* Engine speed (RPM): Timing advances at higher RPMs.
* Engine load: Timing may retard under heavy load to prevent knocking.
* Engine temperature: Timing might be adjusted slightly based on engine temperature.
* Sensor inputs: Various sensors (like the oxygen sensor, MAP sensor, etc.) provide data to the engine control unit (ECU) to determine optimal timing.
Therefore, there's no static "degrees BTDC" value you can set. Trying to adjust the timing manually on this engine would likely damage it. Any timing adjustment should be done using a professional-grade scan tool capable of reading and modifying the ECU's parameters. Even then, it's generally not recommended unless you're experienced and know precisely what you're doing.
If you're experiencing issues with your Jeep's performance, it's best to consult a mechanic or use a diagnostic scan tool to identify the problem instead of attempting to adjust the ignition timing directly.
