Mustang Throttle Body and Idle Air Valve with Megasquirt

[quickkafer]

As the subject states, I'm running a Mustang TB with my MegaSquirt set up. It's been done a hundred times before, so I know it will work. But I'm looking at the asthetics of the engine compartment now. The Idle Air Valve is freakin huge and pretty ugly. Have any of the aftermarket companies come up with a smaller (compact) options to replace the stock Idle Air Valve? I assume that MegaSquirt wouldn't give a hoot whether it was a Ford part or a ACME Idle Air Valve... Am I correct?

UGLY!!!


I need something a bit smaller and not so long. Any ideas?

Looks go out the window when you can reach into the car and turn the ignition and the car fires in one second and idles like modern. I pulled my valve off of mine because it caused more issues than it solved. i designed my setup to look cool, but wish i had left more room for a proper valve.

If I can't find a smaller version in the aftermarket, I'll just have to clock the throttle body where that monstrocity (sp?) is sitting behind the TB and you won't see it so much.

Can you just use the port and remote-mount an idle solenoid of some sort?

To be honest, I have no idea. I'm going to have to re-educate myself on a lot of this EFI stuff because I have been away from it for 2 1/2 yrs.

I tried that, and it didnt work well enough. In order to port it i had to drill and tap 2 holes in the tb and 2 holes in the valve. They were all close to the right size for my 3/8npt tap when i started. So the holes were pretty big. I piped them with quick disconnect fittings and 3/8 nylon tube. The shorter the tube the faster the valve worked, but it was never fast enough. I just think that there was too much friction in the lines. The valve couldn't flow enough quickly enough to make a difference. I fought with it for a whole day, then i pulled it off, threw plugs into the newly tapped holes on the tb and called it a day.

I tried to do the same thing and the issue is simply that to flow enough air to work as an idle valve, you have to have large ports. This makes the valves large. Smaller valves flow less, plain and simple. Every little bit helps, but you will likely not reach your goal with a small valve.

Small line (looks like 3/16 line) is enough to bump the idle up a nice amount.

I've seen conversions where there is an adapter to a remote GM style one. Pics on google all over.
