I was wondering the same thing.
FIDLE is the acronym for fast idle.

It's actually just a damn EGR valve that opens and closes based on IAT when initially starting the car cold. (So in essence, it's a controlled vacuum leak)

The MAP sensor still meters the air as the EGR solenoid is ported off of a block off plate in the TB, where the PWM valve would've went. It opens on cold start up, lets in additional air, the MAP sensor corrects to add fuel, engine runs faster until it reaches whatever temp it's set to close at,....da-done-da.

You're still planning on using the Megasquirt setup, right?
 
Believe me I already tried talking him into a set of mls gaskets like right now lol! But I can only do as asked, any aftermarket block build should get mls or copper gaskets in my opinion... no one with a good block ever stops at 14-15lbs!! The timing will depend on what we get away with on the plug if it needs less it will get less if it wants more and still looks clean so be it!

I am assuming thats what it will run in general since thats what we're tuning with, with a full tank it should be good for a few hundred miles of cruising I wouldnt consider that useless at all. For just driving or low boost he could always run pump anyway but to each their own if you can afford to run good gas I dont see why you wouldnt.
