Default apex'i Power FC - who has used?

wondering a few things,

i know it will pull CEL's somtimes, but i am courious to know if it will sense octane differances and change settings so im not fubar if i come across a bad tank of gas, or if it will give me better settings if i stumble across a good tank of gas-

it will be tuned for 91 octane.

I think this belongs in the engine management forum.

The only way the ECU will know if you have bad gas is if the knock counts get too high, assuming you have a knock sensor

it technically does belong in engine management forum, but if you understood the premise of the question and the fitament on a Sti-RA Ej20 obd1 JDM only with COP ej20G, then you would also understand that NO ONE in the aftermarket management forum (bc all they do is bobb, pecutek, hydra,aem) has any clue of a PFC's operation.

i was actually hoping that duomaxwell would see this thread and chime in from experiance with the PFC because he is in the motherland.

yeah, I have been running one for about 2 years now. From what I can tell ya the power-fc will not change a thing when considering gas. It will not add or subtract fuel or timing. Its a stand alone with plug and play capabilities. What ever you do DONT run the car on the base map. I did when I got it just to make sure it worked and I had 189 counts of knock!

If you have certain questions this is the guy you want to get in contact with.

On a side note you might want to looking into getting the fc-datalogit, It will make tuning a crap load easier. Any mor questions let me know.

So is there a lot of power to be had from one of these things? I am also wondering if fuel economy would increase, cause mine sucks.

there can be, people in the US hate them cause they think there stuff is better. While it is a little outdated, people are still making more than enough power with them. I would say that above 50% of tuned wrx'x in the UK use power-fc's.

No it will not make adjustments as said in a previous post. It has base maps that are trivial at best. This is a set it and leave it stand alone ECU and make some fine tune adjustments when necessary. If you start running a better or worse gas you will have to make the adjustments yourself. As stated earlier the Datalogit is awsome and is definately a good thing to get if you plan on running your car the way it was ment to be run. With that said you can also by the software from Apexi now that will allow you to tune it with a laptop if you like.

can you save maps for different fuel and boost ect that you tune on the dataloggit, and then change it with the comander? or is the commander kinda useless?

I believe that it that sense teh commander is useless. The commander is used to make little adjustment, think of it as a afc with timing capabilities and to monitor settings. You could tune your car with it but it would take a grip. And I believe that in order for the datalogit to work you have to have the commander, but I might be wrong.

So,
this is plug and play for an early WRX ECU? What about a USDM leggy turbo one? If there any way around the COP issue?
