so that button on the box will be a 1/2 boost chart switcher?
Yeah, that's what I'm thinking now. Maybe 3 or 4 maps if we have the room... But, each map will also allow boost by gear and RPM, so they can get big...
I was serious... n2mb has only come out with great stuff that I've endorsed since the beginning.
you got a better shot of buying my dbb 50trim, than any blue box outta my car.
Thanks! Like the WOT Box, this product is going to mature over time. We'll just keep posting up the new software for it on our website for free as we get feedback and make improvements.
We don't have everything in the software that we want just yet, but we wanted to get it into your hands. It is already June and we wanted this early this season...
But, we also didn't want to rush it out too early. We are shipping with software release 1.21, which is the 21st release we have done. That's a lot of software and testing...
All the WOT Boxes (and Boost Boxes) are the same, so just follow the latest instructions from our website. Once you have it installed, load our latest software, also from our website and you'll be as good as brand new.
Sounds good. But as it stands now...the OG wiring set up will be ok with the WOT and the boost box installed together right?
We will post up a more detailed tuning guide later, but here is a rough overview of what is in the software now. We are hoping to simplify this in later versions of the software, so that the average user will have less things to configure, while still offering power users access to all the options.
Here is a quick rundown of the options currently in the software:
Boost Setpoints - Set your boost targets here for each gear. There are also more advanced options for boost by gear and RPM.
Overboost (PSI) - Set this to your maximum desired pressure. If the boost reaches this limit, it will be instantly shutdown, until you release the gas.
PID Limits (%) - This is the range over which you allow the feedback to adjust the output duty cycle. Larger values give the feedback more freedom to correct for boost falloff to redline or help with initial spool-up. Smaller values can help reduce overshoot.
Learning Range (PSI) - When the boost within this distance of the target pressure, the integral control and learning are enabled. A larger range allows the controller to adjust the calibration table for larger errors. A smaller range leads to greater stability.
Kp - Proportional gain. Higher values are higher gain, which offer faster response, but more overshoot and potential instability.
Ki - Integral gain. Lower values are higher gain. Lower values correct for errors in the boost quicker, but at the expense of stability.
The second screenshot shows the calibration table. This table will be adjusted as needed by the learning algorithm, so you may not need to ever look at this table or adjust it. If you do, it is there for you.

Should be fine. Which wiring do you have? The only thing I would recommend for the WOT Box is to swap the clutch switch input and add the crank position sensor input, if you are running the really old wiring. That way you can run the latest WOT Box software. The ignition coil wiring does not matter as much. Any of the options will work.
Can't u just hook up the external wg like a reg wga and just put the line on the bottom fitting like if your using a mbc and put the lower psi spring in the wg

It should work with the normal vacuum routing for the external wastegate setups. The only change I think we will recommend is swapping the normally closed and normally open solenoid ports. That way 0% duty cycle will equal minimum boost instead of 100% duty cycle. I think this a safer way to do it, since if something fails in the wiring, it is likely to fail open, rather than closed. Then, the failure mode will be minimum boost, rather than maximum boost.
stock map sensor wont be able to boost over 18psi correct?
That's correct. 19.2 psi. You'll need a MAP sensor with a larger range if you want to go higher. You can use the Mopar 3bar, AEM 3.5 or 5 bar or a generic GM 3bar.

then if i use the mopar i would need a diablosport to recalibrate the pcm or do they work with stock pcm just by hooking it up?

You will need to recalibrate the PCM if you swap MAP sensors. You could use an external map sensor, like the GM 3bar, but you will need a tuning solution / map clamp to get the fuel tune right once you exceed the limits of the PCM MAP sensor.
Could you explain this a little more? Is this geared for a stock turbo type setup?
Thanks
Sure. Right now it is setup to only control boost at WOT. When you are at anything less than WOT, the boost target it set to 0, so you make only the wastegate pressure. Without this, some smaller turbos would make too much boost while in closed loop at part throttle and the engine would go lean. With this simple control, the boost won't exceed your waste gate spring pressure (minimum pressure) until you floor it.
In future releases we are going to expand on this and make a full compensation table that allows you to smoothly tailor the amount of boost you get for the throttle position. For now, it works pretty well at being driveable and still perform.
