I am using exactly this version v191.

I just enabled temp sensors and thats all what is changeed.

I am not programer to know read program code well and it would be very nice if you tell me where can I find those tracking of miles/km or the tracking of fuel quantity values and describe to me how to shange it.

Just show tank distance and tank fuel used used on screen.
Wich of them is wrong?

antonamp2010 · 07-14-2011, 05:44 AM

tank distance with full tank is around 800km
tank used 59L

from my calculatio consumption is less than 7,5 L/100km. In the city this consumption should be bigger around 9 L/100km

But why this value decresing with time while driveing. When I stop with car average cons is bit increaseing but when I go forward it is decreasing again.

I do not know what to do to fix it

59l and 800km is from car odometer?

what numbers are shown in OBDuino (km and L)?
average is calculated from distance and all fuel used. one of them is wrong in OBDuino. which one?

antonamp2010 · 07-14-2011, 05:57 AM

kilometers are from car odometer. Maybe I made misktake in calibration?

I filled up my thank and put that value in THANK USED in obduino
after some thime when I wasted fuel I just read car odometer and that value (800km) put in the TANK DISTANCE in obduino. Is it wrong?

Can you describe how to calibrate obduino?

Set Tank distance back to zero, and Tank used zero too.
Do not use them unless you why and how to use them.

They are for used part of tank after last fill. not for "full tank values".

Just use "Tank size".

And do not forget to reset tank trip after next tank refill. (LEFT and MIDLE buttons pressed together).

OK I will try that and inform you about results.

Thank you anyway.

Hallo again

I have tryed everything you said. But nothing is changed. I set fuel% on 100%, tank dist on zero, Used tank on zero and when I start driving average consumption goes from 99L/100km and falling down to 3-3,8 L/100km for a 3-4 km driving distance. It is easy to see instant cons showing 6,5 L/100km and average cons shows 4 L/100km and falling.

Anybody had the same problem?

Which program version is tested by you and working well, Maybe program is faulty?

I am using version 191
