Step 4: Hit the prime button on the VC-50 controller. The system should engage and fluid should be
atomized out of the nozzle.
Step 5: Enjoy increased octane! See tuning tips / FAQ at the end of these instructions for more info.
VC-50 Fault Alerts
Low Level Alert
• When the fluid in the reservoir is running low the border of the graph for injection will blink
yellow alerting the user to fill the water-methanol reservoir.
Clogged Line
• In the event of a clogged line the psi reading on the main screen will turn to stars and begin
flashing. If this occurs, fix the problem and press the middle red button to clear the code.
Broken Line
• In the event of a broken line the psi reading on the main screen will turn to stars and begin
flashing. If this occurs, fix the problem and press the middle red button to clear the code.
Solenoid Not Engaging (Dual Stage Systems Only)
• In the event of a solenoid not opening to engage a second stage of water-methanol the psi
reading on the main screen will turn to stars and begin flashing. If this occurs, fix the problem
and press the middle red button to clear the code.
Tuning Quick Reference
The power potential of the system is realized through increased boost and/or timing. The large gains on
octane and cooling provided by the system make this possible, even on standard pump fuel.
The Boost Cooler® adds an alternate fuel source as well as significantly cools combustion. With the
Boost Cooler®, one does not need to cool combustion with overly rich air/fuel ratios. To minimize
combustion quench, you should start with an air to fuel ratio of 12.0-12.5:1. Injecting water/methanol
lower than 3300-3500 RPM could result in combustion quench.
All vehicles are different. If the engine bogs or loses power, then injection is starting too early, the
quantity is too much, or there is not enough methanol in the mixture (50/50 water/methanol
recommended).
