Does anyone know anything about the hks f-con? It is not a true stand alone system so what would the restrictions be, as far as what mods you could perform? It seems as though you would be able to exceed its capabilities fairly quickly, and its not exactly cheap.

 

Depends on what F-Con you are talking about. PFC F-CON or F-Con V Pro. The PFC is an old piggy back type. The V Pro can be used as a standalone, but most people leave the factory ecu to run accessories, as that all it doing once the V Pro is hooked up. There is almost no limitation as to what you could run with the V Pro, but the PFC is very limited, as you stated.

Thanks for the response, I was talking about the PFC. How extreme could you take your tuning before surpassing its parameters(i.e. turbo upgrades, intercooler ect.) do you know? I was touring their site and saw a couple chip upgrades for the PFC, one of them did list turbo and intercooler upgrades but I was curious how reliable it would be(I know a guy who will sell me one for fairly cheap, thats why I'm so curious.)

 

You cannot mod the vehicle a lot if using the older PFC F-CON.&nbsp There are chips that are programmable (from HKS) that allow you to use large fuel injectors, different turbos, etc.&nbsp For example, the FC applications are for stock turbo and for HKS sport turbo upgrade - that's it.&nbsp It is very limited in terms of upgradability.&nbsp The GCC adds a little flexibliy to the system, but you're still limited by the fuel injectors.

There are a lot better things out there for the money (assuming brand new cost of a PFC F-CON, but I think you're looking at a used unit).&nbsp If you got an FD, the A'PEXi PowerFC is a very nice package.&nbsp For FC's, the A'PEXi S-AFC can tune fuel curves very nicely for a lot less money.&nbsp HKS does offer a cheaper fuel computer (forgot the name?) also.

Um I was told by MazdaTrix that the F-con could run larger injectors. I do have the Email saved. I told them my mods and they said the F-con would work but I may have to put in bigger injectors. There is 9 settings in the Fcon 0-9. The 0 would be the stock level every increment you turn it up the more fuel it adds. So if you are running rich turn it down. Use the GCC to fine tune it in more. So lets say you add bigger injectors and its at 0 and you are still running a tad rich, use the GCC to lean it out or enrichen it.
I would call or Email MazdaTrix on this. Do not just take advice from people on hear if you can deal with profesionals like the people at MazdaTrix. I have found there is good advice and bad advice on here. Some people on here just throw info out there and do not have a clue. You kind of have to develop a 6th sense somtime to weed out whats B/S and whats for real. Me I am gonna listen to MazdaTrix or Rotary Performance before some shade tree tuner. I myself am a shade tree tuner but I prefer to get my advice from a reputable source.

 

You really don't want me to go into what I think about Mazdatrix...
That basically explains your position very clearly.

I can't believe Mazdatrix told you that. WTF!!

 

Cant believe mazdatrix said what???

Everything that he stated that mazdatrix said is true. I know of many that use the hks fcon, and have no problems with it. With the correct knowledge of how to use the fcon and gcc, you will be suprised what hp numbers people are putting down.

Edit: I am aware that I am bringing up a dead thread

 

Let's see...

The GCC was never mentioned until later.
If it's not explicitly stated, the GCC is another add-on electrical component to the F-CON that is going to cost you several hundred dollars more to make everything work.
Yes, a F-CON + GCC will control larger fuel injectors properly, but the original posted made no mention of a GCC.
An A'PEXi SFC does the same thing for cheaper.
Hell, an HKS Super-AFR does the same thing for cheaper.
Bottom line, an F-CON + GCC costs signifcantly more unless you're getting one helluva deal than other options.

Hks unit new,... then yes, a LOT more expensive. The combo can be bought for under $400 used though.
