DiscoWagon Posted September 24, 2007 Share Posted September 24, 2007 Does the accuracy of this feature change when bigger injectors are installed? I used to have an Audi A4 1.8T and the calculations were quite off after putting larger injectors. Just curious. Link to comment Share on other sites More sharing options...
rao Posted September 24, 2007 Share Posted September 24, 2007 It does, the chip bases its calculations on the stock injector size so it will be very optimistic As far as I know there is no way to change it.

SnowBound BP5 Posted September 25, 2007 Share Posted September 25, 2007 Haha but honestly why would you even be concerned w/ fuel economy if you opt for larger injector? After I dropped in those 1300cc suckers I lost any right to even squeak out a complaint! Link to comment Share on other sites More sharing options...

NSFW Posted September 26, 2007 Share Posted September 26, 2007 There's a setting the map to tell the ECU what size injectors are installed. I suspect that if you install injectors that flow Xcc, and tweak that setting to Xcc, the mileage display would not lose accuracy. Haven't tried it myself though.

They are unrelated; the MPG display has does its own calculation. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
