hi all, i just installed a zex wet kit in my car, i also bought a summit racing digital rpm window switch, i got a standard automotive 4 pin relay to wire the zex box to the window switch, with it wired up i programmed my on rpm and off rpm but when it asked for pulse i am clueless, it goes from 1-6. i dont know what to set it to and cant seem to make the thing work, this is holding me back from getting it tuned any help would be appreciated! im also not sure if the rpm signal im wired into at the coil pack via the yellow wire with red stripe is low or high voltage.

on the relay i have wired this way

pin 87 is wired to the tps wire on the zex box

pin 30 runs to the tps (green wire on tb)

pin 86 is ran to arming switch (fusable linked 12v source)

pin 85 is ran to the low voltage input on the window switch.

i have cross referenced this wiring on two seperate, so to recap the question i have is what is the pulse supposed to be set to on this switch and is the signal feeding the coil low or high voltage? i assume its low if so im right there, but need to know pulse, thanks

 

Bump for this. Anyone use the summit window switch?

 

pin 85 should be ran to a switched ground on the rpm window unit. why are u callin it low voltage input?

ur problem is likely the pulse. Those rpm boxes are setup to work with 4,6,and 8 cylinder engines.

also u have to program the zex box too. you are going to have to prgram the zex box for what full throttle tps voltage is. Kinda hard to do when u have it setup so the motor has to be at a certain rpm and WOT.

I do use a rpm switch. I shoot my nitrous by flooring the car and pressing the mode button on my steering wheel. I have full control

 

Please look here at the white wire and yellow wire. It says low voltage. Is that wire not used?

85 should be ran to the purple wire

 

Will that controller work work without the tach signal changer?
