I am looking to learn more about the OBD 1 ECM's to datalog and scan using the USB OBD 1 adapter I have recently bought, particularly I have a '91 Silverado and a '89 Camaro. Just begining to get into using my laptop to datalog and scan as the TECH 1 at the dealership where I work is broken and there is no talk of replacing or fixing. Still searching for that software to use for datalogging and scanning. Followed a link to this gearhead's forum by checking out TunerPro RT for my possible software. So thought I would join to learn more about this software, talk about my projects, get and possibly give advice if asked!
