Extended CAN ID (29-bit) capability with M142

Postby heavydiesel on Mon Oct 14, 2024 11:56 pm

Hello,

I have an M142 with Diesel firmware, and I'm looking to control a variable geometry turbo via CAN. I have reverse engineered the CAN position commands from the OEM ECM and the feedback positions from the VGT. Currently, the only options for VGT motor output are full bridge. I understand I would need a development license to program in CAN control, my main question is, is it possible to use Extended CAN with the M142? It seems, from what I understand, it is setup to use 11-bit CAN identifiers only in the configuration I have now.

If doing 29-bit CAN ID communication is not possible with the M142, is there a CAN I/O device that I could use as a middleman to translate messages between the M142 and VGT someone would recommend?

Thanks!
