Just found this article/advertorial on StreetLegalTV... Wideband Air/Fuel Ratios From Every Cylinder

Sounds familiar =P

cool stuff.

it is as if to try it once, get a generalization. put the stuff back in a box.
that is the sad part.

interesting to see the 8 needed to richen in the back..

Been there doing that, LOL

Geek is a Master at this! But is it fuel or air doing it? manifold problems, throttle body placement, then once on the track g force changes from the dyno.

We used DG's setup on mine at the engine dyno and it was a fascinating educational process. We touched on this in another thread and Scott was kind enough to post a screen shot from one of my pulls. If I can find it I'll copy it here. One interesting aspect was that it was impossible for me to follow eight digital readouts at the same time during a pull

Despite having two four barrel throttle bodies on a tunnel ram manifold the variances through the RPM range were a little unnerving. I have my headers set up so we can use the eight AFR set-up in the car and we'll try it on the chassis dyno next. Ideally we would run it in real world track testing as Its reasonable to expect some changes from a stationary test to an accelerating vehicle test. We learned a lot, but this capability will add significantly to the complexity of the tuning process.

BTW we mounted our sensors about eight inches down the primary tubes. This also adds some challenges with headers installed in the car.
