CAN wheel speed on G4+ PNP R32GTR

Recommended Posts

I have a G4+ PNP and have wheels speeds available on the can bus and have setup the stream in the G4+ and there are no can errors.

The wheels speeds are all in a single frame, bosch give the can protocol details: starting at position 0, 16bits each wheel, "intel" format (LS First in Link lingo I think),  with 0.015625 as "factor" (divider of 65 I guess). I have set these to link to the built in wheels speed parameters.

After a slow drive around the block I get no signal in the link for right rear wheel, or bits 48-63. The ABS is seeing a speed signal so I assume it is presented on the can bus.

The CAN setup UI looks a bit odd with LS first byte order, it highlights the wrong bits in the view at the bottom. In this case bit 48 and bits 56-63. So if this is to be believed, it won't be reading the least significant bits 48-55. Is that a real problem with LSB/Intel byte order or just a display glitch?

 

EDIT

Ok I think I figured it out from this other thread 

 

LSB requires setting the "start" to 7th of the 16bits for each parameter, I can't make sense of that but I'll try it.
