    Throttle Response

    SDV6 on the odd occasion when flattening the throttle there is a definite lack of response.Mate of mine has fitted one of these to his Audi https://www.racechip.com/responsecon...88kw/index.php reckons its the best and cheapest mod he's done.Anyone fitted one to their D4?

    Get up and Go!

    My SDV6 has 155,000km on the clock and has plenty of GO once the Loud Pedal is pushed..........I personally would not chip my D4....but each to his or her own!

    Our TDV6 is more than adequate even towing the camper we have no issues getting around road trains or wobblies.

    Mate chipped is D3 and has had endless glitches so chucked it

    Hi Eddy,


    I've never heard of an SDV6 being slow off the mark once rolling but there are thousands of stories of them have really ****ty response at zero or very low speed.


    The reasons are inconclusive but I personally think it's the gearbox under certain circumstances or parameters. Some folks assume it's turbo lag but there are times from zero when you hit the Loud Peddle and it goes like a rocket with absolutely no delay. For me that would suggest gearbox.


    As I said, don't know the reason for sure but I'm not sure if more engine go would make any difference. However, Terry O has a V8 D4 and recons it goes like stink with no delay. I assume it has the same gearbox as the diesel .... so maybe there is more to it?

    The lack of response is inconsistent,sometimes there sometimes not.Like you say when it goes, it really flies off the mark.Could it be responding to driver input varying from senior mode to hoon?According to the link I put up,this device fits between the throttle pedal and the ECU and can be used in conjunction with a remapped ECU for max benefit, which is what my mate has done with his Audi.

    The transmission keeps learning and changing parameters all the time and the inconsistency you describe happens to us if we come back from a country trip where I have been using the throttle hard to overtake and we then settle down to puttering around town.

    I suggest you move to sport mode for a day or so and see if the same issue replicates

    You're a hundred precent correct and I regularly select 'Sport' to re-educate. However, I haven't found this absolute and I think my older 6 speed 3.0L was more responsive to this strategy than the new 8 speed ZF.


    I'm wondering if it's about how the ECU and gearbox communicate. Myself and a couple of other forum members discussed a while back, a very odd situation, when your engine just seems dead.


    I was on Fraser Island and the driving for once had been so easy, I turned everything off. I was in highway mode in high range (DSC was off). A couple of times .... and only a couple of times I applied pressure to throttle to get over a hump on a sand road .... and nothing happened. I mean nothing. I thought I'd had a failure. Unlike on the road, I also didn't get that big rush of power and torque when everything lit up. Even with more pressure ..... a very, very, very slow build of power occurred.


    Head scratching.

    Sport mode certainly overcomes the inconsistency.Question now is, does this box do the equivalent of sport mode at low speed or from stationary?

    These plugs appear to be catching on Sprint Booster For Range Rovers (2010 - 2013) - SBLR1022S But first I have to get an egr emulator.

    Those that have the problem with throttle response, have you had the transmission lag fix applied by LR service? It fixed it for me almost totally (only occurs rarely now when engine cold, and I brake, the suddenly take off, eg at roundabouts).
