Discussion and questions related to the course Road Tuning
For the base ignition map, what fuel grade is recommended. Here in the US what we can get at the pump varies from 91-93 octane. Would the base ignition map sample be safe with 93 octane?
I'm sure it would. It does depend on the compression ratio of the engine. If you had a 15:1 you could probably start with even less timing.
