subthrottle wiring diagrams anyone?
Does anyone have the service manual and would want to scan the wiring diagram and service section for the subthrottle controls? Someone with some fairly basic circuit and programming skills could probably whip up a controller for about $100. Something that gradually opens the plates to prevent driveability problems and doesn't keep them closed below 5K. I wouldn't mind giving it a shot.

So far looking at other kawasakis (ZX-6R) ecu pinouts, there looks to be 4 subthrottle output signals. This most likely means it's a stepper motor. Not new news. People have posted this before.
There also is a subthrottle sensor O/P signal that looks like a second TPS signal for the subthrottle.
I also read (somewhere) that the bike cycles the subthrottle from fully open to closed and memorizes the TPS voltage.
It would be ideal to datalog the two TPS sensor signals and associated rpms to see how the subthrottles are controlled. Simply closed before 5k and open after? Or more complicated opening and closing that sort of parallels the main throttle plates.
