Colby - I have reason to believe that 1.29a doesn't support OpenPort 1.1.
On a virgin laptop that has never had any OpenECU software...
Installed ECUflash129a.exe (updated/fixed the driver install bug)
ECUflash doesn't respond. "No Vehicle Interface" detected. The program intsalled fine and it even ran the openport driver setup. ECUexplorer is able to log data at this point.
Uninstalled 1.29a and installed ECUflash 1.27. This time I noticed the driver installation is different. It looks like it installs a different set of drivers as compared to 1.29a. So now my OpenPort 1.1 cable works fine with 1.27
Any thoughts?
