I know their website says to take the the sensor out to calibrate the sensor but in my case I have no cat or muffler and it dumps out the side so I really wonder how much gas stays stagnant in the exhaust. If the car hasn't been run for 24 hours would it be ok to calibrate the sensor while it's in the exhaust?

I would still take it out, you want the calibration to be exact! Thinking it's starting to stray? I've been wondering the same thing about mine, the only way to check is to recalibrate it, it's been about a year since I did it last.

take it out yo. calibration is an exacting science!

Not only, but the heater mechanism is sensitive to voltage, so it's better to have your car running when you calibrate your sensor.

ooo, good point. if you do have it running, make sure the sensor is far enoguh from the sensor bung so it doesn't smell any exhaust. if i remember correctly, i had to bring my 13.8v power supply out to power it, as the battery didnt have enough juice with the car off

I could hook my large Craftsman battery charger/starter to the battery during calibration. I've never measured what the output is on the 12v high or start settings is but i'm sure it's enough.

Last time I calibrated the sensor I left it in the exhaust, but I figured it was ok since the car hadn't been run in a week.

If you're using Megasquirt, you can also go into flood clear for about 15 seconds of cranking, but it's still a better idea if you just remove the sensor, plug the bung, and pull the car out of the garage while you're running it to calibrate the sensor.

So I've never even heard of calibrating the O2 sensor. Is that bad?

It's bad if you're serious.

Dammit. :rant: Yes I'm serious. Is this what I'm supposed to be doing? http://wbo2.com/sw/conf.htm

And would this http://wbo2.com/sw/conf-afr.htm be why my LD01 doesn't agree to MS/MT?

Any more help? :yikes: I hate surprises like this.

You have to use the config software it the link to calibrate. Download the newest version with free air auto cal because it makes thing so much easier. I believe the instructions are all on that site, but...
Remove the sensor and place it somewhere out of the way of the exhaust
Power up the wb02 controller and let it sit for 2 min so it can heat up and stabilize
Run the auto cal feature in the config software and click *update* when done.
I believe that's all?
