ST3 TPS setting?

Please excuse me if this has been posted. I haven't found it yet after reading dozens of posts about setting up these bikes.

So we set the TPS to 150mv after making sure the throttle plate is closed. Easy. Now we set the throttle angle to some value. The DesmoTimes book says 3 degrees. The Ducati manual says 2.3 degrees. This should be the base idle. The bleeds are used to fine tune the idle.

Is the Ducati method simply producing a very lean idle, whereas DesmoTimes produces a rich one? Mine is set at 3 and sounds & smells rich at idle.

thanks in advance

It may be different on yours but on mine I adjusted to the idle mV setting with the idle screw after setting the baseline at 150. That controls the fuel, not timing. Are you sure you're reading it right?

Have you ever reset the TPS? If done the way you did it, I do see the need for a reset, but once reset, life could be tricky to make sure the ECU understands that 150mv is actually zero on the throttle plate (and not a posible negative value)
Yes, I've done it a few times. I don't know what you mean and wonder if you are over complicating the issue? How do you get a negative value?

With the throttle plates closed you set the TPS at 150 mV and snug her down. Then you adjust the idle screw to 460 (I think for my ST4) or whatever, that's how mine works but your ST3 could be different, hopefully someone here has one that's done it.
