Removing Engine Spark Knock or Pinging
via Timing Vs Engine Temp Map
v. 08242012
There are many aftermarket engine configurations, fuel quality and payload variations associated with proper
ignition timing. For this reason, it is impossible for the ThunderMax Base Map library to be a perfect match for
every engine combination. However, the ThunderMax library of base maps will cover most popular engine
combinations.
For those engines which require custom settings, adjusting the ThunderMax timing maps is a simple and
effective process. This will allow tuners and users to set the ignition timing for their individual engine
requirements, and remove any pinging present while operating the engine.
Note: All ThunderMax base maps have been developed for use with premium octane fuel. Use of boutique fuel
additives, stabilizers or special rare earth spark plugs, which could affect the combustion flash point, is not
recommended.
ThunderMax Ignition Timing Myths
Myth # 1
ThunderMax does not make automatic adjustments or timing corrections.
False - ThunderMax automatically adjusts timing tables for the following changing conditions:
Changes in Engine Temperature, Barometer, Intake Air Temperature plus a Separate Scale for
Boost Applications.
Myth #2
ThunderMax does not allow access to adjust small moderate or large changes in specific areas of
timing related to RPM or specific Throttle Positions.
False - Easy access exists for making changes in timing relative to any RPM and Throttle
Position. Additional changes can be made by Engine Temperature, Engine Speed, and a
separate Rear Cylinder Adjustment are available.
