my cousin has an 06 m3 and he has these on his car. i dont know if they are the same brand but they definetly work. nothing astounding, but they do do what they say
Anything new on these? Apparently some magazine tested them, and they helped, but with a magazine, you can never tell if the test was influenced by advertising dollars or not.
haltech ev112, motronic m600 are the best ems out there and the motronic can control the variable camshafts.
I think you meant Motec M600. Motronic is made by Bosch. The Motronic system is used by the GA cars and would be a real pain to use compared to the other two systems you listed as I don't believe it is sold as a stand-alone. It is the factory system for most Porsche cars.
