TTFS SMG Software

The TTFS SMG Software tune is a must for all E46 M3 SMG owners. Most of our customers wonder why BMW did not have this from the factory for all E46 M3 SMG cars.  The tune is kept under the same parameters as the BMW CSL, but it is not the same as the OEM BMW CSL.  Customers who have purchased both tunes are still very pleased with the result, as our famous SMG tune really works out the sloppiness of the transmission electronics.
