Thought I'd share a screen shot of HP Tuners with the Wideband setup:
I boxed the AEM Wideband (super easy setup) and then boxed in the O2 mv settings.
Here are the readings just before I shut it off (after 5 minutes of running):
As you can see, the bank 1 and bank 2 (this is during startup - open loop) O2s pretty much stay in line in the first pic, but vary in the second. While crusing and when WOT, the mv for the O2's are pretty much near each other.
Edit: O2 mv avg is 503 mv. You’ll see it in the pic directly above.. ~450 mv is considered stoich if I recall correctly...
Not bad for wideband setup!
