Re: two solenoids on one spike?

Quote:
The spike user guide on IFI explicitly describes how to control the functionality of two solenoids using a single spike relay.
The question was two double solenoids, which is really 4 solenoids.

Quote:
A reason Our team is doing it is to fire both transmissions at the same time with two small pistons on our Super Shifters.
That is what I thought. You do not need two double solenoids to achieve this. Just use one solenoid and use a T to send the air to both pistons. This will get you much better performance and you save the weight of the extra double solenoid. We have shifters and this is exactly how we are doing it.
