looking to buy an f-conv (not pro). im in Japan at the moment but i cant find anything about them. the guy who is selling it says its easy to tune but i dont know if it needs software(like the pro) or what the perameters are or what functions it has. its cheap and it is pre programed for my gts4 so im really keen to find out

more. it comes with a book which i shouldnt have any troubles getting translated, but soft ware? hand set? minimal japanese cant ask these questions!

any help apreciated.

I the situation that you install in in an R33 or R34, I believe it operates as a piggyback computer. The tune can vary plus or minus 7 percent (stock ecu variation) and is therefore a waste of money and time, may as well have one of those shitty safc's in there... That said it will modify ignition timing but as I said it will vary due to the stock ecu making variations.

hey all,

I've got one of these pfc f-con thingys to which i bought a while back, all these things are a bit confusing as ppl keep thinking its a power fc which bought, well all mine says on the cover is pfc f-con and says it is a programmed fuel computer system, there doesnt seem to be anything where a hand controller can be pluged into, its is a piggy back computer. Does this computer simply over ride the factory pre set fuel map and compensate accordingly to modifications made to the engine such as afm enlargement?

F Con V has extremely limited support in Australia. There are only two or three tuners I know of in Australia for it (CRD, BD4s).

For that reason alone I'd go something that is accessible by most tuners (eg SAFC, PFC with handcontroller, etc)

,24 Jan 2006, 09:05 PM]so is the pfc f-con programmable or is it pre programmed? as i said , there is no where for a controller or lap top to plug into, does it need to be pulled apart

The Pfc f-con is before the f-conv. you can get a thing called a HKS gcc to plug into it to further control fuel over the rev range. Stick HKS gcc in a google search. From what i understand of this one (the pfc) it blocks a few unwanted signals from the standard computer and increases fuel plus changes timing for increased boost specifically programed for that model of car. the gcc gives an element of customisation but is not so difficult to use, dont know where it plugs into but they are advetised a bit. if you have a a\f meter and understand how a computer works you can do teh fine tune yourself it a general interpolated ajustment to teh fuel curve between seven points on the rev range simular to the fuel ajustment function on the preprogramed microtech, but with more interpolation, some people only spin second and third hand info (not helpful guys!). saw some sites where rally cars were using them and were impressed. They are also still popular here in japan.

Still cant find info on the f-con v ! (not pro!!!)

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
