ScannerPro and a 91 Vette ECM with CCM not working

Post by -=Jeff=- »

I have tried to connect scanner pro and it does not seem to be working correctly. as it will not connect.

I have tried a couple different forms of macro commands to get it to connect with no luck.

Datamaster and Ease both work, Also I noticed if I send commands RAW with my homemade TTY program it will work, but if you send command too fast the ALDL line stops.

Another thing with my Homemade ALDL if I send a command the response echo of the command sent shows up on the second read.

Example, if I send
0xF1 0x56 0x08 (cksum) I need to send 2 read commands before I see an echo of the command sent.

Not sure what step to try next to get it to connect.. any thoughts?
