Tom got it working, Yey....... It was his cereal cable He got by for cheap, as he received one with something els he bought. Got to love free stuff. Im so happy, everyones adapters are working as planned

Sadly I'm without an adapter because the mail didn't show up today... Maybe on Monday...
I really wanna test this Jdash thing out!!! |

But SVXes were slow sellers in Britain and it's possible that this was a 92 model car that wasn't registered until 96. I reckon the '3' in position 5 might mean Europe whereas 'A' on the Legacy might mean UK specifically. What we really need is more data and it's an easy little side project to get people involved. I'd like to ask everybody who buys or builds a cable to post their ROM ID and the year and country of their car so we can see if there actually is a pattern to these numbers. It will also be interesting to see just how many different versions of the SVX ECU are out there.

software capabilities
Well, it seems you guys have gotten the hardware/cable nailed down to the point where it's pretty much going to work on every car. I'm wondering if we could get a complete list of what the software can, can't, and might be able to do. Basically, what can we do with this cool new hardware interface? Have all the registers or addresses been found for all the various sensor input values and driver outputs? Are we able to manipulate any of the data stored in the ECU?
I've been working with and doing a lot of research on DSMs and the associated DSMLink as well as B&G's Megasquirt lately and I'm wondering how close to that kind of programming functionality we can eventually get. I'd love to be able to have all that tuning and datalogging capability without having to replace the entire ECU. It looks like this project is heading in that direction or at least as close as possible with an SVX ECU. Thanks, Jay

Pretty much everything can be changed / accessed. First step is to decode the assembly language. From there, software mods are probably limited to available ROM or RAM space.

As of this moment, there are multiple software programs available to access the data on the ECU. Off of the top of my head: -VWRX SelectMonitor -Phil's ECUdump -JDash -RS232 Comm Tool VRWX's software can read and (when the INI is edited as per Phil's specifications) display gauges and data from all the sensors in the car. However, the software is very buggy; it crashes when switching between gauge and graph mode, and also has a strange issue which causes it to fall out of synch with the ECU. It's neat and all, but the bugs make it kind of annoying. Phil's software at the moment can only dump ROMs from the ECU and TCU (by modifying the source code). It actually has the code written to perform other functions, but a front-end for these functions hasn't been coded. If you're into C programming and Linux, I highly suggest you sign on to help out this project. Sadly I don't know enough C to help out much... JDash hasn't been tested by anyone, to my knowledge. As soon as I get my new adapter built I'll test it out. But it looks very promising. I know some Java, so it's the one I can probably help with. The program is at about the same level as VWRX's software right now, but I'm hoping it doesn't have some of the bugs his software does. The RS232 Comm Tool is a nuts-and-bolts program to be used only for testing purposes. It allows a user to send and receive hex data directly, without any interpretation. Meaning it will allow you to read and write to addresses in memory. However, you can only do one line at a time, so it's not useful for some of the big projects you guys are talking about. There are probably other software programs out there, but I'm not familiar with them, so I can't really help out. Right now, we don't have a "tuning" program. For that, I think Phil's program has the most promise. Like I said, it has the functions built in... it just doesn't have code written to use those functions. So there you have it. Hopefully this answered your question. |

We are really limited right now at a programming level. We need to get more people involved with programming knowledge, or at least more knowledge of the early Subaru ECUs. We have all the building blocks to come up with a powerful system to tune the SVX. There are a few other programs that we can use to edit the fuel, timing, timing correction, knock correction, and a few other maps. Then we can save the edited maps, and burn them to a ROM, and plug them into the ECU. The ECU will then run the edited maps. A few other programs not listed in Nomakes list are as follows. Note that most of the programs listed below are Java programs, and will run on cross platforms. Java is also an easier language to learn than C+ Enginuity- Phill and I have successfully used this program to edit the the maps on the ECU. I have successfully burt that map to a ROM, and had my SVX running it. TunerPro- I have used this program as well to successfully edit the ROM tables. I feel this is another potentially valuable program for SVX tuning and data logging. LogWorks 2- Although I haven't had much luck with this program, it could be of interest to someone with more programming knowledge than myself. There is a whole sea full of apps available for us to use, we just need a little focus, and some programming help. If anyone is a programmer, or knows a programmer willing to help. Please feel free to chime in

thanks all
Looks like we do indeed have several options. I have a friend who has some programming skills (he also owns a silver '92 wingless). I think he knows some C and maybe some Java but I'll check to find out for sure and maybe he can help with moving stuff further along. At this point I'll probably be looking at one of the programs for some logging. I've got this strange stumble.... but I digress.
Thanks again, Jay

Did you modify your own maps, or copy the JDM ones? How is it working for you?

No good... I got the USB cable today, wired it together, put it to the car and... nada. At one point I got nonsense data (random things like C00 when I sent "12"), but now I get nothing except when I turn the car off. When the car turns off, I get 00.
I've messed around with everything and I just can't get it working. I give up for now. Is there some piece I'm missing? All I need is the USB-TTL connector and the Metra connector right? |

Tobi got it working though... but it seems he left as soon as he sorted out his pin problem...
I left the guy a message on ICQ but no clue if he'll see it... So Phil. Check out the datasheet on this USB adapter. http://www.ftdichip.com/Documents/Da...DS_TTL232R.pdf There are a bunch of different options I can enable/disable in the chip's EEPROM, and multiple things I can do with the wires. Do you see anything that would prevent my setup from working? My setup: USB TXD into SSM RXD USB RXD into SSM TXD USB GND into SSM GND USB RTS# into NONE USB CTS# into NONE USB VCC+5V into NONE SSM VCC+12V into NONE EEPROM, Driver defaults Last edited by Nomake Wan; 10-30-2007 at 01:12 AM. |

Another thing... while the driver settings were posted earlier by Tobi, no one posted the EEPROM configuration options. So here they are:
In case they help. EDIT: After toying with the program I found that I was looking at a template and not my device's settings. I have re-linked to the correct screenshot of my device's settings. Last edited by Nomake Wan; 10-30-2007 at 02:38 AM. |

Hi,
Sry i read the message only now. Ok the wirring is correct. Do you use the VCP or the D2XX Direct drivers? Only the VCP-drivers works. Which OS you use? Do you have an additional COM-Port after installing the drivers? If the adapter works correctly, you can connect with the RS232-Comm-Tool without an error. I use the default adapter settings and it works. I only change the baudrate, parity, databits...... from my additional COM-Port but i think this is not the problem because the monitor-tools setting up the right values. |
