I am just getting started tuning and am using an old MPVI pro and VCM suite version 2.24.686. My MPVI is currently on 116 firmware. I know I don't want to go past VCM suite version 4.0.x for fear of the firmware update to 121 which from the horror stories could brick the interface.
Being new to tuning I am trying to learn as much as I can from youtube tutorials. Some things that stand out so far in VCM scanner is my channel list/table display looks quite different, I can't seem to search for PIDs (and couldn't find the closed loop enabled PID), I can't tell what a "broadcast parameter" is, and the histogram layout looks a bit different. The only thing I have read regarding a benefit of VCM version 2.24.x is that you can potentially change the (hexadecimal?) file to change parameters that are not supported by HP tuners. I am not very techy and doubt that I would ever use that feature. Also I can't open files from HPTs repository as it states I need a newer version of VCM. I am just looking to tune a couple GM gen 3 manual trans cars using an AEM X series 30-0300 wideband.
With that being said, am I missing out on anything big or helpful in the 3.x or 4.0.x versions of VCM suite? I have read that there can be issues when reading/writing tunes using different versions of VCM suite, so if I should update I want to do it now and stick with it. I appreciate any recommendations!
