2008 LS Swapped Puma Instrument Cluster
Hi,

I'm working on finishing 6.2 L92 Swap with BMW ZF Transmission for 2008 110 2,4 Puma.
I'm running MaxxECU Race for the engine, so I can design and send custom CAN messages to make rest of the electronics happy.

Can somebody share or guide me to information about CAN Protocol in 08 Puma to make instrument cluster work?
I have the warning ligts working but RPM, coolant Gauge need something more. Also any other information is welcome if A/C and ABS require something more.

Edited: TD5-Puma confusion.

I'm pretty sure that the gauges aren't fed from CAN - the speedo head is fed with analog outputs from the ECU, which the speedo then uses to drive the gauges.

Easiest solution would be to run the gauges directly from standalone sensors - most people choose the VDO cockpit vision range which are a close match to the standard gauges.

I'm confindent that the speedo is CAN controlled. Engine light, battery charge indicator, glow plug indicators are already working at 0x127. Without any input the temperature gauge dial is maxed. With right bits I can make the gauge go to 0 position (possibly to do with some malfunction flag?)
The tachno seems to be 0x0F6 but I'm unable to get indicating.

I'm not a LandRover specialist but it seems to be the Puma instrument cluster. There is also a CANBus controller for some OE applications:

The TD5 instrument cluster is not CAN controlled, but the Puma one is...

@Martin on here has a CAN controller for the Puma cluster I believe, so may be able to advise on the CAN messages required...

Okay, thanks for the clarification! It used to be 5cyl turbodiesel. Not really familiar with all the naming.

Does the cluster look like:

Or:

First is a puma cluster, second is TD5. If the engine had a 5cyl diesel and the first cluster, then something else has been swapped round to start with - it's not standard...

Okay, This is a bit embarrassing but yes, it used to be 2.4 4-cylinder Puma and yes it has the Puma cluster. Laughing
Anyway- question is the same.

this might help:

https://github.com/posmanet/DeCANder/tree/master

If you look through the code within the project (the .ino file), there's definitions for most of the CAN messages which you could reverse engineer..

eg:

if (canID == 246) {
rpm = (canBuf[4] - 96) * 256 + canBuf[5];

RPM is 4th bit of message 0x246, offset by -96, multiplied by 256 + the 5th bit?
