Many customers with our stage 2 or higher turbo kits have wanted the ability to turn methanol on/off with a switch rather than have their car automatically use it when it's needed. This allows a customer to drive full throttle without methanol being used and then flip a switch when they want more power. This conserves methanol and allows them to ensure they always have methanol in their tank.
We originally gave our customers a schematic that allowed them to wire in their own switch. This design turned the methanol pump off and told the EMS that methanol was not to be used. This wiring schematic did not turn off the methanol fogger however and ultimately when the customer would go to use methanol again it would sputter and the methanol line would need to be purged before a clean pull could be done. We also had several customers mis-wire something which resulted in HPF support to get their cars fixed.
After using and testing all the switches that customers put in their M3's and dealing with the wiring issues, we decided to create a switch that was entirely plug-n-play, durable, easy to see whether it was on or off and simple to install. One that was shielded, the right length, and had the switch labeled. This new switch also turns off the methanol fogger nozzle so no purging is required when the switch is turned back on.
