UpRev Cipher: anybody try theirs yet?

Seeing this is making me believe its probably more related to A/F sensor calibration.
Switch thoes puppies around and see what you get!

Dovla's sensors may also have the same cal tolerance... And since only two are being used you have a 1/4 chance of getting the same results as eachother (assuming there is a wide calibration tolerance in the sensors).
And I'm also not surprised at his high A/F ratio... Its very common when you stack mods. My Sedan runs as high as 15!
I need to hook up my EU.

To get the same results as Dovla, I say 1 in 4 because the 2 sensors can independantly read either nominal, above nominal or below nominal.
So if they are both nominal, the readings should essentially be the same. (nominal but I excluded nominal as an example)
Bank 1 can be high or bank 2 can be high. (these are two possibilities)
Both sensors can be high or low at the same time which will show biased but balanced results. (These are two other possibilities.)
Oh well. Symantics.

This is the fun of being engineers!
Now go switch your sensors around so we can get to the bottom of this. Switching the sensors around is easy if you have ramps. I would (and will) do it on both my Z and G, but I still need to get the Inovate Motorsports wideband electronics hooked up.
Although I didn't have the wideband hooked up, I have switch sensors previously on my G and it was pretty easy.

Went to dealer for WB swap, but this service isn’t doing any out-of-warranty jobs without service manager blessing and he wasn’t there today. Local Midas looked at it and said that this is too much work for them. If this dealer is going to charge me more than $50 it will probably wait until MRC receives their Dynojet sometimes this month.
