Product Description

Essentially all development for S85 powered M5 and M6 cars stopped in 2009. Being that we had numerous local customers with S85 powered vehicles, we decided to open up the books and start from scratch on our in house S85 development. We have been developing mapping for the MSS65 in the E9X M3 for years. From that, we learned many strategies that directly correlate to tuning the S85. Development was done on numerous different vehicles with different ranges of modifications on our in house Mustang Dynamometer. Unlike most that offer S85 tuning, we started from scratch rather than simply buying files from European software engineers. In the tuning market, many shops buy modified files from European developers and call them their own. While gains are to be had with canned flashes on the market, some may not optimize all the available tables on a dyno like we have. Any car that is dyno tuned and tested can make higher gains then a canned flash. One can easily tell who is developing and who is buying pre-tuned maps and selling them as their own by looking at who has an in house chassis dyno for development. At BrenTuning, we always strive to innovate rather than copy. We are at the forefront for development of many different platforms — the S85 is no different.

We were able to gain 40WHP and 24 WTQ with software only on an otherwise completely stock 2006 BMW E63 M6 including OEM charcoal filters installed. The tuning changes include a flash to the ECU (engine control unit) as well as TCU (transmission control unit) including software changes for the SMG transmission with every tune we provide. The result is smooth gains throughout the entire rev range along with quicker shifting and an available extended rev limiter.

This software can also be flashed at home using our BrenTuning MPF OBD-II flashing unit which includes up to 3 tuned maps and 1 original. We can of course also adjust the tune based on modifications such as headers, exhaust, Alpha N, race fuel, E85 mixes etc.  Custom maps can be made in reference to rev limit, vmax, throttle response, or driving preference.

All of the gains that we have been quoted are on 93 Octane, if you plan on using 91 Octane, plan on making 10WHP less than a comparable 93 Octane car.

This product is available in all markets US and abroad, we offer in house dyno tuning which can be scheduled directly via the contact us button on our website. For our handheld device, a windows based computer is recommended. For optimum performance, an ECU pull to reset is requested (instructions available).

E85 Flex Fuel Tuning kit is also available for these vehicles. Simple under 1 hour install will allow you to receive the benefits of race gas for $2/gallon. Huge gains over pump fuel! Talk to your rep today about going flex!

A must have is our high flow drop-in filters which were dyno tested to 12WHP gains. Found HERE

  • “ Professional, knowledgeable and friendly. The BrenTuning team delivered excellent work and answered all of my questions. Their E-Tune service was a great experience and I would do it again. ”

  • “ I highly recommend Bren Tuning. I've gone to see them twice with my 15' STI, first time after getting the access port and installing an intake and last week for GS downpipe, N1 cat back and of course another tune. Couldn't be happier with the results, car runs and sounds even better that I expected. ”

  • “ Had my 2010 335xi serviced here and I have nothing but good things to say about these guys. I had a lot of work done at once and it all came out perfect. Definitely recommend and you are guaranteed to be pleased with the results! ”

  • “ Just finished getting a e-tune on my 15 wrx and its amazing! Car runs so smooth and has so much power! I highly recommend them for anything you need for your car. I will be taking the 3 hour trip to get more work done. Customer service was great and speedy! ”

  • “ I've been working with Bren for over a year now on my 2015 STi. It's not often I find a shop that shares my perspective when it comes to my car. Down to earth, "REAL' car-guys. They treat my car as if it were their own, and do their best to exceed my expectations every time. I also use them for maintenance on my car. Its where I prefer to bring my car, because I know nothing will be overlooked. And when track days come around , they'll be there too, to help and advise me every step of the way. I cant ask for anything more than that. ”

  • “ Bren seriously took his time with my tune and it was absolutely amazing. Really worked hard to get it right and when I saw that dyno sheet I almost wanted to cry from joy, power curves were amazing and he ended up getting me perfectly to 337hp 337tq. I couldn't be more happy with numbers like that. Not only was the tune amazing, but the customer service. I had a 330 spot on a Friday, ran into some trouble getting there and wasn't able to arrive until 45 minutes after my appointment. I simply called them, and was told exactly this "hey man no worries we understand, get here whenever you can and we'll make sure we take care of you tonight." To me... That says it all about Bren right there. Excellent work, you've got a lifetime customer here. ”

  • “ Had an install and protune done with Bren and the team on my 2015 WRX. Car put out absolutely stunning results! Bren really took time and patience getting the tune right. After the dyno tune he sat with me for a ride along to make sure everything was to my liking. Great team, very friendly, down to earth and professional! ”

    Vahe Keshishian May 12, 2017
  • “ Got my 2015 Wrx e-tuned by Brentuning and could not have been any better. All my questions and concerns were answered in a timely fashion along with the tuning process itself. Car is now so much more drivable with the rev hang removed, pulls much smoother, and pulls way harder all the way to redline. ”

    Perry Alpert May 12, 2017
  • “ Hands Down...The BEST Customer Service Ever. I have a Stage 2+ 2012 STi and worked with BrenTuning to have a Protune added. The car feels completely different. There is significantly less delay in response time. The boost holds much better and is a much smoother pull. I can also feel a significant gain in tongue. Their response time was incredible though. Communication was done through email and the turn around time was instantaneous, literally felt like texting. I would highly recommend BrenTuning for great work and outstanding customer service. ”
