uhh matt the link doesn't work.

custom gauge install huh? got any pics? I may go the route of turbo or may stay N/A to the extreme for more reliability... so either way i'll need to throw a gauge or two in and would like to see how you've done it.



BTW Jonathan-

A S-AFC is a Air/Fuel Mixture computer. (the S stands for "super" as there is a regular AFC by apex already. The difference between the two is the "super" has a really kewl looking display ) The "official" name is: Super Air Flow Converter

It's job basically is to allow you to adjust the (obviously) Air/Fuel Mixture ratio. I believe the Pre '99 SOHC 2.5L engine ran a bit rich with mods like intake & exhaust, even after reseting the ECU. And '99 and later ran leaner with the same. The S-AFC or AFC can adjust the voltage coming from the MAF/MAP/MAS whateva into fooling the ECU that there is less air or more air entering the intake. Thereby leaning or enrichening the Air/Fuel mixture being injected into the engine.

Here's a pic, courtesy of Kartboy! (thanks! )
