So how do you enter?
You must have a garage set up showing you have an N54 based vehicle. Entries without a setup garage with picture will not be considered valid.
You enter by posting in this thread. You gain 1 entry for every rep point you earn after your post that enters you in this thread. You earn rep points by making posts and creating relevant threads.
For example, you post you wish to enter in this thread. You have 1 rep point at the time of posting. At the close of the contest, you have 11 rep points. That means you have 10 entries! The more rep points you earn, the more entries you get. Your own effort improves your chances of winning. Does not get any sweeter than that. For details on rep points and how to earn them, see this page: Reputation System
Note: Reputation for referrals is disabled during the time of the contest as people will no doubt abuse it having friends sign up or making dupe accounts themselves. Reputation will not be rounded up.
How long will the contest go for?
Until Christmas Day, Pacific Standard Time (may be extended until New Years Day depending on popularity).
What is the JB4?
The JB4 is an upgrade to the JB3 that replaces it's control box with a new much more technically capable box. 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. CAN specifically is the largest improvement allowing access to hundreds of new parameters, commands, and potential tuning features. 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. Additional features currently under development include autotuning to optimize power and safety on an ongoing basis, drag launch mode, adaptive PID to optimize boost targeting, progressive meth mapping, and many more to come.
