Student project using OBD reader

Here are some example data obtained from the OBD reader as was collected by one of the student groups. This is actual driving in KL. I think this is from Kajang to KLCC. Here it can be seen that the fuel economy changing along the route. At beginning of the route, at kilometers 5-10 and at 17kms there are peaks of fuel consumption (in litre/km). This could be due to traffic jams etc. Thus, if there are 2 routes available, one can compare the data and tell which route is more cost effective.




Below is the raw data of engine rpm, vehicle speed and injection pulse width. There are other data that can be monitored.


There are a lot more possible projects that can be carried out using the OBD reader. One can plot the fuel consumption along major roads in major cities and relate that to CO2 emissions. Hence hot spots can be plotted on a map.

One can also monitor the data when driving in Malaysian cities and compare the driving pattern to the adopted emission test cycles (based on European test cycles). See whether the adopted test cycles represent our roads and cities. See whether the emissions measured by the adopted test cycle over or under-estimate the real emissions produced when driving in our own cities.

One can test different fuels and see whether there are significant differences

One can test all gadgets/additives on the market and see whether they really perform as claimed.

and many more......
