Pfc Owners

I am looking to put a Link (Vipec) ecu in my (now manual) S1. There is an R34 plug-in model which i hope to use. Can people who have put a PFC (or a LINK/Vipec) for that matter - confrim that the firing order for the plugs and the injectors is the same? I believe the only changes are for the engine warning light coming on when there is no traction control? Do people still have fully functional Attesa (assuming they have awd in the first place!!)?

Thanks

Mine's running an R34 PowerFC - no idea about the firing order for spark plugs or injectors, but I think that some mods had to be made in regards to the voltage and/or signal sent to the triggering of the spark plugs, or vice-versa.

ATTESA works fine, no issues there!

From what i remember my S1 (Feb '97) R34 PFC mod was 2 injector wires around the wrong way & "The Secret Squirrel Tweak" which was all done inside the PFC and works

so 3 wires all up. But there are, (from what is on these forums) 3 ECUs for the S1. the last of the S1 ecu's was something like 10 or more wires.????

S2 is no issue with an R34 GT-t PowerFC, it starts and runs it fine but just the traction control (pin 51) needs attention to get rid of the check light.

I have the OV300 which is the earliest and most common S1 ecu. It would appear from the diagrams and pinouts that i have that the ignition signals are the same but the injector firing order is different - only 2 the same: Nos 1 and 3. I wish people would not talk about secret squirrals - surely the time for such coyness is past? I gather there needs to be some kind of resistor put in the wire which cones off pin 51 - anyone know what kind and what value?

hi guys, my Stagea S2 is auto not manual, there some Power Fc for sale on Ebay, for BNR34 or ER34 , which one is the right one for me? what is the part number ? 415-X001 ? 415-A001 ?

neither will suit. you can't put a Power FC into an auto stagea as the auto gearbox is controlled by the stock ecu. if you do your auto wont work.

For your S2 Nistune is the answer - cheaper too.

sorry, what you mean is i can't put Power FC for my S2 stagea is because my stagea is an AUTOMATIC gearbox? that's sad...if i knew it from the begining, i would get the Manual box...damn.

so the Nistune wil work on my AUTO Stagea right? how much is the Nistune? under AU$1000?

sure does, thats what myself and others are running in their S2 autos. its a daughterboard that is installed into the stock ecu that lets you tune the stock ecu's maps. so the auto controls are still there.

the daughter board itself around $450 from nistune then you need to get it installed (requires circuit board soldering), and then tuned. or, you can expect to pay around $800 for workshops that deal with nistune to supply, install, and tune. have a search of the forums, there are a few good nistune threads around that will contain more info on the product and which workshops can do it.

Thx guys , I will do that.
