Fortunately you will never be mapping my engine.
Proper mapping implies getting to the lowest timing level that achieves optimum power/torque for any given load site. It most certainly does not mean trying to achieve as close to detonation as possible.
In some or many cases that may not be achievable and detonation may prevent further timing. But that still doesnt mean you run right at the borderline with detonation at all times.

Although I would agree with this statement. But I certainly dont need a soundproofed cell to be able to hear. Good quality ear defenders eliminate pretty much all exterior noise anyway...so wherever I am using them, I have my own private soundproof room....even if it's sitting in a car.
