PowerFC software

[calvintys]

Hope will give you guys some idea

The inside of my box looks exactly like that, but totally different.

[calvintys]

ohhh there are 3 different type of BOX.

[Skylineusa]

Oh, that explains that. Cool, thanks.

My Circuit board has FC-BOX-01-00 © SR 2001 on it

OK... too lazy to upload pic now

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????

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

http://www.skylinesaustralia.com/forums/at...achmentid=22277

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.

[funkymonkey]

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?

ok i understand but why do u need to hack the power fc to get the software to work with it? cant u just plug the power fc into a laptop and tune that way?

Dave

[funkymonkey]

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

[David Kemps]

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.

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.

[Ustasa]

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.

If you guys are going to all that trouble...wouldn't it be easier to replace the chip in the factory ECU and write a program to frig with that?

[David Kemps]

if u go view - font- change to NSimSun font and 20 size its not squished up anymore and much clearer.

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 ..

[R33vit]

Will the Datalogit interface box work with the Power Excel software??

I have schematics for it

Might help things move along.
