Waste Gate Duty Cycle

Can the waste gate duty cycle go to 0%. I have a SY137A chip and I am only used to seeing it go to about 69%. On a run I made today it went from 100% to 0% and back to 100% without any numerical change in between.
On the last engine take out, the WG bracket did get bent but I managed to bend it back in place. Could it just be bad data?

Here is the location of the DM file:

It should be called Wastegate or 053005test.

Thanks,

Clayton

Re: Waste Gate Duty Cycle

Correct me if I'm wrong, but I think at 0, the wastegate is fully open and at 100 it is closed.

Re: Waste Gate Duty Cycle

Found some notes I printed out from BG on data master values and he agrees that the parameter is 0 to 100. 100 being fully closed. I just never had it open all the way before, but I don't have a lot of DM runs racked up yet. It was also weird that there was just a step change from 100 to 0. Could be how I have DM set up I guess.

Thanks.
