Hey Guys, Ive finaly finished putting together my build and now need to set the PFC so i can get it to the tune shop. ive never played with a PFC before and to be honest a little scard to touch the hand controller lol

Ok its a R33 S2 GTSt and ive done:

Z32 AFM

Sard 555cc Injectors (denso 195500 2240)

Hiflow stock turbo

Tomi Pon cams

Greddy Profec b boost controller (run 10psi atm)

FMIC

Any Help would be much appreciated

Thanks, Dave

Basically to get it running to get to the tuner youll just need to select z32 afm and also set ur injector vaules which from memory for 555 it would 0.67 and .18 latency but check to be sure. Have a look at pauls faq for details how to do this all.

no matter what you do

run minimum boost

dont load it up

dont flog it

simple

with the basic z32 set and injector settings set correctly and default maps you should be ok

if in doubt, richen it up a little as an insurance policy

if you flog it, boost it up, trash it

expect it to go bang as you have changed quiet a bit

.18 is for the nismo 555s, sard/denso will be different.

as said though, select vg30 from the airflow list and scale the injectors to 67%. do a search around here and check pauls faq to see if you can find the latency figures for your injectors.

The ignition timing in the standard pfc (not tuned) is too much for 98 ron fuel. It will knock like hell. However it is not that hard to sort out and I'm sure you could fix it up with a bit of help. I have an ign map that you can put in and it will be fine. It works on my car with a stock turbo and I can run it up to and over 16psi without any significant knock. It has been proven on a dyno after I tuned it. However as your turbo will be putting out a lot more air than mine I would suggest that you pull 2 degrees on the temporary ign adjust and run it like that to guarantee no knock. Then when you know there is no knock leave it as is. Bear in mind that the temp ign adjustment will be reset every time you turn off the car. I can help you with the ignition timing but the fuel is not something that can be done over the phone or the internet. Luckily the power fc is rich as crap when untuned so you should be ok. BUT you have to get a wideband and check it BEFORE you flog it. Like it has been mentioned you car can go 'bang' very quickly if it runs lean and you are giving it shit for an extended period. You could break it in under a minute given the right conditions. To summarize, I'd repeat what Paul said. I'd also say put in the ign tune that I'll pm you (If you like) and then drive it to the tuner immediately to get it tuned. Cos the ign side will be mostly done, it will cost a lot less to get tuned. Read the pfc faq and make sure you set the idle up right. Hmmm...thats about it.

If the PFC is not brand new then it may have a tune on it. Init data first to ensure any old tunes are gone. Then setup the injector settings and set it to the correct AFM. Then what I would do is pull 5 degrees of timing across the whole map. Settings and then in ignition and set adjust to -5. Car will run like shit but should be safe enough to get to the tuner. Ive experienced a stock power fc on a stock car and flogging it lol. Det heaven.

Yes that is a good point. There probably is a tune on it already. In the pfc faq you will find everything you need to set up the injectors and afm. Just read. Although pulling 5 degrees across the board would keep knock away I think it is a bit drastic. Some areas actually need 5 degrees added to them.

isnt there a setting on the power fc that if turnt on and the car knocks, it makes the engine light flash

ive had that happen on mine one time..

yes, by default it flashes the engine light if knock exceeds 60, injector duty exceeds 98% or afm voltage gets close to maxxed. all 3 have a different type of flash.

Pfft. Dont be scared mate. You can plug it in and do the 30 minute idle setup, the afm change and the injector change and then drive it to the tuners. Simple as that. All blokes here are saying is that you could hurt it if you flog it untuned. When you reset the pfc it still has a tune in it but it isn't optimal. It wont blow up driving it there as long as you don't floor it. And as for putting it on a truck and towing it there that is a bunch of bullshit. I've pm'd you my number to talk you through the afm and injector changes you need to make. It really is a piece of cake when you know what to do.

ok so i have now setup the PFC with thanks too Nathan (Room 42) for like an hour of his time

injectors 66% latency .034

VG30 AFM From the menu

did the 30min run a/c on ect. but it rough as guts and seems to me like its only running on 5 cylinders. gave it a little slow poke to 2000 rpm and there was no change up to 2000rpm. a mate sugested that it may be the AFM but i get a reading on the pfc

PFC displays this :

InjDuty 2 %

IngTmng 17 deg

Airflow 1415 mV

Eng.Rev 890rpm

BatVolt 14.2

Knock |

Wtr Temp 48'

also i had the injectors tested before i installed.

