fair comment on that i guess,,,,, but what actual MPG difference is there in reality when hes gonna be on a cold start map most of the time driving to work till the cars upto temp

driving for a little longer he would be better off but hes a 10 min drive to work in the morning

thats the difference hes looking for,, will he notice that with the closed loop

motorways YES DEFFO as he drives like a pussy on motorways as he wont break 70 for fear of getting points ( yet he will do 130 in a 30 which is ironic )

its a GOOD thing for hes car,, just he needs to understand what its gonna do for him,,, its like taking diet pills,,,, they help loose weight IF you control the diet and excercise,,,, keep eating the pies and bacon double cheese burgers they you wont notice the REAL benifit

ps: thats made me hungry pmsl
