* I also hope that we will share our experiences with the JB4 and our special tuning settings. Datalogging, reading & deleting codes as well as custom tuning concerns. In this thread we want to deal with the product features, installation and tuning related questions you may have. This thread MUST be about practical and usefull support for those using the tune or those that are interested to use it. We will try to alert you to those critical updates on this thread. To update your JB4 you will need a special USB cable. * The JB4 software is updated regularly and can be uploaded (for free). * Additional features have recently been added such as autotuning to optimize power and safety on an ongoing basis, drag launch mode, adaptive PID to optimize boost targeting, progressive meth mapping, progressive Nitrous mapping and many more to come. In place so far on the alpha are in dash gauges, shift light, built in code reading/deleting, steering wheel controls, on the fly map switching with confirmation, a completely new CAN based boost control system, cold oil protection, built in DPFIX, etc. CAN specifically is the largest improvement allowing access to hundreds of new parameters, commands, and potential tuning features. The new box features 5x the processing power, 2x the memory, better signal conditioning, a more robust power supply, integrated CAN communications, and additional inputs and outputs for future use. The JB4 is an upgrade to the JB3 that replaces it's control box with a new much more technically capable box. You can search the Net for answers or read the useful N54 Tune Comparison Chart (Pdf) attached at the bottom of this post. I also hope that this thread will be about the JB4 and not about the JB4 vs all the others. Yes, I have used and experimented with the Procede as well during its early development up untill 2010 interchangably with the JB 2 & 3 (at the time) when I decided to use only one tune and devoted my time to promote the JB4. Revo and I have a long relationship with the JB4 (Juicebox) from its inception and have experienced how the tuning company & its tune has grown, progressed and advance over the years.
#JB4 UPDATE FIRMWARE INSTALL#
There is a dedicated that deals with the JB4 only, but I still find people saying they dont understand all the technical jargon and seemingly complicated install and tuning processes. But I feel this support thread will assist (all of us) using this amazing tune. Most of the inquiries on the JB4 seems to be from registered members who are not active on the forum but is interested to try it out. Those of you that have made contact with me will know that I try my best to assist.
#JB4 UPDATE FIRMWARE HOW TO#
I receive many inquiries about the JB4 from how it works, how to install it and how to use all its myriad features.
