After reading of a few users having success with this, I purchased the Dashcommand obd2 app and bought the additional PID for my 1999 Tahoe 5.7.
When I go to the pid page and add CMP offset for my truck it just will not work or display any data.
Does anybody know the steps to do this correctly? Thanks.
