That's all you need to know but just incase you want to know more The TECH & BENVO are always eager to explain more in Depth

If you set targets that are too high, and you are outside of the DME's programmed adaptable range of retard, then the car will run that timing even though it's knocking. Is a knocking engine safe? No.

There are also 'minimum timing' maps which signify the minimum timing that can be run.

But thanks for chiming in.

The ignition targets set by the factory are quite radical to start with for a production car and this is really down to the excellent knock detection system.

The type of fuel is not just restricted to ignition timing....
Absolutely correct.
