What is the WOT Box?
The WOT Box is an electronic device that makes WOT shifting easy by reducing your engine’s power for a very short timed period while you shift. It allows the synchros in your transmission to mesh easily, reducing the chance of missing a gear and damaging your transmission. If the input shaft on a manual transmission is not allowed to slow down enough it will lock you out of gear time after time. We have developed a solution to the problem by controlling the ignition at the shift point to ease the transition from one gear to another.
What is WOT Shifting?
WOT shifting is a common practice used by drag racers regardless of if they are running turbo, supercharger or naturally aspirated. WOT shifting is accomplished by holding the gas pedal to the floor and never “lifting” off the gas during the shift. The problem with doing so is when you depress the clutch engine RPMs flare up and a brief amount of time is required for the transmission input shaft to slow down. Even the most successful drivers have been known to miss a gear occasionally. It requires complete concentration and lightning quick reactions in order to pull it off.
“Keep the pedal to the metal, blip the clutch, and grab the next gear. Do it fast enough before the redline, and your reward will be a zero lag, constant boost shift.”
When you WOT shift, your engine is still producing peak power through the shift. With the clutch released, the engine revs up. This increase in RPMs and the full output power of the engine makes it very difficult for the synchros in your transmission to engage. The result means that WOT shifting can be very difficult and potentially damaging to your transmission.
How does the WOT Box make WOT Shifting easy?
The WOT Box momentarily disrupts the engine power long enough for you to make an effortless, fast WOT shift. The result?* Lower ETs – One of our big turbo customer cars dropped their E.T. in the quarter mile from 12.0 to 11.3 seconds just by adding the WOT Box!* Reduced chance of missing a gear* More consistent, effortless shifts* Reduced wear on the transmission* Reduced chance of major transmission damage
How does the WOT Box work?
The split second that you place your foot on the clutch pedal with the throttle all the way down, a signal is sent to the WOT Box that a shift has been initiated. When the module sees the signal from the clutch switch it will reduce engine power by cutting the ignition. The ignition control is a precise timed event that the user has complete control of. The box is capable of controlling ignition from 25 milliseconds to 700 milliseconds in 25 millisecond increments. With a range like that the wot box can even make Mr. Magoo look like a seasoned pro!
The drivers in our test cars describe using the WOT BOX as sitting in the car and going through the gearbox with the engine off!! All the drivers were amazed at how smooth the gearbox was. The transition from gear to gear is effortless and the boost gauge would barely show a blip between the shifts. We were able to test on an Evo8 with a laggy 60-1 turbo and managed to hold 30+ psi through every gear! Even on a stock turbo equipped Dodge SRT-4 we were able to knock 3 tenths off e.t. by simply hooking the box up. Our big turbo SRT-4 cars were able to drop up to 7 tenths off their E.T. with the WOT Box alone!
The No-Lift Shift feature makes no-lift shifting easy by cutting your engine’s ignition for a very short period while you no-lift shift. No-lift shifting is keeping the gas down through the shift. The ignition cut allows the synchros in your transmission to mesh easily, reducing the chance of missing a gear and damaging your transmission. Keeping your foot down through the shift also allows you to hold boost through the shift, thereby significantly improving your E.T.
2-Step Launch Control
modulates the ignition by cutting power to individual ignition coils to hold the RPM you want to launch at. The turbo will spool up while you do this. You can use this feature for a more consistent and more powerful launch in boost!
Will the WOT Box affect normal driving?
No. The WOT Box will only activate when you are WOT Shifting. Normal shifts will be ignored and continue to work just as you expect. You won’t even know its there, until you make a WOT Shift!
Will I be able to program it or do I need an engineering degree?
Many after-market electronics are bulky and full of dip switches, buttons and dials that are enough to make the average DIY’er bang their head on the wall in frustration! The WOT Box is simple to program with only one button and one LED.
What is involved in hooking it up?
No new hardware is needed. The installation will only involve hooking up a few wires. Full instructions are available on the N2MB website.
Do I need a clutch switch?
No, you don’t! Most recent cars have the clutch up switch already built in. If you have cruise control, you likely already have the switch you need.
How big is it?
It’s small enough that you will be able to hide it up in your dash. The exterior dimensions are 3.8″ x 1.6″ x 0.8″

If your WOT Box still doesn’t respond and isn’t fixed by powering it off and then on, then you may have
lost your settings and must perform the Recovery Procedure.
1. Connect the WOT Box to the computer with the serial cable and make sure that the WOT Box DOES
NOT have power.
2. Open the User Interface, select your COM Port, click either the single or dual feature box
(depending on your WOT Box), and click LOAD FIRMWARE.
3. When you see the prompt, power on the WOT Box by turning your key to the “on” position.
4. Note: If your vehicle does not provide power to the WOT Box with the key in the “on” position
without the engine running, you will need start your car in this step. Start from the “off” position
and smoothly but quickly go to the “start” and then “on” position after the engine has started. This
will allow continuous power to be provided to the WOT Box to allow the firmware upgrade to
complete. Known cars that require this are the Dodge Neon SRT-4 and the Audi A4.
If you’ve performed the procedure correctly, the WOT Box will be programmed and the interface will
display the stock settings. Once you see this, the recovery procedure is complete, and you can change
settings again.
