Mines an 06 with a different ECM, so good point about potentially different values on different LS4 revisions.
I will plug in a 10K radial and dial to suit. Post my results here when they are available.
884 or 8.8 K? We cant calculate the voltage drop without knowing the current flowing thru the resistor. 1K seems reasonable to spoof the ECM, however 10K would probably appear as an open to the ecm. If you leave it totally open does it toss a code? Is the resistor totally needed to prevent it from setting a code?
Just thinking out loud.
We shall see.
Interesting stuff. Thanks.
Cheers
Mike.

I think if you measure the resistance in the sensor, orange wire to yellow, it should be pretty close to the jumper resistance. Voltage divider says for 3.1v to go down to 2.1 with one resistor at 884 ohms, the other one must be around 450. If I recall correctly, I did measure that sensor resistance and it was somewhere around there.
I can say that for those of you that just want DoD off, jump the orange wire straight to the yellow, start it up a couple times till you get a light, remove jumper and reconnect sensor. DoD is now off.
