Problem With Evo 9 Ref/Sync

[Loqy]

Hi,

I've problem with ref/sync for Evo 9 M800 Pnp
Sometimes Sync voltage was 5,907 volt, sometimes 7,330 volt that's why the engine idle sounds strange.
After around 30 minutes, engine went off, then I have 2 captured while cranking.
I tested pin voltage from ecu pin 50 is 3.7 V ; pin 43 is 3.7 V ; pin 53 is 4.8 v All tested without sensor connected.

All the sensors are brand new & wiring is OK.

Please advice if there is something wrong with the MoTeC ecu or others.
