I tried to validate PIDS today on my friends 2015 Camaro SS (E38 ECM). After connecting to the car with V7 build 303 (using V2 in pass-thru) I validated PIDs and everything seemed to work correctly, but after disconnecting and closing V7, there were no .vml or .vpl files starting with his VIN in the EFILive/V7.5/PIDs folder......
Thanks