Yeah running very nice ans smove now turns out the wires came out on the 6th injector. i can do amazing things when i actually open my eyes. :P

so now i wanna reset the PFC and do the cold start run again. do i just disconnect the battery and push the break or do i need to reset the PFC somehow????

Hey man cold start is different than the 30 min idle learn that you do first off. To reset you go into etc and its in there somewhere. You initialize the pfc. Unplugging will do nothing. Then you will have to put in the vg80 afm setting, the injector settings and then start it and do the 30 min idle thing. I have got away with not doing the idle thing and it makes bugger all difference. Up to you. I cant say it enough tho man as tempting as it may be dont give it a hiding until its tuned. I've pm'd you the ign map.

Cold start is setting the water temp in the settings. You add or subtract fuel by increasing or decreasing the numbers in there. As it isn't tuned the numbers already there will do the trick for now. When its tuned ideally you dont want any numbers in 50 or 80 degrees so the tune stays more stable. Dont make it zero yet as you will have to change the fuel map significantly to compensate for this.

the standard pfc cold enrichment figures are spot on, dont touch them. the only reason you should ever set the 50 degrees value to 1.000 (you have to have numbers in there...) is if your full running temp is significantly less than 80 degrees, which is pretty rare.

Mine runs at 70 degrees. Sometime gets to 75 in traffic. So my 50 and 80 are 1.000. When I say zero I mean 1.000 cos there is zero correction.

    • I'm selling my personal race car. 1992 BNR32 Skyline GT-R About eight years ago the engine developed the dreaded low oil pressure problem. I removed it and found the issue. However shortly after I moved half way across the country, moved my work shop, bought a house, got married, then moved my shop again to it's permanent location for the time being. in turn I do not have the time to race this car as it should be. In turn the engine I built for this car will end up in my street car and this car I hope finds a home with someone who can use it to it's full potential. The roll bar was built by Jason Noren Fabricaiton in Pomona California to SCCA and NASA Specs. The car used to compete in redline time attack and global time attack enthusiast class. It also has a fire suppression system.  The car is with me at my workshop in Kyle Texas, USA. Shipping it is no problem, I can personally deliver the car to the port of either Houston or Los Angeles. Any other port depending on where it is may require transport but we can always work that out.   The chassis itself is rust free, rear quarters and under fenders are free of any rust so it's a very solid foundation for anyone who wishes to move forward with it. As posted and at the asking price of $20,000 USD the car includes all of the following;   All OEM Body panels, front fenders, rear bumpers etc.  OEM Nissan Projector headlamps (Pictured N1 lamps were removed) OEM Nismo Side Skirts / Extensions OEM Rear Spats  Front & Rear Subframes are installed car is full roller Rear Subframe has Cusco Camber Arms, Whiteline HICAS Elimination Front Subframe has Whiteline tension rods and whiteline Sway bars w/ endlinks.  Buddy Club N1 Coilovers All chassis wiring and engine wiring is in tact. Attessa System is fully in tact and was functional before engine removal.  BCNR33 GT-R Brembo Brakes F+R with Endless MX72 Plus Pads, DBA Rotors & Stainless Steel Brake lines Billion Racing Radiator Billion Radiator Hoses Fluidyne Engine Oil Cooler Accusump System (trunk Mounted) 5 Speed Transmission w/ Transfer Case F+R Prop-shafts Rear Differential With rear Axles.  Nismo Gauge Cluster Nismo Clutch + Flywheel   Essentially what is needed to make this car running and driving again is as follows: A working Engine, an ECU, and time to put it together. The price posted is or best offer as I am willing to remove some components to accommodate price to a certain extent. If any serious buyer wants full detailed pictures, videos, or any questions I'll be happy to answer them. I believe this car is priced to move quickly considering it's a rust free and very straight chassis but always open to fair negotiation.  I can be contacted via phone or email.

    • So...to my (and my mechanics doing the swap) surprise...the oil pan from NEO engine does not fit 100% and needs to by modified like this: It is not a huge problem but in the future i want a "proper" oil pan. So question is...what different oil pan can i get to fit without any problems and modification? Thanks! 
    • Some more info I found.  These are the last entries Yoshikiyo Fujii made on his blog before he passed away in 2009: http://blog.livedoor.jp/fujii_dynamics/ And finally this is where the workshop was situated:  https://maps.app.goo.gl/HhTPtHzt3WVcBTiEA  
    • shit boxes, kids, and daily drivers are all welcome
    • Cam seals go hard. It's a very old car.
