Can both Arduino & OBD adapter be connected to torque same time so I can display some gauges with OBD data & some with Arduino data on the same display?

Hi!

Not yet – at the moment the arduino is instead of an OBD adapter, though if enough people request that ability I could also add it

Hi,

I would also be interested in this functionality.

I use Torque with my Cummins powered Ram pickup. Most modern diesel pickups have alot of critical sensors available, but they all seem to lack an EGT sensor before the turbo. Many guys like to monitor this so they end up installing a separate, expensive electro-mechanical gauge to accomplish this. If the Arduino and OBD II could be connected at the same time, this would make a perfect system as an alternative to expensive tuners, or adding mechanical gauges.

I think an all glass instrument display would be pretty cool in a more modern truck.

Thanks for such a great product!

Mike

Good day again.

I’ve just tested arduino uno & torque as per your example with potentiometer. Really cool thing. However update rate is about 5 pid/s. I expected faster response as I see in the code CANbus 500k is used. Should it be faster or it’s normal rate of update?

Thanks.

I would also vote to have both.

My current setup using ELM327 works great, but I also have non-ODB wideband to capture vital Air/Fuel ratios.
I currently have to capture logs separately and manually align, but would prefer having custom pid within torque.

Thanks again for all efforts on this great app!

Hi!

Ok – I’ll add this to the todo list (it’ll happen!). It will likely be as another plugin (to feed the data into Torque) to keep things nice and straightforward to use.

That’s great to hear!

Thanks in advance….

Definitively need this. I want to use Arduino to get the following data:

    Acceleration (which the Android head unit does not provide internal sensor)
    Brake sensor

This would be outstanding functionality. I run a road race car and it would be awesome to have a torque dashboard and datalogger with OBDII and miscellaneous sensors added in.

Personaly

what i did in the past to log value with arduino and torque

i was using a standard PID that the pcm would not respond 90 in my case

and i was letting the arduino respond to torque

torque didn’t know any better

i was inputing my pressure sensor voltage

something like this

Is this already possible?
Anybody tried?
Would be cool to monitor aftermarket stuff.

like i said .. you can easely do it with an arduino

i did it in the past

you just need to play a bit with an arduino obd program

i just used a standard pid adress that my car was not responding to

and the arduino was responding instead

torque doesn’t see the difference as long as somebody answer the request

Want this too. Ideally you would be able to run a OBD reader and multiple arduino connected devices.

personally i was using an arduino to insert value into the can bus

before it was an option over here

i used a can bus break out ..and used an address that the car would not answer to … and used the arduino to reply instead

torque was not seeing any difference

+1

A plugin or app feature to allow this would be fantastic

Please add this feature. Many ECUs do not provide sufficient data for engine monitoring. I made an Arduino adapter to add oil temp, pressure as well as transmission temps, battery voltage(s!) aso. This would really add a lot of value to the app.
