n54 jb4 2 step/NLS help

335boston · 02-25-2021, 07:53 PM

Hello all,

I got around to installing the NLS from bms, pretty simple install, set the boost redux to 0 and updated firmware after the install. I seem to be having some issues both with NLS and 2 step. For starters I have retuned the car so I know the tune is good to go with fuel ! But for some reason when I use NLS instead of smoothly going into the next gear and keeping a lot of boost the car bogs slightly and give me a huge jerk after the gear change is engaged? This happens I will say about 90% of the time. Over the passed weekend, I do not know why, I was able to get gears 2-3-4 to not only activate NLS correctly but also backfire into each of those gear changes along with the keeping of boost into those gears. Ever since this, I can no longer do it no matter what setting menu 8 is on nor how fast I shift. 2 step is also not working too well either, almost never dumps fuel for a backfire and will not stay on the rpm I set menu 8. If any one has any idea on how I could get NLS to work every time weather it be a mechanical issue or an issue on my shift any insight would be great ! Thanks so much!

Car is also FBO with e85 BEF running e30 at the moment due to the cold ! I have also purchased the BMS clutch delay valve thinking that it may be the cause of the NLS not being able to get into the next gear fast enough! LMK if anyone has ran into this!

After peeking at the logs I think the car isnt holding boost through the NLS

What setting do NLS users have set for menu 8? 4K? More or less?
