Figured that we should start a new thread for flashing so we don't confuse people who are just trying to log. This thread will discuss anything related to flashing with OS software. We can also include the use of the RR map editor in this thread too.
Here is the quick rundown of the steps needed to read or flash the ECU using an Autpnostics or VAG-COM cable other than the Tactrix cable. I will get screenshots eventually and post them here too. A couple steps are just little things to make sure it's hassle free. Some people may flip a couple steps around, but this is my basic ritual when using ECU flash.
Warning!!NEVER try to Read or Flash the ECU if ANY other program/driver has locked up since the last reboot! This can cause the PC to lock up in the middle of an image and that's not good so please only do this if you understand the risk involved and are willing to accept it. Again, failure to follow these procedures to the letter may result in a "bricked" or unusable ECU. You are doing this at your own risk.
Here we go:
1. Get in the car.
2. Connect the GREEN "TEST" connectors that can be found just a hair to the drivers side of dead center behind the glovebox. They are tucked away in a little compartment behind the top of the carpet. Find them and connect them.
3. Reboot the computer and/or let it completely boot up.(Just to make sure the drivers are all clean)
4. Connect the OBDII end of the cable into the car's OBDII port if it isn't already. The OBDII port can be found below the dash on the driver's side off to the left of center.
5. Connect the USB end into the computer and wait a few seconds. It takes the computer a few seconds to find, recognize and load the driver for the cable.
6. Turn the key to the "ON" position. At this point the dash should light up like a Christmas tree, the fan should start cycling on and off.
7. Start ECUflash, You should be able to select Read from the file menu.
8. A window will pop up. This looks like a logging window, but it actually wants you to select your ECU/Vehicle, so select your vehicle class from the list.
9. Click the button at the bottom of the pop-up windowand it should start reading and logging progress. Your odometer should read "ErHC" after you connect to the ECU.
10. Once the image is read or burned, you can exit ECU flash and turn the key to the "OFF" position.
11. DISCONNECT THE GREEN TEST CONNECTORS!!
12. Turn the key forward and wait until the seatbelt dinger stops and then start the car. Any time the ECU is reset or re-flashed; it needs to re-boot. This is done when the key is first turned to the "ON" position and takes about ten seconds. If you don't wait for the re-boot; you will just be cranking and wearing down your battery until the ECU is ready to go, so just be patient and wait for it.
If you still need to install the drivers for your cable or get it configured correctly please read below.
This is taken from my other thread "Using the Autonostics Cable to Datalog": http://www.legacygt.com/forums/showt...t=96737&page=6
Here is what you need to get started:
First off you will need a driver for the cable that is not included with it. This is the winXP driver we use: FTDI 2.04.06
Others are available here : http://www.ftdichip.com/Drivers/D2XX.htm
Extract the .zip file and remember where you put it
as you will need it when you plug the cable into the usb port and the install box pops up. During the driver install; point Windows Installer to the folder where you placed the unzipped files and install the driver.
You may need to adjust the cable's/driver's COM port settings in order to get it to work properly:
1. Go into Device Manager for Windows(right click "my computer" on desktop, go to Properties, then Hardware tab and click "Device Manager" button)
2. Look under ports(COM and LPT) for the FTDI port(cable must be plugged into the computer at this point) and right click and go into properties for the FTDI cable driver.
3. Go to the Port Settings Tab click the ADVANCED button and look at the BAUD Rate. If it is 9600; you will need to drop the box and change it to 4800.
4. This should slow the data rate of the driver/port and allow the cable to connect to the car's ECU properly. Be sure to note the COM port number assigned to the FTDI port as you will need to select it in the logging software.
The ECUflash I used to read my ECU image/ROM is available here: http://www.openecu.org/index.php?title=EcuFlash
THIS CABLE WILL
WORK WITH CAN-BUS ECU's.
However, if you have done ANY research into the subject; you would already know that. That is the reason they created the Tactrix v2 cable...
