Schrade, Looks like continuous linkup failures. Also looks like you were trying to view data in monitor mode. That's ok but no recorded data available in monitor mode. Lets do a bit of review.
1. You are using DM32xZ1 for 90-92 Y car correct?
2. Options-advanced-usb interface in use must be selected on the serial data acquisition form
3. USB driver latency setting is set to 1 ms.
4. Some corvettes including our ZR-1's LT5's have difficulty linking up. (as you know already) To get past this issue the ALDL link timing must be adjusted.
Bring up the serial data acquisition form and from menu select options/advanced/serial com timing. This brings up serial com timing form and allows you to adjust ALDL link timing. By default it is set to 0 delay in ms. TTS shows the optimum values to be between 190 and 205. To establish optimum setting it is necessary to find lowest and highest delay setting that works and then set in between. Start about 195 and work your way up or down to find the limits. Each time you make a change press ok button. then retry the connection by pressing start or single button. Repeat until upper and lower limits are found then set to mid value. Usually this is very narrow range of about 4-5. I had to do this to get my com port to link and stay linked.
5. If the CCM is not working correctly or the car is modified it may be necessary to disable ALDL handshake and/or options- advanced- disable dash refresh in order to link.
Hope this helps. A great help to you would be the TTS ops manual which you would have to download and print.
