N2MB WOT Box Installation Instructions
NOTE: If you have a CDI (capacitive discharge ignition system) please contact us at
support@n2mb.com for additional instructions. Damage to your WOT Box can occur if the
installation is not completed correctly!
WARNING: Spark‐based rev‐limiters can damage catalytic converters. If you have catalytic
converters on your car, N2MB accepts no responsibility for damage caused by the WOT Box.
This being said, many successful installs have been made on Catalytic‐Converter equipped
vehicles. Damage usually is only caused by using the launch‐control feature for more than a
few seconds, but once again, USE AT YOUR OWN RISK IF YOU HAVE CATALYTIC CONVERTERS!
Please visit our website at http://www.n2mb.com for the latest version of the WOT Box
software and installation instructions.
Solder all joints. The N2MB recommended soldering method is available at
http://www.n2mb.com. Use a multimeter to verify all wires before they are cut or tapped
into. The colors of wires from model year to model year may differ, and may be different on
your car from those described in these instructions. Where discrepancies are known, they
are described, but there may be more discrepancies than those listed. The best way to know
that you have the right wire is to check the connectivity to the ECU and/or sensor at the pins
described.
In these instructions, pictures include other aftermarket alterations in addition to the WOT
Box. N2MB is not affiliated with these devices. In addition, if you see something that isn't in
your vehicle, don't worry.
Route wires in the manner that you want them to lie permanently before connecting them.
Cut wires to length before soldering; avoid coiling wires of excessive length as they can cause
noise in the circuit, altering the operation of the WOT Box. Spending some extra time here
will enhance the aesthetics of the install. Zip ties are included to secure the wires away from
heat, moving parts, sharp edges, or anything else that can damage the wires.

- Page 8 Troubleshooting ‐ Testing the WOT Box 1. Key on the car but do not start the engine. Press the gas pedal to the floor. You should see the LED on the WOT Box start to rapidly blink. If it does not, check your APP sensor signal connection (WOT Box BLUE wire). 2. Next, with the gas pedal still depressed, press the clutch pedal to the floor. You should see the LED on the WOT Box briefly go out, and then come back on solid for one second and then finally resume blinking rapidly. If you do not see this, check your Clutch Pedal Position Switch signal connection (WOT Box GREEN wire). 3. Next, start the engine. Quickly press the gas pedal to the floor and immediately step on the clutch. You should hear the engine start to rev up, stumble for a short period while the ignition is cut, then return back on and continue revving. Remove your foot from the gas before you hit the rev limiter. The 2‐step will not engage if the gas is depressed before the clutch. This is normal. If the engine does not stumble or pause when the LED turns out, then check the RED/ORANGE paired wire. Verify that the RED and ORANGE 16 AWG wires are wired facing the proper way. If they are reversed, the ignition cut will not work. 4. Lastly, test the 2‐Step. Press the clutch pedal down and then quickly press the gas pedal all the way down. The gas pedal must be floored for the 2‐step to engage. The engine should rev up to the desired RPM and hold. If it does not, be sure to remove your foot from the gas before you hit the rev limiter. If the 2‐step does not work, check the WOT Box YELLOW wire. 5. The WOT Box Graphical User Interface has some inherent troubleshooting capability. If you have access to a laptop, it may be useful for you to download the GUI at www.n2mb.com/wotboxsoftware and follow the instructions there. Usage To use the WOT Shift feature, keep your foot fully on the gas and shift quickly using the clutch. Keep the gas fully depressed through the shift. The WOT Box will detect the clutch switch signal and briefly cut the ignition to enable an effortless shift. To use the 2‐Step feature, fully depress the clutch. Next, fully depress the gas pedal to the floor. The engine will rev up and hold the RPM that you have set. Quickly release the clutch while leaving the gas fully depressed to launch the car. Programming The WOT Box comes preset for an automatic WOT Shift kill time. This means that the WOT Box will automatically adjust the kill time to your shift time, up to a maximum of 350 ms.

To confirm, the WOT Box will blink back out the setting you entered. The WOT Box comes preset for a 2‐step RPM of 4000. To set the 2‐Step RPM, repeat the same procedure described above, but keep the clutch down during the entire operation. This will signify to the WOT Box that you want to set the 2‐step RPM and not the WOT Shift kill time. Use the second chart provided below to match up the desired RPM with the number of blinks.
