ALDL Connection Failure
Hi, I'm trying to datalog my 93 M6 for the first time and cannot seem to get the car to connect to the datamaster software. I have the Moates cables. When I run the ALDL test program from TTS's website it fails the test. I did also install the driver software from TTS's website. The ALDL test program picks up the cable in the com 3 port but then fails. I tried to use datamaster to see if it might work anyways but it would not even recognize anything being in any of the com ports. I have the Moates box set to the "open" setting as is instructed on Moates website. Any ideas why it is not working?

Are you using Windows 7 or older? Have you downloaded this driver?

Are you sure you're using a USB 2.0 port, because not all are 2.0.

I was using windows 7 and downloaded the driver from the very bottom of the downloads page here. Yes I made sure to use a USB 2.0 port. When it didn't work I also tried a USB 3.0 port but then even the tester didn't recognize it being plugged into the laptop.

Sorry I forgot about this thread. The solution to the problem was I had to click the "disable ccm handshake" button. Sorry I forgot to update the thread. After doing this the cable and program worked perfectly.

I help a lot of people with tuning issues. Can you explain how this disabling is done please?

I cant pull it up without using up one of the last free trials I have left but there is a setting under one of the menus for "disable ccm handshake" and "disable digital data refresh" I checked both of those boxes and the car was able to communicate with the software.

Found where it is here: https://www.corvetteforum.com/forums...-1993-lt1.html
Its when you enter record mode under the options menu at the top. It seems to be a very common problem with 93's from my reading around.
