if the engine check light stays on it means a sensor is out of range, not working or giving incorrect values. when you see it on, look at ETC, SENSOR SW CHECK and look for any sensor names with a black background around its name. this indicates the fault sensor

if you enable the boost kit for enable and dont have the map sensor harness connected the engine check light will be on and BOST under SENSOR SW CHECK will be highlighted, indicating the boost map sensor isnt working or out of scope (ie: its not plugged in)

hey paulR33.

its ok to run the GTST with a PFC. but if ur only commuting will it be economical to run it with the stock ecu. i wont have time or money for a tune. so just wondering. is ther any real world figures. my GTR averages 12-15 p/100kms. what will a base map PFC on a GTST yeild?

thanks again

mark.

thats what i was thinking myself.

just like to say we all apprciate the write up and effort put into this PFC guide. its the best we could find on the net. and thanks for answering somewhat repetitive questions so promptly. your very appreciated mate.

thanks again

mark.

Just installed mine and can I say how much better the base maps over a the standard ECU. Teh car feels so much more reponsive now...shift from 3rd and 2nd and the thing just launches!!!

Now to get a tune........

  • 3 weeks later...

I was wondering if there was a way I could display my oil temp on the PFC. Maybe I could use the Air flow temp function to measure the oil temp via a sandwich plate? Do you know if this is possible Paul?

  • 4 weeks later...

added correct pfc boost kit port mappings (on the solenid)

added photos inside GTR-RB26 PFC

added photos inside APENG-RB20 PFC

added piggbacking the powerfc

added power fc pro launch control

Hi there paul, great job on the thread mate its damn helpful, ive just installed my PFC into my r33 GTST 2 days ago with the assistance of your information, the car feels a tad better than the factory computer, im saving to get a tune, hopefully with in the next couple of weeks

I've noticed on start up one of the two relays which are mounted behind where the computer sits, clicks about 4-5 times as soon as i turn the reds on and the hand controller flashes with the clicks.

It done the same thing the morning after the install while driving with the engine cold turning right out of my street it clicked 4-5 times and i nearly got stuck in the middle of the road, once it warms up it doesnt do it while driving, but will still do it on start up, and the hand controller works fine.

I've plugged the factory computer back in just to check if the clicking still occurs and it doesn't.

I also swapped the clicking relay with 3 other relays and they all done the same

The clicking of the relay really has me stumped i cant think what could cause it, but its definately related to the PFC, something is switching the relay on and off really quick, any help you could give me would be fabulous and appreciated

The car is not heavily modified just a full exhaust, FMIC, cold air intake, 10psi boost and a walbro 500hp fuel pump

The PFC was brand spankers in the box.

Thanx again.

I could be wrong with this but at least its a quick and simple check to do.

Check all of your fuses below the dash on the drivers side. Don't just check they are all ok, check they are all there. I attached the pic of the english translation of it. I was missing the electrics or engine control one.

Go through the PFC FAQ it has a section on problems with clicking relays

Just like to say, Great FAQ dude.

Once finding out that the R33 PFC's were being discontinued, i raced out and brought one today, just tuning now. Only paid $1500 so happy with that given the situation.

PS. Anyone looking for one? Maybe contact JJR, i got mine there and there were about 2 more and 1 2nd hand, although the new ones were apparently sold! But still waiting there for pickup

cheers again! :sleep:

fry is correct, i would start there and check what he has mentioned.

i have never heard or seen a PFC click 3 or 4 times before boot up and come online normally.

usually if you have clicking relays its toast and never works. am surprised it works

only thing i can think of is view SENSOR SW CHECK with the car on ACC and see what it does ?

i checked fuses in engine bay, cabin and boot, they are all good and can't find any missing

i assume power to the PFC should be well because the factory computer is A-1

is it faulty? i hope not but i need to sort this out because if it is i need to get it repaired under warantee which sux as its brand spankers and i paid 1500 for the damn thing

ive got it booked for a tune on thursday and i just hope they have seen this problem before and hopefully know how to fix it *fingers crossed*

will do what you said in the morning paul sounds a good idea

thanx for your replies guys :(

Just because the factory computer runs fine doesn't mean the Apexi will. My car with standard ECU was running fine without the fuse I mentioned, the apexi wouldn't work. The standard ECU's tend to be less fussy with some missing signals and weak power.

If all your fuses are there and fine you may need to start looking at your wiring.

Pin 58 (black with white stripe wire near bottom of harness i think) needs to have a good 12V going to it. Just unplug your ECU harness and check this with a multimeter.

While you are at it check pins 50 and 60 (2 black wires on the bottom of harness I think) and make sure they are good earths.

Thats a starting point.

good luck

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
