like the title says is it possible to datalog a 2021 sierra 1500 duramax.. what software and cable is needed?
will datalogging leave any fingerprint in the ecm?

the 3.0 duramax is having an issue with intermittent start-no start.. many members believe its software related. what parameters should be looked at. example cam shaft position sensor
