These are additional PIDs not in the list included with the app.

VPW/J1850 vehicles Edit

Used in all OBD-II equipped GM models from 1994 through 2003 and was gradually phased out in favor of GMLAN from 2004 to 2007.

Some official literature (definitely doesn't include most codes): https://service.gm.com/gmspo/mode6/pdf/GM%20Class2%20mode%20$06%20data%20final_dm.pdf

The below were discovered by GaryDoug on firebirdforums; originally claimed to only be for F-Body vehicles but should work on all VPW-equipped cars with the corresponding features equipped.

"Bit" unit values are booleans; 0 for off, 1 for on.

Querying engine-specific PIDs on the wrong engine is safe but will give invalid/dummy values.
