I just bought a PDM 15 to use with my fueltech 550. I downloaded the CAN config file and it works great, ive got the PDM running all of my outputs based on the CAN inputs in that file. However there are a couple data fields that the can input file doesnt include that id like to add to the PDM. Namely id like to read the Trans temp from the fuel Tech CAN network so i can have the PDM control my trans fan. Fuel tech manual has the CAN information for that data, I just have no clue how to understand it and actually add it to the CAN inputs. Is there anyone that can help? Im not sure what information you would need, but i can post the stuff fueltech has on their manual for those data points.
thanks!
Hello George and biohazarde,
some days later, but maybe you haven't found what you need.
The FTCAN2.0 data streams are very flexible and the content of a stream depends highly of your configuration inside the ECU.
So signal you want can be the first value or can be the 10st value in the stream. And this will be changed if you change the ECU config.
Appending you can see some testing. For example the 0x140012FF multiplexed message will change it's content depending on changing the input configuration of the ECU.
These for CAN logs of four different ECU configs.
To read the FTCAN2.0 is more difficult then normal CAN message. Georg, you need a additional transport layer to read it. I have a GIThub repro with a STM32 project to do this.
