Re: Advancing ignition timing: what is it?

Basically, advancing the timing means the spark plug will fire sooner giviving more time for the air/fuel mixture to burn and creating more cylinder pressure. This normally results in more power but can also lead to pinging if too much timing advance is used or poor quality fuel is run.

EF's run a coil pack ignition system with a crank trigger so you cannot adjust the timing like you can with a distributor setup. The EF computer automatically advances timing, to a degree, until the knock sensor detects pinging.

Would it be worth it/safe to advance the timing in my Dedicated LPG EA

No.
You'll get some benefit at idle and low revs but you'll end up with way too much advance at cruise and top end revs.

LPG requires more advance at low revs but less at high revs
