psu_Crash Posted April 7, 2009 Report Share Posted April 7, 2009 (edited) The megamanual says that 91-93 Buick and 88-93 Chevy's came with an Idle Air Solenoid that I can use for fast idle with MS. Anyone know the specific model car/truck I should be looking for, and/or have any experience using one? Edited April 12, 2009 by psu_Crash Link to comment Share on other sites More sharing options...
Technology Posted April 7, 2009 Report Share Posted April 7, 2009 I'd just go junkyard diving if I were you. And then let me know how it goes because I need an idle control motor BAD. Also, you're going to have a PM in a minute here. Link to comment Share on other sites More sharing options...
psu_Crash Posted April 7, 2009 Author Report Share Posted April 7, 2009 Thursday morning I plan on going junkyard hunting. I'll let you know. Responded to your PM too Link to comment Share on other sites More sharing options...
psu_Crash Posted April 8, 2009 Author Report Share Posted April 8, 2009 At work last night I came up with this: http://img159.imageshack.us/img159/3928/solenoid002.jpg I think i should do the trick. Modified the 24V solenoid to operate at 12V. Now the only real question is will it flow enough to make a significant difference. The barb that will T into a manifold port is 1/8" NPT. Should be comparable to unhooking a vacuum line, which increases my idle plenty. Another question is if my MS Fidle circuit can sink or source 150mA to run this directly. Should go in for a test tomorow. I'll let you know Link to comment Share on other sites More sharing options...
Indiana Posted April 10, 2009 Report Share Posted April 10, 2009 http://www.diyautotune.com/catalog/custom-...valve-p-69.html and a jeep idle motor Its about 125.00 for both parts but it works. The hose comes from the back of the plenum with a 90 fitting, runs underneath and the motor/housing is fastened to the front of the intake on a bracket. The hose out goes to the intercooler pipe just in front of the throttlebody. Link to comment Share on other sites More sharing options...
psu_Crash Posted April 10, 2009 Author Report Share Posted April 10, 2009 (edited) $125 is what I am trying to avoid Indiana. I hooked my version up this morning and MS seems to control it perfect. When engaged it raises my idle by about 500 RPM. I put another barb where the filter is in the pic and routed it to the IC pipe in front of my TB. More testing will come tomorrow, but i think this is going to work just fine. Once i get things all mounted i will post some pics.

macrophage Posted April 10, 2009 Report Share Posted April 10, 2009 Crash is mad funny--he went straight to "industrial electronics" to get the job done -totally original i like that "Bead Filter" on there. Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted April 10, 2009 Report Share Posted April 10, 2009 Please post installed pics and possibly a part number and wiring diagram for this setup. I'm in need of an IAC and I don't want to spend more money for the same thing if I don't have to. This looks like it will work just fine. Thanks!

Indiana Posted April 11, 2009 Report Share Posted April 11, 2009 Well as long as it holds up to engine bay heat go for it. You can also use a idle air valve from a german car. It closes slowly as the motor warms up and there is only a switch to activate it. Link to comment Share on other sites More sharing options...

Thanks for the compliment. I am getting rid of the filter and routing a line from the IC piping to that port. That way there is a little pressure and it will flow better. Using that part is perfect for me. Free parts and rebuild kits if I need them. I love my job Indy, we use these valves at work on machines that melt and form glass, so i don't think heat is going to be an issue. As far as wiring, one of the 2 connections goes to my Fidle wire in megasquirt and the other to ground. Taking my intake off tomorrow for a new gasket so sometime mid week I should be able to get some pics up of the install. Actually though about using one of the old EGR solenoids too but it didn't flow enough to make a significant difference.
