Tuning is handled via a Palm Pilot, which is included in the kit with the Venom software pre-installed. The set-up screen is the first step. The user selects the number of cylinders, type of ignition system and then a Throttle Position Sensor calibration value is entered.

In Drag Mode, only engine speed is programmed. When you hit the prescribed engine speed and WOT is detected, the VCN-2000 delivers the maximum nitrous programmed in this mode. Cut-off happens only after TPS is less than 100 percent or engine speed falls below the activation point.

The kit includes two floppy discs for those who want to tune the VCN-2000 on a laptop computer.
Drag Mode
Drag Mode takes it for granted that you will be operating at wide open throttle so the only two tuning parameters are activation rpm and nitrous percentage. Once you hit the programmed engine speed and the hammer is down to the tune of 100 percent, the laughing gas flows. Nitrous ceases only after TPS is less than 100 percent or engine speed falls below the activation point.
Timed Mode
This strategy is similar to Linear Mode but you get all the nitrous programmed in the system when the two tuning parameters, activation rpm and throttle percentage, are met. The user can also program how long the nitrous flows. Not a bad idea; in the heat of battle, you can get carried away, and pistons and valves can cook because of it. Venom doesn't recommend pumping the juice for more than 15 seconds and there should be ample cool-down time between blasts. In fact, 15 seconds is the maximum setting at which the software can be programmed.
Download
The final screen downloads the setting to the VCN-2000 module. If you make changes to the program and don't want to download it, the settings can be saved in the Palm Pilot for later use.
Conclusion
The Venom VCN-2000 is in the high-price range, but its three-headed tuning strategy makes it an ideal choice for traction-challenged front-drive cars and vehicles that will see the strip occasionally. Venom uses the best quality components and puts the power of tuning right in the palm of your hands.

Here is where the programming is downloaded to the Nitrous Management Module. You can elect not to download and save the tuning inputs for later use.
Linear Mode uses two tuning...
Linear Mode uses two tuning parameters (rpm, TPS percentage) to dictate when nitrous is introduced. The maximum amount of nitrous is programmed at this point as well. When the parameters are met, the nitrous flows in a linear fashion, starting with very little and climbing as the TPS percentage goes up, with 100 percent of the flow realized at 100-percent WOT.

Here we see the Timed Mode screen. The programmed parameters are the same as Linear Mode but here you get it all at once. You can program how long the system will spray. For safety reasons, 15 seconds is the maximum setting the software will allow.
