Thread Revival.
Its been 6 months, and some 15,000miles since the remap ( i drive alot).
My mpg is still really low to how it used to be, in closed loop driving (i.e, light footed, not Wide Open throttle). i've kind of learnt to live with it. but the confirmation came during the Wales meet a couple of weeks ago, a couple of us convoyed from London, so on the walkie-talkie i asked the guys to reset their trips.
i was 3rd in a convoy of 3 - so wasnt setting the pace, and was keeping an even footing
going through north london and north circular, with lots of roudabouts and lights, i was 20.point-something, whereas a DE and HR i was with were both quite close to each other, in the high 20s.
maybe not the best test. so when we hit the motoway and were driving a little more sensibly we reset.
They were on 34-35mpg at steady driving (to suit traffic. 60-75mph). One of these cars was Bradders, who those at Wales know hes lost at least 1 valve seal or oil ring the smoke from that thing, cor!
me, i was on 25-26mpg!
thats huge.
My exhaust has since the remap always smelt of unburnt fuel when leave the drive / parkup. but Bradders made mention on the trip that when driving behind me, it was quite strong. Yes i have sports cats, but unburnt fuel isnt a symptom of sports cats.in fact it will kill them.
10mpg. thats some heck of a figure thats now been proven in a comparison.
having spoken to other remapped Z's during recent meets, it seems i'm not the only one with the issue. but, not everyone has the complaint. seems odd that some of these results seem to be polarised.
So, now i know its not a magical-overnight-heavyfoot-syndrome, i'm going to be looking at getting this re-remapped.
