Well..all i know is that you have to get an aftermarket Tach..and then hook the SPI controller to the tack light......then you set the light to blink on at 3000 rpms...and then whenever you hit 3000 rpms..the light blinks on and it activates the SPI controller...and the SPI opens the Butterfly valves...but i dont know which wire you need to split and all...ask Jeffescort..he as already done this...as for me..im only planning to do it this summer havent checked everything yet...
but its cool cauz i had already thought about using a tach light to activate my valves on my custom intake runners..but then the project never came to life...neways..for now
Hope it helped a little
SOrry i cant do more hehehe
You will need a RPM switch to control the Split Port Motor (IMRC) because the 2nd gen PCM does not have a output to control it . When closed they help out with low end power, when open they add high end power. DO NOT remove the SPI plates or motor, they help with performance and the computer will not let the car idel right with the ports open all the time.
Works best to set SPI IMRC to open at about 3000 RPM's.
SPI Controller Options:
-MSD RPM window switch, requires pills for differant RPM settings.
-Summit's RPM switch for $45.00 http://store.summitracing.com/partdetai ... M%2D830449
- After market Tach with shift light output terminals. (wire relay to tach to power the motor) Then just set the shift light to what ever RPM you want them to open at.
To wire the SPI Controller:
Red/Green wire is positive, Brown is ground, the other two you dont need. The positive wire should be powered through a normal automotive relay to drive the IMRC motor. a A 1 to 3 ohm @ 25 watt resister should be used inline with the motor and relay to keep the motor from over heating and stripping gears. 1 ohm will take it about 1 seconds to open, 3 ohm will take it about 3 second to open.
UPDATE........come to find out that the imrc does not have the clip with the wires in it.........meaning theres no power wire or any other wire in my imrc the clip is not there......so now wat would i do?? how would i hook sumtin up??
I'm really suprised the junk yard took the time to unplug it, usally thay just jake a huge cutter and cut the harness from the car leaving all the plugs on the sensor.
You should beable to go to Radio Shack and find a slide on connector simular to a speaker crimp cenector but smaller to slide on to the IMRC plug pin's.
I'll have to double check the pin out to know what pin's to use.
