New Product Announcement - The Boost Box! Boost by gear for the SRT4! - SRT Forums

phrozen · 05-31-2009, 11:23 PM

N2MB Racing proudly announces our newest product, the Boost Box!

The Boost Box is a new electronic boost controller for the 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.

Adaptive Tuning

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.

Overboost Protection

Programmable overboost protection shuts down your boost instantly if you exceed the threshold.

Easy Installation

The Boost Box installation simple. It only requires splicing 6 wires! It can work with your existing solenoid and map sensor. The connections are:

* Power
* Ground
* Solenoid Output
* MAP Sensor
* Throttle Position Sensor
* OBD Bus

Windows Software

Our Windows software makes setting up the Boost Box easy. You can download the software here. Take a look at these screen shots for more details:

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, our Boost Box software upgrades are 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. If you want both options, order our WOT Box / Boost Box combo and we'll send you two boxes at a discount!

Included in the kit

* Boost Box
* USB to Serial adapter
* Universal wiring harness
* Heat-shrink tubing
* Ground lug
* Zip Ties
* Installation Instructions

Videos!
Updated videos coming soon, but here is an older video as a teaser!

Ordering!

As an introductory special, we are offering the Boost Box for only $169 + shipping! Plus, if you buy the WOT Box and Boost Box at the same, we will drop the price to $330 + shipping!

awesome! how well does this work with an external gate?

phrozen · 05-31-2009, 11:28 PM

We should know soon. Jay was testing that this weekend. It should work the same, but we just wanted to make sure.

rico's-srt · 05-31-2009, 11:36 PM

will be placing order soon

amdguy · 05-31-2009, 11:59 PM

do you have a chart of rpm vs speed? been looking for one and cant find it (for 1st though 5th)

Roc IT Man · 06-01-2009, 12:36 AM

awasome i need one for ext wg let me know asap

dsmlights@rage-tek · 06-01-2009, 12:50 AM

nice product guys, soon you will have a complete standalone built for an SRT

sideshosk8 · 06-01-2009, 01:02 AM

man, I was about to jump all over this! I gotta wait til the external gate testing is done.

boogaloo shrimp · 06-01-2009, 01:17 AM

bout time woooootoototootttt!!!

questions:
1. is there a simple push button high/low boost setting?
2. can boost be set to stay at a certain psi, can i set the box to spike/hold and drop? also can i set it to hold a desired psi until redline? thanx cant wait to get some spare coin

marakka · 06-01-2009, 01:28 AM

Simply wow. Great work guys.

Now I gotta find $330.

rolla4now · 06-01-2009, 01:34 AM

can the wot box/2step combo be used with this...?
if so, how would the wiring differ?

xXSilentScreamXx · 06-01-2009, 02:16 AM

will this replace my greddy profec and do i just type in how much psi i want to run and do i have to have pcm controlled boost?

answered above

appparently they wire the same and the boxes can convert from boost to wot.............

thats how i took it

Do you mean just the numbers? Or are you asking if the RPM vs speed computation for gear is adjustable? It should not need to be adjusted unless you have changed your transmission gear ratios or maybe if you have changed your tire size in the PCM. I will make those numbers adjustable in the software just in case someone needs to change them.

If you are looking for the numbers, I don't really have them handy right now. I have them in some crazy format. It is in KPH vs revolutions per fortnight or something ridiculous to match the PCM data.

The second boost map for switching with the button is not in there yet, but I should be able to put that one in the software this week. That feature is pretty easy to put in the code.

The boost targets are programmable for each gear. Once set, the boost controller will try to maintain that boost setting for each gear across all RPM, including up to redline. It is now holding boost to redline better than it shows in the video. We will post up a new video soon.

The amount of boost spike will be determined by how high you have the proportional gain set. If the gain is higher, you will get more boost spike and slightly faster response. If you drop it lower, you will have less boost spike and a slightly slower response.
