PDM 25-V3
I have a mechanical fuel pump and an electrical primer fuel pump.
Is it possible to have a timer for the electrical fuel pump that starts on button and then only run for 20 seconds in case i forgett to turn it off??

Hi
Just getting started with evaluating the PDM28 and have a question. Is it possible to have more than one PDM28 on the same CAN bus? If so, how do I change the CAN ID of the PDM28 units so they can coexist on the same bus?
Thanks
Simon

Just started getting this PDM 25 installed and running. Google search has not come back with an answer but all my inputs show up at 6.00v and they are 14+ ish actual. What should i be looking at to correct this?
THe original units measure 0-6V. You can still program all your logic, apply battery voltage, but it will only show 6V.

I have an idea to enable the use of an Estopp electric parking brake actuator via the keypad instead of the button and control module that comes with it. The actuator only has two wires so I am assuming that the parking brake control module reverses polarity to the actuator. There is no limit switch or anything that would break the circuit so I assume module turns off the power to the actuator based on amp draw or based on time. My thought is that I can wire up two relays with each one providing ground to each wire to the actuator in the normally closed position. Each relay would be on a separate output in the PDM. Then when I activate one output or the other to apply or release the parking brake, it will provide power to one of the relays and energize the relay at the s…
I just did this. If u have a pdm 28 the outputs are reversible and make it super easy. And I used a combination of on time and amp so that way if it dosent hit amp cut it will still turn off the output. So basically u can set a line of output on time is < x amount of seconds and output current < x amount of amps super easy holes this helps

Trying to get my PDM loaded with V1.2.3, I'm getting the "Device is not responding to the Bootloader". Any help would be amazing.

FT600 and Hardwire PDM.
I have wired the components per Fueltech's wiring diagram for brake switch, line lock, and transbrake. Is it best to wire an output from Fueltech to a Input on the Hardwire PDM to control all the functions? Any other suggestions on wiring is appreciated.
IDK if you can get the PWM duty thru can, but if you can, instead of using a SSR, use an output driven by the PWM duty readed in the can bus.
If not, maybe you can figure out how read the PWM duty with an input in the PDM, and drive the output with that value.

CAN outputs issue:
when I set the last output to be larger than 8 bits, it becomes impossible to revert (permanently greyed out). Deleting the CAN message does not reset it either.
If the configuration has already been saved with this mistake, is there any way to reset a CAN message similar to the non-pro version?
Thanks

I have a PDM25 V2 and I am passing my inputs from my Holley Terminator X to the PDM. I have the "canned" functions of the Terminator X working good, but none of my user configurable inputs seem to be working. Does anyone have any advice? Just in case it matters my car does have a Pro Dash and an IO module as well.
It sounds like you’ve got the core functions working well, so the communication between the Terminator X and the PDM25 V2 should be fine. The issue with the user-configurable inputs is often related to mapping or setup parameters.

has anyone tried to send an encoder signal to a pdm? I am not for sure if the PDM can even read the square wave signals produced by an encoder. i know i could send an encoder signal to a arduino and then through a dac to create a 0-5v signal or to a arduino and a can transceiver to create a can signal and then take either or input and control a dc motor to move to set location. but was curious if anyone had any insight on whether or not you could send the raw encoder square wave signal to the pdm directly and decode the position.
It could be possible, but please could you send a trace of the signals for the encoder?
Yes you would do
Output on if
Input x on time < 20s
And
Input x status equals true
