Fuel & EGT issues what will fix this
Hi All,
Over the past 12 months I have added a heap of after market accessories to the 2012 GU8
The heavy items are,
Bar, winch, duel battery, 75lt sub tank, 33" MT ATZ3 x 5/285/70/17 with 45PSI, 2.75" exhaust.
My town driving fuel has gone from an average of 13.5lt to as high as 18lt per 100 with average 16/17lt per 100km.
Did a trip of 360km on the weekend to Tallarook on a 4x4 course (for my daughter on her L's) and fuel is 23lt per 100, including to and from.
It was very slow going with a huge amount of stop start on the course, slow going and revs kept low (which would not of helped).
What is the best option to help with high fuel, map or chip and from experience from others here, which one?
I know driving these at higher revs is best to get the motor in the sweet spot, but this is not always an option.
I feel the performance of the car has gone backwards and would have though so with the extra weight but not as much as it feels.
Still good on take off just a slug up long highway hills etc. Low range is perfect as its in the rev range etc.
The EGT temp is around 350 deg C on the flat and can climb as high as 500 up long hills.
In low up hill it was on 620 Deg C, is this normal? How can this be reduced and will it cause any damage at high temps?
I fitted the EGT/boost gauge after all the mods, should have done before to get pre readings.
Any help would be great, I need to get this sorted before we head out for some remote touring.
