Version 1 Power Kit: Performance-Optimized Engine Software. This version of the Power Kit was first introduced on the 335i BMW Performance Edition model (announced in July, 2011). Available for all Model Year 135i and 335i vehicles. Also available for X6 vehicles produced up to 04/2010.
Version 2 Power Kit: Same engine performance software as Version 1, plus an Auxiliary Water Cooler and an Enhanced Radiator Fan to reduce the higher thermal stresses on the engine during extreme driving. |
I might be wrong, but I believe the engine software, along with the proper idrive software are done at port (i'm guessing halifax?). So if they got the idrive wrong, the odds are high that they got the engine flash wrong too.
