It has a been over a year since I have had this tune and it has been awesome. I have used my buddies cars that all have Gintani etc and the ESS just seems clean and to the point. Really wakes up my M3 which I am running with full catless X pipes. I bought this tune as I still plan on purchasing a supercharger in the future for this car and I wanted to get a gauge for the company and service. The service is top notch and you can use the tuner dongle to read codes on your OBD port. Only reason I give it 4 stars is that I wanted the burble tune and AJ noted in a email that he would be able to provide a burble tune. I got several files that put my car in limp mode as they were just tests and the issue never resolved. A year later and living in California I outgrew the idea of burbles but the issue was never resolved. All in all great company and tune!

I purchased the software from ess with a view to next year upgrading to the supercharger system.I'm please to say the custom map they did for my car has far exceeded my expectations and is absolutely fantastic.Very pleased I decided to go with these guys and really looking forward to working with them more next year with one of their supercharges set ups. I would highly recommend these guys and already have to a few fellow BMW owners over here in the U.K. Thank you ESS
I researched almost every tune that you could run on the E9x chassis. Having come from a S2000, I was almost expecting a stand-alone type EMS for the E9x but was sadly mistaken. However, as for the current tuning market; ESS is as good as it gets. Almost EVERY other company charges you for an additional tune. Since I live in CA, and smog is an issue; I was looking to go for a route that would afford me the opportunity to run a test-pipe tune without having to pay extra (and that extra runs $200-500+!). ESS was the only company would wouldn't charge me extra for a test pipe tune in the future. Their customer service and tuning emails all came within 24 hours. Something I didn't get from 90% of the other companies. Not only that, the questions about my tune were answered just as quickly. A lot of people won't take into account the customer service side of things until they need it. Then, when something happens and you need support is when you realize that mistake. You won't need to worry about that with ESS. My first experience with them and I couldn't be happier. As for the tune; in all my research, ESS was at the top again. MotoIQ's Billy Johnson did a tune and posted the dyno results and they speak for themselves. My car feels MUCH better driving in the lower end of the power band. The throttle response is much better. The only downside is the slight dip in gas mileage (about 1-2 mpg difference for the freeway); but having come from multiple tunes in my S2000, it's nothing surprising (especially since they warn you about the first 100 miles and the ECU learning the car with a new map). I'd recommend ESS to anyone and I will definitely be using more of their products in the future. Thanks again ESS!
