Corrupted firmware PDM 25 V2

I don't see any firmware downloads on your website. Can you give me access to them? Additionally, the instructions that came in the box appear to be for the V1. The directions I found on your website Version 1 - 23/6/25 also appear to be for the V1. Are there new instructions for the V2? I ask because the windows on the V2 don't looks the same as in the instructions.

Fuel Pump Configuration issue on PDM25

I have a Fueltech FT550 - Pin 9 (blue) from ECU connector B goes to PDM connector A7 = Input 1.

On PDM25 connector D10 = Output 24 (25amp) goes to Fuel pump.

Output 24 set up as:

Button 2 on Can Keypad set to Latching

Would this setting for the fuel pump Input be ok?

Cooling fan wiring and operation for drag and drive build

Currently planning and wiring up a PDM28 on a drag and drive build. Curious on success wiring up a cooling fan. Using a FuelTech 600 and 15 button keyboard. Ideally would like the fan to run off coolant temp from FuelTech and be able to use the button on the keypad as an override for cooling in the pits. Thank you for the help.

Yeah shouldn't be a problem. Just set up the CAN from the FT to the PDM. Then use the CAN variable for coolant temp to turn on the fan. The output function would be something like -

Output on if

CAN input variable (clt) > 80

Or

CAN keypad 1 button 1 (fan ovr) state equals true

Where is your CAN input water temp value coming from? Also what is the output logic function

Hi, unfortunately the V1 PDM25 is not compatible with the pro software.

PDM25 causing can bus issue

I have several devices all happily communicating on a can bus. The PDM25 is one such device on that network. Whilst the PDM is powered ON, the traffic on the network is all fine. I can scope the traffic and see the waveforms are well formed and timings correct. However, if the PDM is powered OFF it takes down the network with it. The waveform is completely suppressed to zero, it vanishes.

The PDM is NOT configured with a termination resistor as the network already has two nodes configured with this, and the bus resistance is the required 60ohmns. Why is the PDM disrupting the network like this?

All other devices on the network can be powered up/down independently without disrupting the network. With the PDM off, it must be physically disconnected from the network before the other devices can operate again. This certainly isn't correct or expected behavior f…

Any thoughts? Devices on this bus must be able to be powered up/down independently without effecting the bus. This is a show stopper for us.

Automatic fuel transfer

I want to setup an automatic fuel transfer using the sensor calibration (FUEL_LEVEL) input. My goal is the fuel pump turns on when the calibrated fuel tank level reaches 4 gallons and off at 9 gallons. I am using the counter to make it work but is there a better way to achieve this without the counter?


on if


CAN keypad 1 Button 4 state equals true

Thanks

you could possibly get a similar result using generic functions. on if equal to or greater than 4. and value is less than 9. that way the value is true if it's greater than or equal to 4 gallons. and on if its less than 9. they're for keeping the level between 4-9 gallons

Hazard lights configuration

I'm strongly considering using a PDM15 with my project car but I have a question regarding items which always need to be functional regardless of the 'ignition 'state' of the car. As I understand it, it is not recommended to permanently connect the PDM15 ignition input to +12v as this drains the battery over time. Is there a way then to program the PDM15 for a hazard light function without the ignition terminal being connected to 12v?


Thanks,


Trevor

for a simple task of hazard signals its probably best to just use a flasher relay. but i needed power steps to come out and be controlled by the pdm i just used a relay and diode to trigger the ignition on for the pdm.
