Bros, Windows 7 USB adapter (DIY/FTDI) fail
 

I've been jacking with this thing for a few hours now and I can't win. My old computer can communicate just fine as of right now on XPs3 but this new Windows 7 machine will not connect:

I know I have the comm port numbers right, I've installed the software from DIY's site and from FTDI's site and I still can't get a connection. I'm not really sure what to do next but I've installed both sets of drivers, rebooted, and I keep getting this problem.

I need to tune a car tomorrow and my old notebook's screen broke off so I don't really want to use that computer. I suppose I could duct tape everything together, lol.

Thanks for the help gays.

I went through the trials of getting this to work with my Windows 7 netbook. Here are the steps I took to get mine working. First I ended up using a GigaWire Serial to USB from radio shack, I really hated spending $50 bucks on one but it was the only one that was consistent and had half way decent drivers.

Second, right click on comm port 3 in device manager and hit properties. You need to get rid of the "delay" that windows has on this by default and set the baud. So once you right click, go to the port settings tab, set the bits per second to what you need(9200 for MS1 and 115200 for MS2), data bits 8, parity, non, stop bits 1 and flow control none. Then click the advanced button; from here make sure the box at the top "Use FIFO buffers..." is checked and drag the buffers all the way down to 1.

At the bottom you should also be able to verify the comm port you have assigned. After you exit device manager, open TunerStudio and your connection should be stable!

Thanks, baller.

I screwed up. When I set up MegaTune I always started with the "communications" adjustment. I should have:

1. set the comm-port without the confirmed test
2. opened a new project and set-up the "ECU Definition" before setting up the comm-port information
3. then gone back and confirmed the comm port
4. then started charging people for tuning

I guess I learned something really simple today.

i was going to say, the DIY usb adapter totally works with win7.
