Default Apexi Power FC and commander

Hey everybody.

I was givin an Apexi power FC with the commander for my 96 JDM EJ20g. After I install my motor(96 JDM EJ20g version 2 STI) in my car I'd like to use this but i havn't got a clue how one works. I tried searching for a manual for it but couldn't find anything for a subaru in english. Does anybody know where I can get some information on how these units work.

Another Question - when I do decide to add the Power FC to my car should I take it to a tuner shop and let them install it and tune the car.

You will at the very least need a base map and then calibrate the PowerFC for your car and its sensors, and then get a shop to protune it. Most shops won't touch them because they are too old and their tuners don't know how to use them and don't have the connectivity kits and software needed to tune them. At a minimum you will need a tuner with an official Apexi interface (doubt anyone has one, they are $$$$) or a Datalogit box with FC Edit software, or CoPilot software.

i would say you should sell it (theyre worth around $600-$700 with commander) and then get a tune on your stock ECU from Rob. It would be cheaper and youd maintain the benefits of the OEM ECU, like knock correction (which the PowerFC doesnt do)

The PowerFC is a very useful stand alone ECU. But like any ECU, its only as good as the person tuning it. If you do not have access to a tuner around you who knows how to program it, or if you can not figure it out. Your best bet is to get a off the shelf tuning solution such as a ECU reflash.

you can't flash tune a K with anything off the shelf.

you can try esl solutions op, but the interface is very suited towards tuners that know more than how to use simple interface (ie cobb, rom raider, utec). It's damn powerful.

IMHO, if you were truely given the PFC, then you should have budget to get the Datalogit setup (IIRC, about $400).

Once your set-up, any competent tuner (or yourself) should be able to tune it for you. It's all the same tables and principals as any other engine management.

The lack of active knock correction can be concerning for those who like to tune at the edge. Less of an issue for those who prefer conservative tunes.

OP, if you have any tuning experience at all the Datalogit software will be easy to figure out. I'm not sure if they still do it,but you use to be able to download the software for free to tinker around with it to see how it works.

Everyone that is concerned about the knock correction, but with the commander you can actually view your knock count. From the factory the PFC has a threshold that makes the "check engine" light flash if the knock count goes about the threshold.

One thing about the PFC tho..

It does not..I repeat It does NOT help control anything. It does exactly what you tell it to do. If you make an error it can cost you. The factory ECU will help you out by pulling timing if it detects to much knock.
