Problem diagnosis with Predator - is there a guide?

[hmwave]

I was wondering if anyone ever published a "How to diagnose problems using the Predator" or "Making best use of the Predator" guide.

Something that would explain all the PIDs, what they really mean, what the values should be for a healthy motor, and what to look for to uncover developing or existing problems.

If not, do we have any resident Predator or OBDII experts here?

I searched Diablo's site but couldn't find anything of value (kinda pisses me off that despite spending a bunch of money on the Predator it's true value hasn't been fully realized as Diablo's documentation is weak).

Reason I ask is my motor has developed a bad misfire around 1500rpm and the motor is also running rough. No codes have been thrown.

I'm surprised it has not thrown a code... could be a number of different things. :??: If you have had it tuned you may want to take it in to them and have them take a look at it.

So no experts then? ;-)
