Why do you need to Sync your Ignition Timing?

Syncing the ignition timing when using an AEM Infinity EMS is a key step in the start up process.

Using a timing light to check the physical timing at the engine matches the timing value displayed in the Infinity-tuner software will ensure the timing #s in the map and in the data logs are 100% accurate.

This YouTube video will walk you through the step by step process of syncing/tuning the ignition timing.

Ignition Timing and Knock

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

For example:

  • Timing at the engine during idle is 20 BTDC (as seen by timing light)
  • 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.
