High Idle Mod
Are you trying to replace your tach? There are diesel tachs out there, or you could install a factory tach with a little work...
This is an AIC/ACPM Recent image by Roy_Thorne on Photobucket
Im not looking to replace the tach, I just like to use my AIC to keep an eye on my RPMs as its much accurate than the tach...plus it looks cool haha
I figured it couldn't be used to change the idle (since idi doesn't have many electronic components).
MY next question is is there a way it could be used to just read the idle?
First thing of all, where the hell does it plug in? IDI's don't have an OBD port.
Secondly, where does a powerstroke get its RPM signal from? I'm not positive, but don't they have a crank sensor to tell the computer when to fire off the injectors? The tach on an IDI is an afterthought. Its a decent system, but it works by counting the gear teeth on the IP gear. There might be a slim chance the powerstroke gets its crank/tach signal from something similar, but I doubt it will be plug and play without some more fancy electronics.
There are other aftermarket tach solutions. Some can work off of a signal from an alternator (sounds pretty wonky, but at least some older VW diesels did that). There are also photo-electric type sensors that work off light, or magnetic sensors (like the 7.3L idi uses) that can be rigged.

It doesnt work off the OBD port. There is a small plug right above where the shifter (if manual) would be...it just plugs right up. Its a circular plug a little larger than a nickel.
