I just purchased an apexi power fc, commander, and obd1 harness. Looking at the optional boost control unit but $350 or so seems pretty steep for a boost controller. Has anyone used another boost controller with the fc or is it recommended to get the boost control kit to run w/ the pfc. The boost control unit I'm looking at also comes with a 3 bar map. Does the pfc require a 3 bar map to operate in itself? I only plan on running 9 psi until I fully build my b18c1, then was going to go with a 3 bar etc. What do you guys think? Thanks.

 

The PFC boost control kit uses the same solenoid as the AVC-R. The PFC can control boost but the AVC-R has way more options, like gear dependent boost settings.

The Apexi MAP sensor is overpriced, just get a GM 3 Bar.

 

recently i tuned a subaru wrx with an Power FC. it kind of sucks because you can't edit a big piece(like 5loadx5Rpm) of the fuel/ign map.
You have to edit everything seperate.

Just get a FC Datalogit

 

where can i download this software? how do you connect it to ecu

 

you have to pay for it, its about 350

I've mentioned this to other people who are considering the Power FC.

You cannot use a 3 bar map sensor with this system. IT WILL NOT WORK.

The boost kit is needed in order for the ECU to function because though you may not be using an AVC-R, you'll need the map sensors to plug into the unit. I'm currently using a Profec B Spec II boost controller w/ my Power FC, but the functions of boost must be accessed, and can ONLY be accessed w/ the boost option. It's not the solenoid that makes the boost kit. It's the sensor, cable, and activating the boost option in the system.

See, there's a boost cut defenser that is in the system (yes, even for the Honda) and you must increase the amount of max boost so that it won't cut out when you're close to the desired boost level.

KEEP YOUR ORIGINAL MAP SENSOR. The Power FC uses both sensors in order to smooth out the transition between boost, and off boost. So don't lose it..

YOU MUST USE FC DATALOGIT - otherwise you'll be like the guy w/ the WRX because you can't access all the tables that are needed to make tuning easier. You'll wind up taking over 10 hours to tune. When I had all the components, It took only 2 hours to tune everything from Injectors and millisecond time delay, to a 16psi tune at both partial street throttle, and WOT. No street tuning..

This system isn't for everyone. But it works FANTASTIC..

First, you can use whichever MAP sensor you like with the Power FC. And yes, you can use the GM 3 Bar MAP Sensor with the Power FC.

Only if you use the Apexi 3 Bar MAP sensor you will still need the original MAP sensor. (Stock = Off boost, Apexi = Boost)

Second, you can disable the Boost Control Kit in the Power FC and just use a AVCR. The AVCR comes with it's own MAP sensor. I'm not sure if you can use the AVCR MAP sensor with the Power FC, but you can use 2 different sensors for the Power FC and AVCR.

You don't have to buy the Boost Control Kit, you just need any MAP sensor that can read boost.

 

I dont know about you guys but I was running GM3bar map on my powerFC(i had it chipped out back in the days) I was just forunate to find a power exel tuner that knows what he's doing... SGP Racing.com

 

I was just planning on getting the greddy profec b spec 2 I think it is and run that instead of getting the boost control kit. I don't know anymore, might be easier to just get the kit to go with the whole deal. Anyone really had any problems adjusting the pfc for boost not using the control kit? I planned on just loading a base map and set up for my injectors on the pfc, then running the car down to the dyno and have it tuned with the datalogit software. I'm running this on an obd1 car as well using the conversion harness if that makes a difference. Thanks.

The Power FC is a Fuel Computer (FC) and as long as you don't enable the boost control kit in the settings it don't cares about boost.

It reads the value from whichever MAP sensor you like and calculates the injector timing.

I wouldn't use the Power FC to control boost.

here is a question....... I have the PFC with the commander and boost...... is it better to run a different boost controller like say a Turbosmart E-Boost?

If you made it work, great.. We've attempted several times to use it, and since we had the boost kit sensor with it, it was just That much easier to use that as opposed to trying to wire in a GM 3 bar map sensor. It was simple plug & Play at that point, and the ECU automatically allowed for the boost settings. I wasn't implying that I knew everything about the system, but from my experience with it in the U.S. Using the boost sensor w/ the kit was the easiest to do.

A lot of people are using the GM sensor with the Power FC. With the boost control kit you can only set a target boost and limit it by air and water temp.

With the AVC-R you can set the target boost by gear and RPM. Also the scramble boost (overboost) button you can use with AVC-R is nice.

Does the Power FC learn the duty cycle like the AVC-R?

The AVC-R is also nice to monitor boost etc.

The boost control kit is like $300 and the AVC-R $400, so i would recommend to get the AVC-R.

Does anyone know if the MAP sensor that comes with the AVC-R can be used with the Power FC? You could hook up the wires to the Power FC but i don't know how accurate the sensor is off boost (vacuum).

 

Interesting. With the Sensor kit that plugs directly into the ECU, as long as the boost control setting on the ECU is on, I've used about 3diffrent EBCs with it.

 

Sorry for my stupidity, but I can just use my stock map sensor if I run 9 psi for now without having to do a 3 bar map and all that for later correct? Thanks.

Not sure... It still uses the stock map sensor for off boost transition, but not sure if you can ONLY use the stock map sensor...
