Anyone know if, once a car's been mapped, even if you don't add any more mods is it worth getting it mapped again periodically? Just to make sure evrything's running perfectly and as it should be? Just a thought
The maps do not change. Though if you have some knock, the ECU will remeber the octain number and make small adjustments. But the ideal is not to have to rely on this, just get dam close to it!
If you are running a close to the edge tune, there are so many logging/AFR tools out there, you have no excuse not to know whats going on with your car. Most others don't need to bother with another tuning sesion unless you change something or have a problem.
