Did you ever plug the USB side to a computer to adjust the box's settings?
Was software for it included?
No CEL with the downpipe, in case there's one for the NX made in the future?

Thanks in advance!

 

Yes i have. You just need to buy the BMS data cable and you can download the JB4 application for free online which allows you to increase the boost settings. The box is already set at +4PSI (default) which is safe for a stock engine setup. If you were to get an aftermarket down-pipe then you can increase the boost settings to 5 or 6psi, but we found that 5psi was the best setting for this size turbo. You will also need an O2 sensor spacer to avoid the CEL on an aftermarket down-pipe.

 

Has anyone try the BMS Stage1 on an NX 300?

 

I sold a BMS to a NX owner and it works just fine.

 

Did anyone who has a box measured the time of acceleration before and after with any kind of device? Racelogic? An application reading from OBD? Stopwatch at higher speeds?

I look for the information as I had Racechip GTS in my IS an the time from 60-120 was 3 secs worse after the box. The dyno says the torque is increased, but it looks that there is something else which is not cooperating after the box.
