Thanks to everybody, who has beem developing this product.
I have used my arduino based mpguino now for 327km and still need some fine tuning with the calibration, but I think I'm quite close already.
I was really surprised about the ecodistance (distance without injection) and the fuel used at idle.
Ecodistance = 17,1 km
Idle Fuel = 2,6 Litres
Have I really gone 17,1 km without any use of fuel?
I've always thought that the engine braking does'nt make much difference.
Have I really spend 2,6 litres just idleing at traffic lights? Maybe the Start-stop automatic in the new cars is not so bad thing afterall
One small improvement to the mpguino I would like to have though,
My instant L/100km reading is not steady. On the highway at steady speed it's showing 5,70...6,10...6,30...4,90...5,80...6,30...5,10 L/100km.
Is this normal? How about others? are your instant readings steady?
Would it be possible to have some averaging on the instant reading? Maybe take samples of every 2 seconds and display average from that?
I have studied the code already quite much, but I still don't have the skills to do the averaging stuff.
