Scan Values???
I have an autoxray but don't know how to interpret the values, what is the block learn?? I have an 85. It always tells me it is "lean" even when I turn up the fuel pressure. I think it smells rich though. What should my o2 sensor be putting out?

BLM Block Learn Mode
This is your long term fuel correction. You won't see it change as you up the fuel pressuer. It takes time to adjust. A good BLM is right aroudn 128.
Look at your INT values. These are your short term fuel corrections.
As far as what O2 level you should have, you should only be concerened with the WOT values. This approach at best is still a hack. 450mV in closed loop. 850mV for good WOT.

Re: Scan Values??? (Gregory VanLare)
Thank you, that's a big help. I'm worried about my O2 values. They are all over the place, up around 844 and then down to 88 and up in the 400s. They don't seem to be too consistant and this is without too much variation in load or throttle. I replaced the O2 sensor last year. I thought they were an item that either worked or didn't!

As O2's age, their response gets slower. If they crack or get poisoned, they are pretty much flat line.
In closed loop, you wanna watch the cross counts number. Actual values of mV is only good for WOT info.
