Power FC Boost Controllers

[Waldo]

hey guys...just wondering what boost controller people use with the r32 rb20det power fc...should i use the electronic power fc boost controller...atm i have a turbosmart manual one..can i still use this boost controller or is it better off going with a differant one...

regards luke

[Wazz]

internal or external gate? IF external wat brand wastegate?

[Waldo]

my turbo has internal gate

Jaycar IEBC if you can read intructions and solder components onto a ciruit board. I have one on the Stagea and it works fantastic. Alternative, Power FC Boost Control Kit, I have one on the R32GTST and it works very well.

how do you hook up one on the r32 is it fairly simple like plug it in cut a few vaccum lines and stuff like that...like if i buy one does it come with installation instructions on how to wire it to my r32 or will it have instructions for any car

The R32GTST is quite different because the Power FC was made by AP Engineering, not Apexi themselves. It is a bit of a hybrid Power FC with some features found on the GTR Power FC's. Plus the R32GTST has a map sensor standard, with input to the Power FC (R33GTST's don't).

So when you get the Boost Control Kit it will come with a map sensor that you don't have to use. The boost control solenoid is simply wired into the outputs of the Power FC. When you have it, PM me and I will give you the pin outs.

I've got one running on my R32, works well. Usually run between 1.15 and 1.35 bar, it controls it quite well.

wiring is quite simple, not hard at all

SK, what do you mean about not having to run the PFC map sensor? Mine is wired in with the map sensor as well. It seems to work fine though

[Waldo]

ok because i have my power fc just sitting on my desk..i just need a few more parts before i get it tuned...ok so if i buy a power fc boost control kit, is there a specific one for the r32gts-t is there.. and i dont understand what u are talking about a map sensor..i just want to run my air flow meter...also just wanted to know about boost spiking with the kit..has it ever happend to you guys.....on the side of my power fc i have a ps/2 socket and another 3 pin socket...what is the 3 pin one used for is this the boost control input???

The R32's have a map sensor standard to run the boost gauge (same as an R33) but they also input that map sensor output to the ECU (R33's don't). So you can use the standard map sensor to monitor the boost and use the PFC BCK solenoid to control the boost.

How did you wire your PFC BCK up?

[Waldo]

where the map sensor is that the little black box on the drivers side firewall

[Waldo]

ok just read through it a few more times cos i wasnt quite getting the picture...so when i get one of these kits, i wire the solenoid in to the actuator, but then in the kit it comes with a map sensor which is needed for the information to be sent to the power fc (am i on the right track) but because the r32gts-t's have a map sensor standard that runs to the ecu already, that mean i dont have to run the new map sensor to the power fc right?? is there any wiring involved in using the existing map sensor or does it just remain untouched i just wire up the solenoid and whatever else is needed to control the solenoid..is this how it works on r32's

With mine, the Map sensor had a 3 wire plug that went into the PFC, the solenoid had a red and black wire, I wired 12V to the red wire, and the earth wire plugged into the Boost Control. I got the instructions from someone who wishes to remain nameless because of class rules meaning they cant run a EBC Has worked fine for the last year

So you reckon I could get rid of the PFC map sensor and it would still work?

No spiking on mine, but it does drop of a few PSI up top, but more turbo running out than anything

Sorry what does this mean, "and the earth wire plugged into the Boost Control"?

[Chris32]

sorry, should have been more specific. Plugged into the boost control pin on the ECU

Ok, so you have done exactly the same as what I have done, except you are using the BKC map sensor and I am using the standard R32GTST map sensor. I suspect that the BKC map sensor may be a 2/2.5 bar one, which may be necessary for people running boost that high. We run less than 1.5 bar, so I have never had a problem.

[Chris32]

Ok, you had me worried mine was wrong!

So will it work if the PFC map sensor isn't plugged into the PFC?

Mine does, but I haven't tried using the BKC MAP sensor, might have a go at it one day to see if there is any difference. Do you notice any difference between what your standard boost gauge says and the PFC Commander display?

[Chris32]

Interesting.

To be honest, I have never compared the two directly, might see what they compare like on the way home, I will let you know. I have seen 1.6 bar on my hand controller peak hold, so I don't know how much to stock sensor would read up to?

I would say, just being a sensor, it would read whatever the actual pressure is, there would be no point in Nissan putting a sensor in that is limited, it would probably cost more!

Very interesting though, I wonder what else is in those ECU's that we dont know about!!

Sorry guys just an interuption, ive got the Power FC Boost Control kit but i seem to missing one bit. I think its the Manifold Pressure Sensor. They are expensive from APEXI, about $200, can i buy a bosch one or something?

Cheers

Post up a picture of what you have got and we can tell you what is missing.
