How do you tune an ECU without knock control

[Bruce]

Always at risk about being hit by lightning.   Simple precautions tend to
min it happening.

Acoustic as implimented in the early systems (ie GM) is great, if you don't
do any tuning, and want to run too low of octane fuel.   Acoustic, in a
serious engine is marginal protection for the inexperienced tuner, IMO.
Thou, the J+S unit maybe the exception.

Course you just said some detonation is to be tolerated, so I have no idea
of what your standard is for *tolerable*.
