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 ..

    • I just got to work and skimmed through 61508 and 61511. I was surprised the CSA adopted both, but neither are enforced. To recap what I read, it states that in a perfect world, they should be segregated but they acknowledge that this is not industry standard and clearly mention that they allow mixing of safety and non-safety. 61511 also mentions software segregation like AB does in their safety PLC's.   Now if only I could go back to control, let alone safety over comms. In my current line of work, we're only allowed monitoring over comms. Everything critical must still be hard wired.
    • I've unfortunately never been as they're on the complete other side of the continent and another country that isn't currently letting us in as easily as they use to. I even heard their stop signs over there actually say "Stop" instead of "Arret". If I decided to trek the 48h drive, I wouldn't know when or where to stop haha. Whenever I order parts from UP Garage, I order from Japan as it's cheaper. Same with GKTech... oddly enough, it's cheaper shipped from Australia then it is the US.  UP Garage Japan operates their US leg though, unlike Tomei. If Tomei JPN had the power to close down Tomei USA, I'm sure it would be done in a day. They're two completely separate entities. Tomei JPN messed up somewhere originally agreeing to its creation and got sacked big time. 
    • I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap
    • I don't know that machine specifically, but I'd personally go for something with a little more kick than 130amp. Around up to 180 would be good. At the 6mm range, you're really pushing the machine hard and don't have a long period you can run for with out needing to give it a rest. Lots of MIG machines come with a regulator and hose. A lot will come with a starter roll of wire too, but it isn't too expensive to buy. I'd recommend NOT buying a massive roll too, as you don't want it sitting around FOREVER in the machine between uses and potentially going to shit. For thin sheet metal, get a roll of 0.6mm if you're doing over 3mm and above, switch over to 0.8mm wire. Even by 2mm you'd probably really want to switch. As for gas battle, it's all swap and go style now. You'll pay a bottle deposit, and then X amount to swap for a full one. I think it's like $200 or $300 for a D Size bottle upfront as "deposit", and like $110 to $150 per swap. My D size CO2/argon bottle lasts a fair bit of welding on the MIG. And I run an E size bottle on the TIG. For DIY MIG, stick with a D size bottle. If you really start to get into a LOT of welding and doing it really regularly, then upgrade. If you're like most DIY car guys, one D bottle will last you 2 or 3 years easily. I think I've been on my current bottle about 5 years. It is starting to get low, but I've been smashing it a lot more the last 6 months.
    • SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.
