created the thread REVIEW & DYNO | Evolve Automotive Stage 2 Tune
I have always had such great interest in BMW Digital Motor Electronics (DME) tuning. As technology progressed, so has the complexity and intelligence of these DMEs. What has always amazed me were how there are an endless amount of maps all intertwined in a spiderweb of ways. What has always piqued my interest was that there are a few aftermarket tuners who have really honed the skill of calibrating these maps for better drivability, efficiency, and power. Many years ago, there was a time when there wasn’t really all that much to gain from tweaking these BMW DMEs. In some cases, you would be lucky to not lose power! With great innovations and forward strides in BMW tuning, expert tuners can now pull out very consistent and tangible power from the E9X M3 DME, the MSS60.
The E9X M3 is very responsive to a few simple bolt-ons, the most pertinent being the deletion of the primary cats. After installing my Evolve Automotive X-Pipe with 200cpsi cats, I knew I wanted to get a tune to not just turn off a pesky check engine light (CEL), but to further enhance the power and dynamics of the motor. With the drastic decrease in back-pressure from deleting the primary cats, I assumed that there was room for some proper VANOS tuning to further enhance and increase power and torque. Knowing that BMW designs their tunes to cater to a wild multitude of drivers, I figure that things may lean on the slightly conservative side. Being the power hungry individual that I am, I was hoping that slight tweaks in Air Fuel Ratio and Ignition Targets can help pull out a few ponies here and there.
Given my experience with Evolve Automotive when they helped me transform my E46 M3, I knew that by choosing them to work on my E90 M3 was going to be nothing short of a splendid experience. After getting their X-Pipe, I found it to be rather appropriate to get their tune as well.
Also knowing how intelligent the MSS60 DME is, I wasn’t expecting the most profound bump in power, especially relative to the drastic gains I felt with the Evolve Automotive X-Pipe. Despite that skeptical assumption, upon the first few hundred miles of driving, there was no doubt in mind a tangible difference in all regard. "
