Pictured above are spark plugs. Spark plugs receive electricity on the order of 40,000 to 100,000 volts from the ignition coil and distributor. You can specify when they fire.


What you do:

Set your timing to maximize power.


For Hipermath, ignition timing is set according to the time it takes to ignite and burn fuel so that the flame/pressure front contacts the piston at top dead center. Ignition timing is measured in crank degrees. The rpm you use for this equation should be the same rpm you chose for "ignition timing rpm".

The HiPerMath equation is:

ignition timing =       (2.895)(360)(stroke)(ignition timing rpm)           + 3       You choose the "ignition timing rpm" in your engine specifications.
                                        (compression)(60)(1000)

which reduces to:

ignition timing =       (0.01737)(stroke)(ignition timing rpm)           + 3       You choose the "ignition timing rpm" in your engine specifications.
                                              compression

The + 3 at the end is to compensate for combustion chamber height.
