I'm a bit confused, you guys are talking about the FC Datalogit made here in New Zealand, but what is that software I downloaded? It's from japan obviously, is it for tuning the power fc ie, the actual legandary software for Power FC that everyone always talks about but only the japanese have????

Dave

there's two types of cable adapters you can use. a standard one, and a extended one, which allows you to hook up a wideband O2 sensor etc.

I've made up an extended adapter and have a PCB made up n all for it. However to use the homebrand adapter on your PFC you need to replace the NEC I/O controller chip in the PFC with a blank one which has a cracked firmware on it. This is where I'm stuck because I can't for the life of me get my hands on the NEC programmer (I can get the blanks but not the programmer). This is deomnstrated in this pic... http://www.skylinesaustralia.com/forums/at...achmentid=22279

this is the standard version of the interface

this is the extended version

which has extra input ports.

The rest that you've pictured are prototypes. Hope that helps you guys a lil.

we're talking about the Power FC Communication software that is used by Power Excel tuners to tune PFCs. Not the Datalogit. The PFC communication software's been on the market (if you knew where to look n who to ask) for about a year now.

basically if you wanna tune your own power fc this is what you do...

a) get power fc

B) open it up

c) desolder the NEC I/O chip from the main board

d) get a blank version of that chip

e) get an NEC programmer for that chip

f) put a cracked firmware on the chip

g) solder the chip back on, or better yet, get a quick snap socket for the chip

h) plug the ECU back in and pray that it works and you haven't flushed $1000 of PFC goodness

i) make yourself the home-brand adapter (standard or extended)

j) install the communication software that corresponds to your PFC

k) do a serial connection and tweak away

simple enough? :D

because the power FC isn't meant to work with homemade circuit boards. it has a CRC checksum I think that it applies to the I/O to see if the data is being sent thru a proper Apexi supplied data cable. Which makes sense. But that's what I think anyways :D

Is it not easier to reverse engineer the datalogit so you can solve that problem without opening up the power fc and have datalogging capabilities?

I'm not electronics engineer, but if datalogit can do it, surely we can too by looking at someone's datalogit.

Dave

I am quite certain you do not need to de-solder anything in order to use that software to tune the Power FC

When that Jimmy guy tuned my car with the same software, I do not remember him removing any chips at all. He just plugged the box into his laptop and to the Power FC.

Jimmy is an authorised excel dealer in Taiwan and hence has the correct Power FC cable/box.

What funkymonkey is saying is that if you don’t have the legit cable/box then you have to figure out a way of inputting/outputting data past the protection chip inside the Power FC.

i'm sure it can be hacked.. even if you have to hack the software itself.. they cant have spent that much on the protection... and even so its only circa early 2000's protection which was always cracked.

If Maya and 3d studio and the rest retailing for $10k or so .. have been dongle hacked, so can PFC ..

now do we have any russian crackers in the house?? hmm ..

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
