I really have no idea how either works. Just bought a used jb3 and waiting for it to arive. Looking for something i can install without having to mess with too much. To upgrade i just send in the jb3 and pay the upgrade fee?

What is the suggested value for FutureUseD at this point?
Any downsides to setting this to 2?

It took me like an hour but I was a wee bit drunk and also didn't have the right tools. Don't let the tiny nuts drop away when you're taking apart the plastic casing that plugs into the JB4 control box!

Some stuff that i cannot find what they stand for...
CAN?
PID?
TMAP?
CEL?

And is hijacking the term for switching settings and things on the JB4 or something else?

Thank you for the help

No need to really know any of those acronyms. They are just pseudo technical talk for those interested.

The JB4 is definitely worth the upgrade. If you bought from us and are considering upgrading definitely do it sooner than later. Once these first 1000 upgrade kits are done we'll probably remove the $85 option. This is just too much work for us to about break even.

I don't know why but this made me laugh. If you read Terry's instructions they are pretty clear on this.

There is no suggested value for future use D. There are three options:
1)leave it at 0 and nothing happens
2)set it to 1 and you disable the steering wheel functions
3)set it to 2 and you activate adaptive PID/Feedforward scaling

So it's up to you to decide whether adaptive PID/Feedforward scaling is a disadvantage. Most people feel autotuning is an advantage but if your not sure then I wouldn't mess with any values.

Oh and don't confuse my use of autotuning to mean that the JB4 has autotuning. The adaptive PID/Feedforward scaling is a type of autotuning not to be confused with full autotuning which Terry is working on and the JB4 will have.

CAN = controller area network
PID = pelvic inflammatory disease. Kidding. Some PID info here.
TMAP = temperature/manifold pressure sensor.
CEL = check engine light.

1)CAN is the short term for CAN-bus which stands for Controller area network
and basically is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer

2)PID stands for proportional integral derivative controller and is a generic control loop feedback mechanism (controller) widely used in industrial control systems

3)TMAP stands for Temperature Manifold Absolute Pressure and is a sensor. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's ECU

4)CEL stands for check engine light and hopefully is self explanatory

Anyone (especially Terry) correct me if I am wrong. Oh and Terry that type of PID is more my area of expertise but if you want we can always switch jobs for a day explaining what they mean.

It's an algorithm to adapt the boost control to your cars specific wastegate stiffness, mods, local conditions, etc. We'll be building upon it in future releases while we simultaneously add the other components needed.

As you do subsequent WOT pulls you'll see the FFMAX value under user settings adjust itself between 0-130. This represents how much of the duty cycle increase is fixed/hits instantly and how much is variable through the PID process. Ideally you want most of the increase to come through the fixed/feed forward as it will result in you hitting your target much faster than waiting for the PID to integrate to it. But if the value is overly aggressive you'll get overshoot and throttle closure. So the adaptive PID ranges FFMAX based on historic data collected during WOT runs. Right now its ranging one value which scales the entire 3D curve but the next step on adaptive PID will be to have it learn on a cel by cel basis (rpm, gear, target). This gets us 80% of where we'd like to be though with only 20% of the testing and work required.
Great explanation... I might not have looked hard enough but where is the FFMAX value in the user adjustment screen? Under information only? Would be interesting see the number change and share.

Hope i try it out tomrrow and get some logs in tmw or sunday before the game to compare with ma last set of JB4 logs.

You don't even need to do that. it comes preset to map 1. Just install, enjoy, and stop checking this thread.

Yes showing boost on the fuel gauge, shift light on the dash, that sort of stuff. Really cool especially with stealth mode on.

Can someone help me decode the datalogging variables (i.e. ecu psi vs pre-boost, misc, dmebt, ffpid, timer1, etc)?

ECU psi is what the DME observes boost as, DME BT is the DME's boost target, FFPID is the feed forward component of the pid control, and pre-boost is boost in front of the throttle body from the tmap sensor. Many are internal use and/or not relevant to customer use.
