Hi all,

I've recently acquired an old 2011 Zero DS which was sold to me with the promise of having intermittent throttle cutouts.
I can confirm.

I'm hoping someone has one lying around in 'factory' condition and can help me confirm some of the behavior I'm seeing.

I've tied together one of those ODBII debug cables to check if the MBB has anything to say for itself:

Today, after startup, it responded to throttle a few times, and now it has cut out.
There are no errors in the MBB, the log doesn't say anything of consequence.

If I check the inputs page, the kill switch is in run and the stand is up.

If I open the throttle, the out value according to the MBB is 3100 mV.

If the MBB outputs a voltage signal, I would expect the AXE controller to be in a 0-5V mode instead of a 0-5k potentiometer mode.

My AXE controller starts up with one green blink (which should mean 0-5k) and then a solid green for run.

Can anyone confirm that the AXE should start up with a single green blink?

And: Can someone show me a comparable MBB log?
