 3-6 feel like I'm getting more boost. Is that one of the options on the tune due to traction? And if so how can I disable this limiter.

There is boost reduction for 1st & 2nd but its not set by default so that is something you would have to have setup via laptop that is also how you turn it off connect laptop and set to 0 under user adjustments

Turn off DSC and try it

You need the USB cable and a laptop as its built into the software as a user adjustable option.

This is funny because I am trying to get launch control to work and it will not!

i have been trying to figure this out for a while.... it's a lot of adjustments on that user settings tab, but you don't really know which is optimal for your setup. I've asked Terry as well, and he refers to the default settings on n54tech... but, there has to be tweaks there and explanations per data field...
