The Boost Box is a new electronic boost controller for the Dodge Neon SRT-4. The Boost Box is remarkable in its simplicity and power. Here are the major features:
Boost by Gear
The Boost Box automatically determines which gear you are in and adjusts your boost level to your desired setting. This is crucial for maximizing the performance of high horsepower street driven cars! You can easily limit power in lower gears and still have full boost in higher gears.
The Boost Box can automatically learn its calibration tables as needed to make the amount of boost you program. This helps simplify the tuning process. Or if you prefer, you can take over full control using our Windows software.
Throttle Position Sensor Input
The Boost Box monitors your throttle position to adjust boost as needed, eliminating part-throttle overboost.
The Boost Box installation simple. It only requires splicing 6 wires! It can work with your existing solenoid and map sensor. The connections are:
- Solenoid Output
- MAP Sensor
- Throttle Position Sensor
- OBD Bus
- Windows Software
Here is a quick rundown of the options 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.
Free Software Upgrades
Just like the WOT Box, N2MB provides Boost Box software upgrades for free and available on the Boost Box Software page.
Compatibility with the WOT Box
Not only is the Boost Box compatible with the WOT Box, it can be turned into one. Just load our WOT Box software onto your Boost Box and it can become a WOT Box. Similarly, a Dual Feature WOT Box can be converted into a Boost Box by loading the Boost Box software. However, the two features cannot be used at the same since the wiring is different for the two functions.
