So many PIDs.....what do they mean?

Sweet!

The default '07 dashboard does make more sense now.

I do hate to be a nag but.........there is no A/F ratio or knock retard PIDs.

...........don't yell at me.............LOL

KNK ST RETARD - Knock Short Term Retard
DESIRED FA CYL1 - Desired Fuel to Air Ratio - Cylinder 1

If you aren't seeing those in your dash then I probably picked up the wrong file. You should be able to find them in the parameter tree at left if they are supported on your vehicle.

Ok, sometimes my elevator doesn't reach the top floor.

There is A/F and KR in the default '07 dashborard (I didn't scroll down far enough.....duh).

In the dashboard though it monitors KNK LT RETARD.

What is the difference between short term and long term knock retard and which one should I watch?

Also, isn't desired fuel to air ratio the target ratio and wouldn't open loop air/fuel be the one to monitor?

I can almost promise those are my last questions!

BTW - I really do appreciate all the help, both here and in the LX forum.

Thanks again!

You should use the knock short term retard. You can either modify the dashboard yourself and save it, or download version 3.1.5.0 which has the correct file. As for the a/f that is a question for Johan.
