The BMW S54 engine (found in E46 M3 cars from 2001-2006) is an excellent powerplant and great for engine swaps as well as forced induction applications.  The ACE Performance Syvecs kit allows for you to seamlessly install and control a robust engine management solution.  

ACE utilizes a Syvecs S6 engine control system and a re-pined BMW S54 factory engine harness as the base of this kit and has developed a number of solutions to ensure that all systems will operate as if being controlled by the factory engine management.  The Syvecs S6 unit will come with a ACE supplied base calibration for this system and support your local tuning shop with the final dyno calibration (performance tuning).    

The ACE BMW S54 engine management kit allows for easy race dash installation as data can be sent through CANbus.
