Looking to run traction control setup with Fueltech FT600, is it possible to run the sensors to the PDM directly or will they require a pull-up? Then from there send them via CAN
The PDM inputs can only measure absolute voltage and not the frequency of the input signal. This means that the PDM wont be able to detect wheel speed on its inputs.
First point: there are differnet types of ABS sensors. Which one do you use? Inductive types? Hal Types? With or without direction detection?
Second point: There is no way to send any data to the Fueltech ECU. The only possibility is to simulate an Fueltech device. But then you need more knowledge. And there are only two Fueltech devices which can send a wheel speed value. Maybe it is possible to emulate a OEM CAN device. But then must be the PDM on the 500kbit bus.
Original ABS Sensors are inductive, I have not found a set of hall sensors as of yet to try. But the car is not using anything ABS or any oem device soley using the ABS sensors to detect wheel speed and have the fueltech make the adjustments as needed. I'm a bit confused then, so the PDM25 can not send information to the Fueltech via CAN? The reason I wanted to run the ABS sensors to the PDM is because I am not 100% sure the Fueltech can read the inductive sensors without an additional converter
the pdm would also need a converter, you would also need to mimic the fueltech input expander to send data back to Fueltech. This is a Fueltech limitation.
I'm not sure what the input polling rate is on the inputs, I'll look and see if it's anywhere in the docs. That could be bypassed with signal converter but lose resolution. Are you wanting the PDM to send the signals via can to the fuel tech?
I thought PDM 25 have selectable pull down or pull up. I think it would need to be pulled low in idle state.

maybe have a look at this, it seems the FT can do it without having to involve the PDM.

i would run the sensors to your FT600 and put less critical sensors on the PDM.
