How do I wire in an AEM FIC?

[Cheezit033094]

Just picked up an AEM FIC with the harness. Does anyone have wiring diagrams for installation in a 90 tsi awd? Also, where can I get a USB cable for it? Can I just pick up one at Walmart?

Any USB A to B cable will work. A is the standard end you plug in to the PC, B is the big square end on the FIC.

Trying to find a wiring diagram for you, I swear I have something somewhere.

With the FIC not having an optical cas input, it worries me

yes it does. I've used AEM FIC on quite a few cars and tuning is easy and install is easy.

there is both cam and crank Hal or mag sensor pick-ups.

only bad part about the whole thing is it only retards timing, no advance.

OP once you have the aem fic installed, make sure to hook your laptop up to it and sync the rpm. ( hold 2k rpm, and sync witht the fic ) or it will never run right.

Which do I use for my optical cas? Hall or mag?

most likely it is a MAG sensor. since I don't know of many cars that had hall effects sensors in 1990.

I've been searching around and lots of people say they can't get it to work with their Dsms with an optical cas

The optical CAS outputs a signal similar to hall effect. The 1G used both hall and optical, depending on year, and either one is compatible with any 1G ecu.

It should work, although there's no real reason to use one, considering there are a bunch of better tuning options. DSMlink, for one.

If it is an Optical sensor, then it would be wired up just like a nissan RB engine, so use Halo / Hali sensors. and use cam not crank.

use google to see if you can find a diagram
