DPR current/O2 sensor voltage



Okay, I've looked in the Bentley, and can't find it, and figured someone
could give me a quick answer.

I'm wanting to adjust my mix on the 16V, and finally got a harness hooked
up to measure DPR current, right now it's fluctuating between .1 and .2 mA
and I seem to remember the goal being just rich of .5 if I could remember
whether higher is richer or leaner. I know it's "righty richy" on the
Allen key.

So question one is does low = rich or lean, and what's the target value?

Anyway, I'll check the O2 input first, it should be 5ish too, on whatever
voltage scale, right? (0 being dead and 10 being full rich?) I have it
written somewhere, but it's been two years since I last checked it. Sorry
to be so non-technical here, but the car feels like it wieghs 4000 lbs at
the moment, I'd like to reduce the dog factor. It's gotta be near where it
can't adjust out of it.

That makes question two "what is ideal value for the O2 signal?"


Thanks.
