HI can you please confirm that a minus (-) figure indicates that the timing is retarded and a positive (+) figure indicates the timing is advanced.

Many Thanks

Richard

On a random module, in some car? No. Can't confirm the meaning of much of anything. ;)

That's still not enough to identify the module exactly.

But yes, on gasoline engines, the general rule is that - means advanced and + means retarded.

Well, an actual Auto-Scan would be nice; that way we could see what we know about the exact ECU in question.

Another thing you could look at is what that data shows when the engine is running. Petrol engines, once they're running, basically never have ignition timing retarded (after top dead center).
