I am going to be using a throttle body from a Q45. It is a very large (90mm) throttle, and has some interesting features. One of them is an integrated fast idle feature. The way it works is that it has two adjustable contact points for idle adjustment. One is the standard arrangement for hot idle, it has the typical screw/locknut against the stationary housing. The other adjustment places the adjusting screw against a temperature controlled fast idle solenoid. The really cool thing is that the solenoid is temperature controlled, rather than being the traditional electrically activated solenoid. An integrated coolant passage warms the solenoid and causes the plunger to retract, thus allowing the throttle to close down slightly as the engine warms up. It really is a nice setup.

My question is since I have this feature, will there really be any need for the Fidle circuit to be employed? As far as I can tell the Fidle circuit is just for activation of a idle solenoid. Am I right here?
Are there any other concerns you guys can think of for using this arrangement? To me it seems that there will be just one less item to wire up, and one less relay to integrate.

Thanks for your input!

Talk about crazy i have the exact same throttle body on my ford guess we are both cheap asses, lol but yeah on the nissan it has the little small water lines running through it i used it on mine seems to work and I used the f idle output for the fan control works good. had to make an adapter for it to mount to my edelbock elbow but it wasn't but.

So does it work well? Any difficulties you had making this work?

Thanks!

no problems works great adapter was the hardest part, and i made a cable the length i needed from a lokar cable. Zane

I do like the TB a lot, and they are dirt cheap!

I have one question though, where to find a pigtail for it?

Thanks!

salvage - junk yard - ebay?
