I just bought an Autool X60 obd gauge to monitor my temps. It works as expected. However, if I set it up for a 1300cc engine (there's a setting) the fuel consumption meter shows abnormally high readings (40-50l/100km for a spirited drive around the city)

I guess it has something to do with the way a rotary works, maybe because the plugs fire thrice per revolution? I wonder if I should set it up as a 400cc engine for more accurate readings.

Any ideas?

 

Try a 2.6l... that will be closer to reality

 

I believe that will show even higher numbers. I have it on 700cc now and it hovers around 20l/100km

I'm gonna try it though.

 

It seems that the fuel consumption is indeed too high as the car does not go into closed loop see this thread
