    My thoughts are, Prado's weigh 2.5 tonne on average, have a smallish 2.8 litre engine, with a 6 speed auto. All that is fine, but the moonshot gearing is the problem.....way to tall for that engine to carry the weight. Top gear i think should have the engine spinning at around the 1800-2k rpm at 100km/h........If i keep ours long enough, I'd like to investigate lowering the final drive ratio before any power mods, would make a massive difference i reckon.
    Cheers.

    I don't think low range is all that low either so could you just opt for diff gears


    That all said if they want heat to clean the DPF we'll load at low rpm will do it

    Well, 7000km's after the ECU upgrade and after using the car no differently (well, actually, I've left the 30kg's worth of recovery gear out of it for the past 2000km) my computer is showing an average of using 0.6L/100km more than it did before the upgrade. Seems fairly similar according to some on here.

    I wonder - does this change the official ADR rating of the car? Or (I suspect not) does the testing even run long enough for a DPF burn to occur?

    Yes my is the same using 0.5l of diesel more than before. Not happy with this.I will be writing to Toyota with complaints ,and suggest everybody effected do the same.
    This is very good reason for class action if not resolved to our satisfaction.We were mislead about the car real fuel consumption when buying

    Hi all,

    Just got my 2016 (I think Mar build) 20k service done on Thursday, had the ecu "recall" done as well . Didn't know until I picked it up. Asked what's this and the response was it was to adjust some parameters with the DPF. Didn't dig too deep into the details but it seems to be running smoother. Who knows if that's the cause but I guess it's a wait and see sort of thing. Can't say I'm too happy with the fuel economy either. It's around 12/13 as well but I think that's just my leadfoot wife!

    Just got the reprogram done today at 50k service. First impressions: idle down to 800 from 900rpm; flat out acceleration from lights showed over 90L / 100km (I have never seen such figures, even towing a 2.5t camper) ; seems to show lower L / 100km when at cruising speed; seems to lock into 6th nicely.
    Time will tell if it's any better overall.

    Toyota did my 2016 Kakadu (July build) today in its 40k service. Noticeable different in power and gear shifting. I complained to Toyota at 20k service about the gear changes particularly going from 5th to 6th (or more like the lack of it wanting to change.) At the time they didn't really want to hear about it and made up an excuse that it was normal.
    With the ECU reprogrammed it changed much smother and earlier.
    I've never reseted our mileage since new and our average over 40k is 10.1/100. That's with no extra accessories added to the vehicle.

    Had mine done at 58000km around two weeks ago. The fuel consumption is now 11.6L, about 0.5-1L more than before. Only had Deluxe bullbar, spotlight, Thule cross bar on the roof and Cooper AT3. 40% suburb road, 30% Adelaide hill country road and 30% freeway roughly. Probably the update is more for city driving??
    Not impressed with the mileage but It does seem smoother than before, especially after dealer's car wash?? (CMI ADELAIDE CBD) I always find it quieter after I do a thorough wash at home. Can't understand how it happens.
    About occasional black smoke, the dealer said it is normal for a diesel car. So I will see if the frequency gets higher in the future. So do I need to worry about it financially when I have the factory extended warranty, about 4.5 years left in total.

    Yes, black smoke and diesel engines go hand-in-hand, but a diesel engine with a DPF shouldn't show any black smoke if the DPF is functioning correctly. That is the point of it.
