Ranger Mods

Took some time to achieve and I will implement it once some more work has been done.

Reading battery voltage for my bench power supply and showing as a PID on the Ultragauge. It would also work on a Scangauge.

Voltages will be slightly out at the moment due to some resistors I have in play.

I need to order some components now so I can have a second battery voltage PID and current PID.

Yes, the others are showing err due to it being on my bench and not plugged into the vehicle.

Had a bit more of a play.

These arduino's are not a bad little item. They have no problem acting like any other canbus module in a vehicle so nearly anything is possible.

I'm emulating state of charge, alt current, amps i/o and a second battery(custom non existent PID) on the Ultragauge and it is smooth as silk. I see no reason why 8 or more gauges won't work.

This would work for Ultragauge, Scangauge, OBDlink, Torque. Basically any device or software that supports custom PIDS.

So Thinking;
2nd battery voltage
2nd battery current in and out
EGT - Pre DPF
Fridge Temp

Anything is possible. You could get a relay to trigger based on a canbus message that is happening with the vehicle for instance.

These things are so quick to boot that you just let them completely turn off with the ignition. As quick as a UG or SG will boot this is back up and running, waiting for a device to request data.

One bonus could be is that we could pull canbus data that is always running on the bus that may not have a PID and a UG or SG could access it. Not sure what data at the moment as I have not thought that far.

That is awsome (and the arduino too lol ) I tinker with arduino to And am working on a tvms at the moment . Is there any chance you could share your code and schematics for the arduino ?
