Hi,
If yours is a Prodrive car then the ecu will be different anyway, There are other options though, Powerengineering Phase1 (Chiptorque piggyback board) or GGR (similar) or a complete replacement ecu such as Gems, link or Apexi motec, autronic
I have an Apexi that would fit yours for sale, Almost new. Mapped by Simon, he is very good and local. Much better overall than when I was running Gems.
Speak to Pele about the PE Phase 1 as she has my old ecu which had this fitted.
Here is the link to my for sale ad.....
