Hi team,

Whilst not technically new to PCLink in general I am struggling to get my head around the CAN setup section.

Is there a tutorial on converting the hexadecimal figures that a CANsniffer the likes of arduino outputs into the multiplier/divider system that the Link uses?

The Link help file has very limited information on this topic and I cannot find much information in my research.

I say this as im just about to begin wiring a G4+ Thunder into my RX8 and would like the Link ECU to replace the OEM unit to retain control of all of the functions of the dash and ABS/DSC systems ETC.

Adam, when he was at Link was kind enough to add some functions to a map to get most basic functions working on the dash, however I would like to expand on this for more functionality eg: odometer, cruise control light etc.

does the G4+ software tutorial cover CANBUS in any of the modules? I have no problem buying the course and intend to, once the wiring side has been completed.

There is a thread in the Link forum with some background info regarding this project.


I saw your post on the Link forum but you didn't actually ask any question there. If you want help it would be best to ask your question there to keep it in context. The G4+ software course doesn't cover any CAN bus reverse engineering. You can use windows calculator to convert between Hex and decimal. Use the test calculator in PC Link to see how the multi/div/offset effects the raw value.

The RX8 CAN map I attached to that post should make most of the car work. From memory the only thing that doesn't work is the odometer. The G4+ ecu does not have a distance channel so the is no way to generate the odometer tick. Cruise control light should be no drama, originally when I done that map it wasn't possible but we have since added cruise control light functionality to the G4+ firmware.
