Got an event today with the new SW:
20241028_0753_rev85_brakedown.emublog3 (1.8 MB)
The new channel “DBW M32 DBW Off” jumps from 1 to 2 at the event.
What does this mean?

The new channel “DBW M32 DBW Off” jumps from 1 to 2 at the event.
What does this mean?
M32 DBW OFF means that the 2nd microcontroller get a command to disable DBW control (mode of H-Bridge operation).
Based on additional data the main microcontroller didn’t send such command.
I need to think and analyze code, but probably I will add more debug for the next build as we are very near to isolate the condition that cause the failure.

Your issue is fixed (I hope :)) in 3.039 (already published)

Sounds good.
So do u think that the issue was somehow related to EWG control? Would explain alot cause i think thats the only thing what is special on my setup and in general just rarely used.
Yes. Also I add some more protections for inter cpu communication.

Hey guys, same problem with EMU classic, when using DBW module
on low loads (until TPS reaches 80% all good DBW module controlling throttle body right…
But when I hit 100% of gas pedal it somehow position not keeping in same range (wide open 100% it’s fluctuating and then dropping to 10%)
I attached the print screen and something is not right.
I hope you can spot the issue I’m facing
You posted to wrong group. It is v3 group.
Make sure there is no check engine code dbw.
If there isnt check grounding of module and emu.
Hi. My first post here. Tuner. If someone search for similar issue I will leave this here.
Today we messed for hours with DBW power drop issue on Black.
After troubleshooting everything DBW and power related HW and SW-wise. Finally we found issue: one of four 1.8T coils was miswired. Every coil have two GNDs. One for secondary windings - always grounded separately to cylinder head, another for primary winding and power stage - usually get gnd from same place where ECU. For one coil both GNDs pins was interchanged. This injected some kind of noise into ECU wiring and DBW part in ECU keeps resetting randomly. So in our case this 100% solved issue!
Old firmware. So no usable logs. Sorry.

Thank you for posting. Very interresting case. Probably high current driven by the coil from analog ground makes a lot of noise.
