Mine too. My diesel's been idling rough.

I've told you countless times that its time to do the LSx coil conversion.

Related question... If I have an OBDII reader, do I still need a timing light to advance timing?

Thanks!

Does your OBDII reader record the timing setting? If so, you don't need one. If it doesn't, you do. What year is your car?

You can set the timing with an OBDII scanner?? Link please.

You can't set timing with OBD2 scanner... It only shows what the ECU *THINKS* it is running at.

I have to check. Haven't hooked it up yet but I'm guessing so. If the ECU supports it this reader should read it. It's a '97.

Exactly. I was just hoping to use it as a readout while adjusting the timing. But you're making me think that method isn't very reliable...

It won't change with you manually adjusting it. It still thinks it is doing the same thing.

When you "adjust" the timing you are changing what the ecu sees as TDC of the motor. It is an unseen adjustment to the ECU.

Perfect. Well, not "perfect," but this is exactly what I needed to know. Thanks!

I suppose I could still use it and simply advance timing until I get knocking. Does the ECU report knock count? Probably not the best idea though...

The knock you would be looking for is around peak torque with peak load... not something you do while setting the timing.
