Hi I was wandering if somebody could please help me out understand how is the igniting timing affected when the vehicle is running in limp in mode
this is for studying purposes
i know limp in mode will run out of a pre-programed chip information and that it will run rich but how does that affect timing?

Do you
have the same problem?

Stays in base timing instead of advancing according to power needs.
