In another thread I inquired about the availability of aftermarket ECUs that would properly interface with a 2008 VW R32 and the general consensus was that this was unlikely. While searching for something unrelated I happen to come across a UK ECU system supplier by the name of Syvecs that does offer PnP systems for a variety of popular late model Euro models. While most people visiting these forums may not be interested in a relatively expensive aftermarket engine management system, these PnP systems may be useful for folks looking to go from an NA engine to a forced induction (FI) engine while retaining all of the complex electronics on modern vehicles with a manual or DSG trans. The Syvecs S7Plus appears to be a relatively user friendly fully configurable ECU system viable for street or track use.
I have no association with Syvecs but may actually purchase one of their systems to try.
