Faq: Apexi Powerfc - Frequently Asked Questions

[Proximity Motorsport]

Hello,

As i have stated befor i have rb20det with a ecr33 gtr power fc d-jetro

Now i just ordered a boost control kit for the fc. As far as i can understand from reading the boost control solenoid has a plug on it, which a cable plugs in and that cable must goto a standard boost control solenoid. Well the rb20det does not have one?? What can i do. Where should i plug this in or splice it in. I have checked most plugs in engine bay and none suit this plug. Pic is attatched.

PS. the extra map sensor they gave me aswell as the extra cable.... should i just keep as spares.. cause im assuming you dont run 3 map sensors on a single turbo engine!

hi leon,

the ECR33 and BCNR33 powerfc have a 3 pin boost control kit port on the side of the PFC

this is for the map sensor for the boost control kit (do NOT mix this up with the djetro map sensors).

the boost solenoid gets power from the existing wastegate solenoid wiring which is used with the stock ecu.

from memory the ECR33 and BCNR33 had this on the wiring loom as "wastegate solenoid" but the RB20 loom i don't think has this wiring.

If it does then you connect the solenoid to this "wastegate solenoid" wire and the ground to chassis ground.

If your RB20 loom doesn't have this wire then you will need to run it yourself. The power wire nees to run the ECR33/BCNR33 PFC wiring socket on the actual PFC - check out the wiring diagrams to find out what PIN # it is on the PFC and then get ground from chassis ground.

The boost solenoid uses a 12v power and switched ground to turn it on and off - so you can't get it wrong, if you do it just won't work

thanks alot... i half get that, i think ill wait for the_mafia aka pacey to help me out this wkend, but this should certainly be of help.

Just one thing though... were does the map sensors goto now? Do they have to be spliced in with the boost controller map sensor?

[paulr33]

i dont know - ive never setup a djetro PFC but i think it should come from the plenum

and i think the boost signal should come from as close to the turbo outlet as possible

Is there somewhere that tells us the "normal" range for sensors? I have been looking through the FAQ and cant find anything.

My car just started hunting badly all of a sudden and idles at 2000rpm when cold, 1500rpm when warm

A/C on or thermo fans on seems to stabilise hunting a bit.

I cleaned AFM, cleaned AAC valve out and then I checked sensors in the PFC hand controller

AFM sensor goes from about 1.3V (idle) to 2.4V at about 3000rpm (stationary)

Air Flow is about 1400mV if I turn that on with the monitor function.

O2 sensor is at around the 1.0V mark too and when hunting ranges from 2.72V to 4V

I replaced the fuel filter a few days before the problem started and it was really dirty would this be a possible problem?

I also went through a big puddle of water and the car stuttered...

Thanks

the nissan ECR33 service manual should tell you the voltage range of the sensor - check out the sections covering consult diag - it shows you how to do each diag and what the ranges should be - of course you can't do consult diag but it will give you an idea of what acceptable levels are.

the 02-1 sensor shouldnt go past 1.0v its a slow and narrow sensor, it should only go between 0.0v and 1.0v

any sensor that is out of range will be highlighted with a black background in the ETC, SENSOR SW/CHECK screen and the engine check light will also be on (orange engine icon) on the cluster

hey mate,

Me and pace got my car (rb20det djetro) up and running on satrurday arvo. Just one problem. Sensor check is coming up error with TPS sensor, We tested the tps with multimeter and it works fine. Do i need an rb26 one?? or whats the go there... the check engine light is on 24/7

Paul,

My mechanic says there's a difference between PFC's made for the R333 GTST S1 and the S2! One designed for internal ignitors, the other for external (can't remember which he said is which). He's going to find out for me today. The PFC I have came off a S1 and mine is an S2....

hi,

this has been done to death and covered a dozen times

there is no difference between S1 and S2 - the ignitor differences are on the engine side, not ECU side

so S1 ECU can be used on S2 and vice versa

There is no PFC for S1 and a seperate PFC for S2

Whats the difference between R33 RB25DET and RB25DET NEO R34 PFC?

Whats the difference between R33 RB25DET and RB25DET NEO R34 PFC?

quiet a lot

there NEO has some extra sensors, controls and features

things like traction control etc make it in-compatible to a std RB25

i suspect you could piggyback / hack out those items

Whoops, sorry Paul! Thanks.

Thanks Paul - I was just curious

Another question - whats the easiest way to knock some timing off with Power FC?

I found 2 options but both are as confusing as each other

SETTING -> INJ/IGN Adjust

Press DOWN 3 times and you will see -3 for IGN ADJUST.

This drops the IGN map 3 degrees timing temporary (will reset when car is powered off).

check the pinout for the TPS on the RB26 loom and compare it to the RB20

[nissan200sx.dk]

HI.

Great FAQ!

But is it possible to get some more info on all the different settings? Not maps, revs etc... But the stuff in "settings 2 and 4" in the FC edit program...

what effect they have and more on what they do. Right now im still a little afraid to begin playing with these settings.

[paulr33]

added some more info and topic discussion on gtr.co.uk on the powerfc pro

added d1 limited edition hand controller photo & info

[paulr33]

added some pictures for injector size changes

[paulr33]

update today

updated some text on the other versions and version matrix

removed some of the junk in the menu roadmap

removed some of the rare crap in menu tree

fixed up the formatting so its paginated now (easier to read)
