Ignition Timing and Knock

Syncing the ignition timing is the 1st step in tuning the igntion timing of any engine to ensure reliabilaty and peak torque output AKA Horse Power. If the ignition timing is not sync’d correctly AEM tuner and AEM data will not display actual ignition timing.

For example:

Timing at the engine during idle is 20 BTDC (as seen by timing light) a
Timing in AEMtuner displays 15* ign timing during idle
20 – 15 = 5, this means the entire timing map will be off by +5*. This can easily lead to knock and engine damage.
