    Is the "Performance Chip" for the Rover V8 a Myth?

    Being a bit naive, for a while now I have kept my hopes up that an ECU upgrade (or chip) is available for the 4.0L V8, that actually does something other than rip you off.
    Am I deluding myself?
    Cheers,
    biggin

    P.S. I think I already know the answer to this question.

    I have an RRC with a D2 4l bottom end with a dp chip (I think that is what it says it is)

    It was on the car when I bought it. The preveous owner is a mechanic and his words were he was not as happy with it mainly due to the fact that he cannot adjust it.

    Makes no difference what the bottom end is, what injection is it running??

    Its running the 3.9 injection I believe, but I am not 100% sure. It has a different looking MAF to my 1988 model but it is still lucus?

    How do I tell?

    Does it have a distributor? If not its the later injection (good!) if it does a chip is a waste of money as your running a fuel only injection system. While you can make some (minimal) gains by tweaking the Air Fuel Ratios, unless you able too alter the ign timing(which your not using only a chip) your not going too gain much!

    Not so grasshopper!!

    There are a number of chip options for a 14CUX system. The best one is probably the Tornado.
    Have a look at the RPI website www.v8engines.com

    Search www.rangerovers.net

    Google is your friend with
    "tornado systems"
    "Mark Adams tornado"
    "14cux chip"

    Cheers

    there are a bucket load of chips for all variants of the 3.9.

    but most of them dont make much difference unless you also do some mechanical tweakery as well (reset timing as a minimum) to take advantage of the extra fuel they dump in.

    IMHO most of the chips that are available for the stock mechanically distributed 3.9 that work do so because they are remapping to suit the individual engines idiosyncrasies. When you start modding the engine then chipping is definately an advantage.
