MOTIV PROTUNING – BMW S55

If you’re looking to get the most out of your BMW S55 car with stock, upgraded stock turbos, or even single turbo kits then a custom tune is for you. Let our BMW calibration experts work 1-on-1 with you to help customize your DME using the latest calibration tables from MHD or EcuTek. Every car is custom calibrated to be setup for you and your unique setup.

Our tuners have over two decades of combined experience and will directly remap hundreds of tables in your DME including comprehensive boost control, throttle behavior, ignition, cam timing, and many other tables that control how your engine performs.

Our team of BMW expert calibrators strive to provide a tune that is dialed in for your specific modifications, ambient conditions, fueling setup, as well as the condition of your motor. Off-the-Shelf (OTS) maps are designed to work with on a large number of vehicles often leaving efficiency and horsepower on the table. The custom tuning process allows us to dial in your tune specifically for your car, allowing us to achieve better drivability, more intuitive throttle mapping, reliable power/torque gains across the entire rev range, and not to mention improved gas/fuel economy.

Remote / E-Tuning is a process in which we will instruct you what specific parameters to log as well as how to go about performing the log. It is an iterative process and new map iterations will be sent after each set of logs we receive. We work hard with our customers until a satisfactory, smooth, and safe calibration is reached. Customers are encouraged to hit the dyno and gather dyno charts at their leisure. We support virtually any and all combinations of modifications for the S55 ranging from stock to all out single turbo builds. Let our team of tuners help dial your car in for your specific setup and help you transform it into what you know it should be.

To accommodate all different levels of customization and tuning we offer multiple types of tuning services. Please choose which one is best for you by reading about them below. Please do not hesitate to reach out to us if you have ANY questions about any of the following processes.

MHD FlexFuel

With the release of MHD’s FlexFuel we are offering a convenient package. The FlexFuel tuning is essentially two maps in one with a near infinite blending in between. One end of the map will be your local pump gas (90oct/91oct/93oct/94oct or the equivalent RON). The other part of the dual calibration will be the E85 portion. With a canbus enabled ECA like the one built into our Re|Flex sequential port controller https://www.motivmotorsport.com/products/reflex-advanced-i-o-integration?variant=39847834321080 the ethanol content % is transmitted over canbus to the DME. Based on these percentages the tune will interpolate in real time between the two sides of the file. When paired with the Re|Flex you can enjoy the most seamless and OEM integration with unparalleled safety.

REMOTE STREET TUNE

This option is perfect for the person who wants to be involved in the tuning process. Your feedback is just as important to us as the data we get from your performance logs in MHD or EcuTek. After a short discussion with your tuner about your vehicles setup, you will receive a base map to get a log of. Using your description of how the car felt, the .csv log file you send us, and your intended use of the car we will continuously update the file through multiple iterations. On average you will receive an updated tune file w/in approximately 24 hours of the logs being sent back to us. The typical number of revisions until completion ranges anywhere from 3 to 10 depending on many variables that we gauge based on the data your logs present to us. Some cars take more while others take less. The process moves at your own pace. The faster you get us logs the quicker we can get updates back to you.

REMOTE DYNO TUNE

Take the extra step towards a complete and flawless calibration. Our team of tuners will schedule a time with you to focus on your car and your car only. Whether you are local or anywhere in the world we are able to tune your car as though we were there sitting with you. In a 1.5-3hr dyno session we will fully calibrate your DME for your mods, engine health, and driving style. Focusing on creating efficient and power output we will use your logs and dyno plots to dial in your vehicle as precisely as possible.
