Description:
The MAF Variable Controller from Snow Performance represents the latest technology in Water/Methanol system control. The controller is designed to increase injection pressure over a user adjustable range and quickly shut off when air flow drops to prevent misfire. Designed for use with your stock 0-5 volts MAF. The small rugged design and easy setup makes the VC-MAF the logical choice for automotive/offroad enthusiast.

Operation:
Connect the output signal from MAF to input of controller. The user then sets two dials that are located under the lid of the controller. The first dial tells the controller what voltage to turn on and off. The second dial tells the controller the voltage where maximum injection is required. Once the two dials are set, the controller will linearly increase/decrease the injection pressure over the set range. Start voltage is adjustable from 1 to 5V. Full pressure is adjustable from 1.7 to 6v. Note that if the Full On dial is set below the Start setting, full injection pressure will occur once the Start voltage is reached.
