Shane,
The forward O2 sensor(s) is replaced with the one supplied in the kit.
They (HyperSpeed) claim it's a high-speed Lamda O2 sensor (those are
expensive). The proto-type kit retails at $399 with the final released
(programmable) version being some where in the $500 range.
It does affect closed loop some what in the sense that it looks at the
O2 sensor and it "adjusts/corrects" the mixture via the controller.
I'll try to run a test to see what the differences are with the factory
O2 and then with the HyperSpeed connected. All I can say at this time
is that it's much more responsive with the new controller than without.
I spoke with a gentleman who has this controller on his stroked
Viper...he made 30RWTQ and 20RWHP more with the controller...on top of
his current modifications.

Good analysis - thats what I was thinking. I'm still perplexed by the
narrow-band issue. Wondering if the replacement sensor might be a
hybrid or "less-narrow" band sensor. If so, and the price is less than
$500 - it would be a bargain.
Keep the ideas coming - Latr,
