2022 Update.
Did anyone having the same issue?
My Torque Pro was working with files mentioned in the 1st post, but with another adapter than OBDLink MX+. But recently, most likely after some update in 2022 of Torque App as I'd assume, it lost the PIDs and Layout. I didn't use it for a while, not sure how long was it this way, but when I tried last week to remap everything according to original poster, Torque Pro App doesn't see nor recognize the PID file, it doesn't show up in the directory. So basically App default to its original stage and not allowing to use old methodology to insert custom PIDs.
Wondering if anyone else experience same issues and have a way around to get PIDs back...?
