]']Hey peeps

just wondering which is better  

i know that F con V can only be tuned by BD4's but

i want to know  

if tuned right.

which will be better?

F con V or PFC?

What would a second hand HKS FconV sell for ??

What is the difference between the two?

F-CON V is old, don't know many tuners even in Japan who will touch the F-CON V. Not to say it's a bad ECU just that every shop has already upgraded to the new software.

Hell I've even tried to sell my old unit on Yahoo for 1000yen and no one wants it. The best way I can only sell it is like a Mines ECU including the mods list.

F-CON SA/SZ and the F-CON V PRO are the current versions.

I think in terms of features FConV < PFC = FConVPro (or slightly better than)

I'd take the PFC in terms of ease of tuning. FCon limits you to a select few tuners.

You obviously know little about the F-CON units, the PFC has gone through revision as well.

I'll admit about the limited number of tuners in Aust for the HKS unit, but very different in Japan.

I run a F-Con SA sub-com (piggyback) with a slightly smaller 20X16 map compared to a PFC, a full-com (standalone) with a 20x20 map. Obviously a sub-com requires less messing around setting it up, just plug it into the harness. I also perfer having the factory ECU there for feedback, diagnostics and troubleshooting which you'd lose on a full-com setup. I've also compared the PFC back to back with the F-Con SA and V Pro and there are limitations to the PFC, but not that you would notice unless your chasing big HP. For one the small map is disappointing for a standalone. I'm better off with a HKS unit because once your familiar with the HKS tuning it's an easy upgrade to a F-Con V Pro (32x32 map). You won't need a F-Con V Pro unless you after 500ps+, but the F-Con SA can also be setup as a standalone if need be with additional sensors. You can buy the HKS navigator unit (English) for tuning without the software.

Horses for courses; your question doesn't have an exact answer. It lies in the location of the tuners, cost and the application (hp/kW/ps goals). PowerFC is great for ease-of-use and simplicity, whilst an F CON V PRO would be great if you needed the detail in your maps and such for higher hp figures.

Do a search on all the top powered tuning shops cars and you will find I would say 80-90% is all runing a F-Con, the (Motec of Japan) and the rest PFC and in house ECU...the F-CON wins hands down as the prefered ECU!!! Also if the shop has a HKS bit writer license they will always perfer tuning F-CON over any ECU.

You also know what HKS stands for don't you? Hasegawa, Kawasaki and Suzuki, the 3 owners but now just owned by Hasegawa. You also know how Apex and Trust came about don't you? Kawasaki and Suzuki split and created Apex and Trust, thought I forget who owns which now. The PFC is a spin off from the F-CON but not quite as good as the F-CON, but sure can still do the job. The Greddy e-manage was released to compete in the same sub-com market as the the F-CON SA/SZ but you'll know how good they are...when what you pay is what you get.

You also already answered your own question, as said Aust lacks the tuners for F-CON thus people most go for PFC. Again as said the PFC is fine for most people so I would suggest a PFC with all the available knowledge in Aust.

Edit: also F-CON has been around longer since 1989, back then known as the PFC F-CON. Note the name of the Apex PFC!

lol learn sumthing new everyday

thanks mate really good answer :cheers:

:cheers:

Your welcome...too much mis-information on the internet these days.

Especially when I hear people talk about different Japanese ECU. I'll bet they've never even play around with any of them, just hearing what his mate's sister's uncle's dog said...or have substantial experience with each of them.

cool i'm going for F con V pro then.

what's the diff between the Pro and the normal versions?

Before you do, ask yourself what power levels your after?

Talk to the tuners in Aust who can tune the F-CON, see their work with cars tuned running the F-CON. I'm not say they are no good just do your homework on tuning shops. A quick comparison of the mods on their car to a similar car tuned in Japan to see how experienced they are.

I had a F-CON V then upgraded to a F-CON SA, you may ask why not a V Pro. Because I wasn't after hugh HP and the SA was sufficent.

Remember the F-CON V only had a 8x8 map when released back in 1995. The SA is already a hugh upgrade and I wanted to keep the factory ECU in there. Think how difficult or good they were to get 600ps on the old unit.

But if you want to be different and start early with the HKS unit by all means go for it. By the time it becames common in Aust you'll have the experience, which is why I went for it. I made the most of my hands on experience with the years I had in Japan. Also helps when I know 3 of the 10 HKS licensed tuners in Kansai.

Explained earlier the difference is one is piggyback and the other is a standalone, different resolution. V PRO can run D-Jetro and has some additional functions for hardcore tuning. F-CON SA requires an additional sensor to run D-Jetro. F-CON SA and F-CON SZ are the same, SA stands for Super Autobacs version. There are no difference that I know of. I got a good deal, well because my business partner works and drives for Super Autobacs (see the R32 in my avatar).

Edit: Can someone also tell me what's this ease of tuning you all talk about with the PFC? Laptop or handheld? Again me think this comes down to the shallow reply that most have not tuned with a F-CON before. Though I will make one point of the F-CON Naviagtor, the screen while nice and compact is a little too small to show the full map. HKS has noted this and is addressing this problem on the next version. All my tuning is done with the laptop, but if you don't mind paying for the handheld it's nice to have for the quick odd settings and status feedback on the road.

You obviously know little about the F-CON units, the PFC has gone through revision as well.  

I'll admit about the limited number of tuners in Aust for the HKS unit, but very different in Japan.

Fair call. I'm not an expert on them both, but my comments are based on experience with having both tuned in Australia (I have a PFC and my brother has an FConV). When I say 'ease of tuning' I meant that if you have a PFC there's over 15 places in Sydney alone you can get it tuned at. But with the HKS unit there's only a handful across the country. Also my view was tempered by the fairly poor tuning job done by one of the local HKS tuners.

I'll acknowledge what you say about Japan the HKS ECU being so popular. From watching a few Video Option DVDs I've seen heaps more HKS F-Cons than Power FCs.

From what I've read (and what you said) we seem to agree though Evo_Lee:D

But like he says Danny - The F Con V Pro is the better unit, but your results are only going to be as good as your tuners capabilities.

Razorsharp, I wasn't intentionally having a direct stab at you.

You just happened to make the comment first what most people percieve.

I'd actually highly doubt anyone in Aust can still tune the F-CON V, as I said most shop in Japan wouldn't bother...where did I put that dam F-CON V software again!

You will find to tune a F-CON V over here is not that cheap, compared to a buddled package for the F-CON SZ including tuning. This is the move by HKS and the shop to upgrade customers over to the newer units. Bit of marketting also as the Navigator and the new products will only interface on the SZ and V Pro.

    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
