i don't know if there is another way

what i did is put the arduino on the bus

in a custom pid a program a standard PID that normally the ecu doesn't answer

arduino is monitoring that request and then respond in it's place like the ecu would normally do it

torque doesn't see any difference

bump

test for some reason i can't my answer

It says there are several responses to this thread, but when I click on the thread I only see just my posts. Are there actual responses? If so can someone PM me the responses?

Hi

I would also be interested in this feature.

I would like to get oil and water temperatures from the OBDII port and the Oil pressure I would like to add through a custom PCB.

Can Torque support two Bluetooth adapters at the same time?

Bump. Anyone?

Have you looked at PLX iMFD devices? I
believe Ian has added support similar to
what you describe for these devices.

Search this forum for related threads.

Thanks.

I have done a quick search before posting, but it seems that most of those products are now discontinued?

https://www.plxdevices.co.uk/product/Automotive/Kiwi/PLX-0089/kiwi_imfd/PLX-Kiwi-2-iMFD-Adapter

It's really annoying because all I really want to add is oil pressure and nothing else.

Still searching for the answer.

you just have to send the data into the can bus with the arduino

and then read it with torque

i have done it a while ago
