Knock sensor bypassed, why is knock retard still present?

Mine goes to 0* at 1/2 throttle or more.

Above 3000 rpm I have 0* timing pulled and just manually adjust with Boost Retard **** in car. Forget the KS or KM, you won't get anywhere

Just an FYI, I tried the resister mod again and for whatever reason, I no longer have the knock. This is the very same resister that didn't work last week...what gives? I've driven the car for a few miles and the guage hasn't moved from 0.0

(P.S. I got a 7 ohm difference between my engine and the frame ground with the engine running despite 3 good ground straps)

Correction, the Fiero can stay
. But it could still be on one line
I ran the ground to the same place I did before using the same wire and resister. Someone else, who has had their knock sensor and resister hooked up to a switch, mentioned that sometimes you have to drive it a bit before the knock goes away totally and other times it goes away right away.
Which wire coming from the computer is the KS wire?
Thanks
Brandon

It seems to me that perhaps a change in the source code or just a zeroing of the KS is in order. What would happen if GM had hired an employee that had forgotten to hook up the KS plug on say 4,000 cars? They would loose their butt in warranty repairs from blown motors. It seems to me that this 9* retard with the KS unplugged is somewhere in the source code or other calibrations on the PCM. I would go along with what Rich said and zero it with Tunercat or what ever your editor program of choice is. It seems like quite a fantastic fix if you are CERTAIN you are not picking up any knock.. flase or real.
