Knock Tuning Tips
y Set both Retard Limit and Retard Limit Long Term to 0 degrees.
y Listen for detonation while running the engine.
y Introduce light detonation very carefully and log the knock
percentages.
y Estimate the Ignition Retard required preventing this level of knock
continuing.
y Adjust the Instantaneous Term trim parameters:
Start with values which will cause too much retard.
Work your way back until an appropriate strategy for the type of
engine is found.
y To start, work with Instantaneous Term trim only
y Add the Long Term trim parameters later if required.
