Spaceman Posted October 6, 2009 Share Posted October 6, 2009 Yeah im gutted about the fuel consumption on the 3.5 litre petrol engined sports car thought id get at least 54 MPG rather than go down the route of the monkey valves and special £3 tuning chips im having a 1.6 Hdi engine fitted instead Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 6, 2009 Share Posted October 6, 2009 best way to improve MPG is weight saving, so i leave the wife at home only kidding lucy i love going for a drive with my wife and shes only a small slip of a girl she'd be better off driving my car and leaving me behind, i'm the weight issue in our house Quote Link to comment Share on other sites More sharing options...
andlid Posted October 6, 2009 Share Posted October 6, 2009 after I got my car retuned it now gives me: 10.2 km/l instead of 6.4km/l... need to do a few 'normal' drives to get a more accurate consumption but it looks awesome! motorway cruising (130-140km/h) I had 14.4km/l !!!! amazing!

captain Posted October 6, 2009 Share Posted October 6, 2009 What do mean "tuned" I average 8km/l since purchase and 10 km/l sounds lovely. Please elaborate! Quote Link to comment Share on other sites More sharing options...
andlid Posted October 6, 2009 Share Posted October 6, 2009 What do mean "tuned" I average 8km/l since purchase and 10 km/l sounds lovely. Please elaborate! eh not entirely true. When I first got it with std ecu I'm not sure what mileage I was getting (never bothered checking I think) now when I've got Haltech platinum 350z ecu I got it tuned with E5 and (ethanol 5%) it gave me the pre value and after I got it retuned (last week) I now get the new value. # it might be due to three other things too: (making the egine easier to breath) new Kinetix SSV manifold new BERK cats new custom 2.5"*2 exhaust system. (two pipes from catback) The tuner did make it a bit 'lean' (I think around the normal driving conditions for me! lovely!) Need to figure out how long it will take me before I actually make back the price for the tune Quote Link to comment Share on other sites More sharing options...
