when should the water be injected??

[mr2j]

Hi ive just fitted aquamist to my MR2 and was wondering what boost level i should have the system activate at..
Currently the car is running 14psi and the water is activated at the factory set 10psi......
also.... which way do i turn the screw on the pressure switch to alter the activation point :? :?
any idea's welcome :smile:

I don't know which way you turn the screw, but I think you'll just have to test around and see what boost level for activation works best for your set-up.

You're probably in the right area right now with the trigger at 10psi.

You can install an LED across the terminals of the pressure switch mate. The activation point will be obvious then.

From the factory preset point of 10psi, 1/4T clockwise will increase the triggering point by 2.5-3psi. Reverse effect when rotatng anti-clockwse.
