I've been calculating my fuel use vs trip meter in my modified BFII lately. Quick listing:Fills done to the first click, trip meter reset to 0. Fill to first click again.368.5km - 44.6L - trip meter says: 10.2 Actual = 8.26166km - 20.71L - trip meter says: 10.3 Actual = 8.02167km - 28L - Actual = 5.96 (didn't write down the trip meter here)These are on highway cruises (100km/h) with a few traffic lights, and some hill driving at 80km/h.If I put my foot down it's not nearly as good of course I have had very simular results with our BFII xr6 turbo, the trip computer is pesimistic, the best I can manage on the computer is about 10.2 outside the city, but work it out the old fashioned way and its usually in the low 8sInteresting to note too that my missus has noted that on the same work comute for 5 days it seems to use within a litre per week of her subaru liberty RX 2.5 auto that we just got rid of, so the XR is cheaper to own and run because it dosent need fixing.....ever, unlike the subaru.

Before tuning it was about 1L/100 over the actual use. No idea why... Edited 26/10/11 06:02 AM by -SteveR- Link to comment Share on other sites More sharing options...

If it's not 100% or busted the reading may be off and fuel consumption could suffer. As for the tune, it's not going to make any difference in closed loop. The ECU has short and long term trimming which will always try to achieve best possible A/F. Link to comment Share on other sites More sharing options...
