    Oh it gets worse. I was around 18/100km in my LSA. Added the Walky W557 kit. Now in the city about 27/100km. It is going back to the tuner this weekend as they expect around 18/19. Needs the short fuel trims adjusted at slight throttle which is city usage. On the freeway it isn't bad. Lord knows what it would do if you tracked it. Car itself goes like a missile.

    Any level of fun going up the range will certainly suck it down.

    Yeah, I’m think my MSE has some fault with it; possibly has a big hole in the tank where fuel sloshes out when having a little (sane) fun on a quiet road ;)

    Good question, whatever the default is I haven't changed it I'll have a look when I go out later today. However, if it was on 25kms would that mean I'm getting 24.4 on a long run, likely not or at least I hope not...

    Seriously though, I think its the same it just measures the economy over a that last 25, 50 or 100km and as I'd travelled about 700km carefully and with cruise control on along the Hume I don't think it will have any bearing. I'll give that a try on my next long run.

    On a run from Mindarie to Baldivis and back yesterday, a total distance of 170km, mainly freeway driving at 100kmh the MSE made 8.8L averaged over 100km. By comparison my ‘94 LTD (6 cylinder) does 11.2 under the same conditions.

    Yes it measures on the last 25, 100 or 500. I was trying to work out what you meant by 24.4 now I get it. EG 25 would be 6.8l/100km

    With cam installed, fuel consumption rose by 2L/100km in all situations except idle, which rose by 1L, from 2.1 - 3.1

    Not at all unhappy about 9.5L on the open highway.

    My vf2 idles at around 3.2l/hr and drops to around 2.8 after driving for around 2-4min. Is this similar to what others are seeing, im getting less than 400km (~380) to a tank, granted its quick trips (less than 10km) 90% time, but concerned something not right as i used to get 450-500km. Highway driving different story average around 7-8l/100km. Car is not cammed but tuned (basically w375)

    Interesting, mine was same, now with cam added to W375, it idles in neutral at 3.1l/hr and idling in drive (braked and not moving) at 3.8l/hr. I still get 440 on highway and as low as 300 in town, but with 422kw it's a heavy foot and fun for me.

    I still think it might be best to follow other advice on here and get a second opinion dyno run, something seems a tad off, but I am certainly not the best at interpreting those types of results. But, how can you not use the V8's potential, the byproduct will always be liberation of hydrocarbons....!

    Exactly! I didn't buy V8's for their economy, I bought them for their 'consumption' and the amount of 'smiles per mile' they bring.
    Although on the highway they are fairly economical considering how much grunt they produce.
    And they're hard to beat in 'overtaking power'.

    VF II SS Redline ute...

    Peak hour run to work and back usually get anywhere from 15.5 to 17 litres /100km over the tank. Best I've had so far is 10 litres/100km on country trips at 110 km/h. City average speed is very slow, 29 to 34 km/h. All the idling just kills any hope of good econ!

    Yeah, I get much the same... stop start is the real killer for fuel consumption (as is the desire to hear and feel the motor :rolleyes: )

    It gives the fuel consumption averaged over 25, 100 or 500km. Not as a figure that you need to multiply.

    Most of the kms I do in my my17 vf2 redline ute are around town, get anywhere from ave 12-13l if I don't give it too much stick and then to 17-18l same driving scenarios but with a bit more "spirit". Only longish (~600kms) trip ave was ~9l.

    Just out of interest.
    For people who have had the intake, exhaust, headers and tune.

    How much did it improve fuel economy?
    I’m tempted to go to MorPowa later in the year and get that fitted. I’ll be adding a few k’s to the car (auto).

    Just getting some fuel economy information to sway the other half :)
