See the notes on advanced scanner options here: https://www.hptuners.com/help/VCM-Sc...-overview.html
Just want to start some dialogue to see if anyone has used this feature with success. The descriptions of fallback and override make it seem like there is some additional setup required for the properties of each. I tried to use this on a supported vehicle that doesn't report, or misreports its Operating System ID or VIN with no luck. Previously, when I asked support about scanner issues they noted this vehicle would need the VIN written into the PCM with OEM tools. I took this to mean the scanner cannot decode the VIN (since it is not there) and it does not know what vehicle it is connected to. I have not had the PCM flashed yet but this feature seems like it was made to overcome the lack of VIN situation so we could at-least data log. Or maybe this is for a different purpose?
