Got mine working. Did a couple of things. Re-did the installation as per qikslvr's instructions (which I'm pretty sure I had it installed correctly anyway), uninstalled RomRaider 0.5.1, and installed RomRaider 0.5.0 (went backwards one version). And this time, I installed by "right clicking the install file and running as administrator", since I have Vista.
Not sure which one of these helped, I'm pretty sure it was the version of RomRaider. I bet the 0.5.1 would work, but I may have botched the installation somehow. It never stated "Trying to connect to ECU" when I opened the logger. It would just always say "Stopped". Either way. Another success story. Got this one from eBay and not Autonostics. $20 datalogging cable? Thank you very much.
