opvaulet said:T6, Looking forward to your results. Which model do you drive? Mine is a E34 1991.
opvaulet said:T6, Really? Can't be as high as mine. 68 litres, 500kms! Anyway, E39 525i is a beautiful car. Mine's in great shape everyway except FC.
yky said:No appreciable diff in fuel consumption. Was doing about 9.5 to 10 km/litre both before and after ecotek.
The thing about the ecotek is that tuning it is not easy and is very subjective. Depends on the sound that emits from the gadget when it is turned by hand. It appears that the type of sound that emits changes over time and is not consistent, therefore making tuning extremely subjective.
