OBD reader new update





The OBD based dashboard extender for PROTON Campro engine was squeezed into small electronic hobby box.

I read recently that someone managed to get Scangauge to work on PROTON persona elegance. He mentions that the new Scangauge has updated firmware and should work with Campro based engine. I certainly have doubts as it was unlikely (in my opinion) that Scangauge people would consider upgrading their kit for such a small market. My feeling is that, it is the new PROTON ecu that is compatible with OBD2 protocol. Note that the new Persona has new 32bit ECU, unlike its predecessors.

Thus,I still think the kit shown in this picture is the only one that works on older EMS400 and EMS700 ecus....; ). I can also change the codes for use on Perodua MyVi.

Things that can be shown:
1. engine rpm
2. throttle position
3. engine coolant temperature in degree Celcius
4. intake air temperature
5. Injection pulse width in milliseconds
6. intake manifold pressure
7. oxygen sensor correction factor
8. load (this is actually volumetric efficiency)
9. oxygen sensor voltage
10.Battery voltage
11.lambda adaptation 1 and lambda adaptation 2 (I am not sure what these are, but are available from the ECU data)
12. fuel consumed in liter (calculated by my own calculation)
13. Fuel economy in litre/100km. This is average fuel economy.(calculated by my own calculation)
14.fuel consumption in km/liter. This is instantenous data. (calculated by my own calculation).

The display can be in the form of digital values and also simple horizontal bar graphs.

The new source codes also assists for acceleration tests to be carried out. (Passby and standing start acceleration tests). It prompt the driver to execute the tests and automatically measures and display the data.
