Arduino + Torque app = Motorcycle RPM??

Projects General Guidance
1

So, I have one old Kawasaki GPZ900r (1993) and I would like to use my Samsung android tab as a speedo and tacho.

Speed is easy as that would come from GPS (I guess) but RPM is little problem as Im totally noob in Arduino!!!

I did find this topic -> Tachometer Project - Project Guidance - Arduino Forum

but will this apply even when my goal is to connect Arduino to Torque app?

There seems to be support directly from torque app to Arduino

https://torque-bhp.com/wiki/Arduino_code

but there is also other way by simulating ELM327

what would be best way? later I would like to add oil,battery,fuel and so on.. but now im more interested about this RPM.

As I understand it, the app requires an OBD2 diagnostic system on your bike, quite unlikely with a 1993 bike. You may find information about adding sensors to your bike in a Kawasaki forum.

Hi;

I've recently created a lib to emulate ELM327 on an arduino.

You may use it to output data to torque.
