2nd Apr 13 i have been running my ’59’ c-max 1.6tdci 110bhp with your gismo fitted to the injectors for nearly a year now. i have tried the various settings and, whilst i like the power of ‘4’, i find that the driveability i get from ‘3’ works better overall for me. i can gentle along in a 30 limit in 4th gear or a 40 limit in fifth which i can’t do with the other settings. if i have a journey to do then i try to keep the revs above about 1750 which gives me the pull and the economy. overall my mpg has gone from about 49 before installation to 54.2 using brim to brim method which is fairly closely matched by the on board trip computer. the question i have for you is:- do you have the torque / power curve data or graph for the different settings so i can see the ‘science’ in support of my experience. this may help me fine tune my driving style. much appreciated. nick m
