Can now leave in gear on lower revs and reduce number of gear changes, also pulling smoothly throughout rev range ? Just need to fit new tyres on the front wheels to further improve mpg! Improved to 64.8mpg ? 16.5% better.
Ian,Nissan Micra SR 1.5i
I’ve had 5 Tunit devices over the years . 4 were in new Nissans with the Renault 1.5 diesel, and as they were hard wired sold them on fitted. This Optimum Plus ,which I’ve only ever used for five years in a petrol Nissan Micra C+C 1.6 Essenza ( one of the first made in 2005), again, has amazing results. The car consistently does 45mpg , is incredibly flexible (in 5th at 30 mph on the flat on a trailing throttle )..in Sport Plus. Using a maximum of 6,000 rpm when fancied, for a car probably only worth £2k , it seems quite sharp! A bit of a Wolf in Sheep’s clothing. I only use Shell V Power and scrupulously keep on top of the servicing, even though it only does 3,000 odd miles a year. Once again, thank you for your kind assistance.
