1995 BMW E31 850csi Performance chip set +20 HP 18 TRQ

  • Hi,


    Saw this on ebay, anyone know anything about them?


    They look like similar to the Dinan upgrade but obviously aren't.


    Also does anyone have any experience (good or bad) of any of the other
    so-called chip upgrades that can be found on the net?

    '96 BMW 850CSi
    '11 MV Agusta Brutale 1090rr
    '89 Ducati Indiana 750
    '83 Suzuki GR650


  • Wokke chips seem to be regarded as the very best around. Pity he doesn't do any for the 850Ci (I mean M73 engine)


    Then again, I'm still getting used to having around 326 HP, I need to practice some more before I start adding to that :)

  • Take note that there is a programming change in the CSi ECU's in 1995 so pre 95 and post 95 chips are different and not interchangeable.
    You will need to know your car build date as MOST chips do not work in post 1995 cars. There is also a difference in the chips between Euro and US cars because of the DME communications with the EML.
    For a certain 1995 CSi upgrade then Superchips is the ones I chose and they worked. another VERY big chip tuner in the UK chipped my DME's and burnt them out! Cost £1200+
    I am not prepared to say who they are as they made good on the costs.
