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. If you need more help getting your Infinity ECU set up, custom Base Map or your current tune dialed in check out Infinity E-tune options and feel free to contact us any time. Don’t have an AEM EMS? No problem we tune just about everything, click here to check out our Tuning page for more details.
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.
Tuner tools for Ignition Timing Tuning
Here are a few of the basic tools/sensor and accessories we highly recommend for any modified/tuned engine. These parts & accessories can be found on all of the Brewed Motorsports built and tuned shop cars. From Drag to Drift to Rally we love all forms of motorsports!
- Knock Monitoring VE wide band knock sensor kit with Coax harness
- Wide band O2 sensor & controller, we recommend the AEM X series AFR gauge with 4.9lsu sensor
- Digital dash displays (fully programable color LCD race dashes) AEM CD5 digital display, AEM CD7 digital display or Motec C125 digital display
- 150 psi fuel pressure sensor or oil pressure sensor (0-5 volt output)
