10k resistor between a-b on aldl when hooking up scanner will send ECM into aldl mode which adds about 10 degrees spark and rpms goes to a 1000.

Take the "B" pin out of the ALDL connector under the dash. Seems like some cables put 10K across the A and B terminals and don't have a switch to disable it. Back the pin out and see what happens.

That makes sense. My usb to ALDL cable has a 10k jumper pin.
Google is your friend.
As a word of caution...read this in it's entirety and do not start throwing parts at it. Take the suggestions and perform troubleshooting checks to ensure the component is bad. This link is a good place to start and has some of those parameters that you been asking for. http://www.pirate4x4.com/forum/chevy...ing-speed.html
Thanks for Your help, and been there read that.
I also like to test the parts before changing them, but have spares for almost everything.
It would be easier if I knew what settings and range my AMUR bin expects to see from my sensors.
