If i wanted to be able to electronically lift the idle of an EJ22 motor to around 1000rpm by a flick of a switch how would i go about this??

 

Ideas... suggections..

 

Thanks

messing with the IAC is tricky

 

One method would be to introduce a small filtered vacuum leak using a solenoid valve

(the ECU may try to compensate though)

 

I'd use an "idle up solenoid" from an

EA81 that has AC

 

Mount it as to hold the throttle open a little bit when

your foot is not on the peddle.

 

Or maybe if the car has AC, use your switch to disconnect the

compressor's mag clutch and turn on the AC.

Test this by unplugging the clutch and turning on the AC.

Sometimes the PS pumps have a pressure switch, one of the things I think it does is bump up the rpms if there is enough load on the PS pump. If you have that maybe you could wire into it to cause the idle bump up whenever you want.

Thinking of one of my ej22 throttle bodies in my storage. There is a screw on the top of them. On some cars I've dealt with in the past yo could turn this and raise the idle up some without ever having to touch the IAC. I'll try to remember to take a picture for reference tomorrow. Its late here, lol

As said elsewhere the cruise actuater/solnoid or whatever its called..I,ve seen this in action you can set it to what you want.Going to a club meet tonight if the guy who's done it is there i get all the details.
