BMW F8X M2C/M3/M4 Engine Tune (2015-2020)

BMW F8X M2C/M3/M4 Performance Tune

FAQ

How do I get my BMW F8X M2C/M3/M4 Tune?

Getting started, there are many ways to skin that cat.

1. We can set up your BMW M3 Tune through Bootmod3 or MHD.
2. If you do not have a need for the extra features that BM3/MHD enable, we can supply a single-vin Femto license for flashing.

Tuning is also of course available full-service at our headquarters in Dallas, Texas. No additional tooling is required.

What do I need to tune my BMW F8X M2C/M3/M4?

We are capable of tuning for whatever modifications you may have.  Some clients are bone stock and looking to make the most of race gas.  Other clients have built engines, upgraded hybrid turbos, upgraded single turbos with mac solenoids, etc. Ultimately, Cedar Performance will sort out the calibration. We work inside or outside of all tuning platforms, provided they do not limit us from editing the tables we desire.

Will my tune have Map Switching?

Provided you have a Bootmod3/MHD License and your ROM is supported, Cedar Performance is happy to calibrate multiple maps for use with the on-the-fly map switching logic.  Generally speaking, Map Switching is used for things such as:

• High/Low Boost Settings
• Antilag/Burble Adjustments
• Flex Fuel Enabled/Disabled
• Octane Adjustments (Pump vs Race Gas, E85 vs C85)

Will my tune support Flex Fuel?

If the vehicle is equipped with a Flex Fuel Sensor and Analyzer such as the one offered by the Bootmod3 Team, we can utilize this hardware in combination with Bootmod3 or MHD’s Custom Rom to develop true and proper Flex Fuel Control as seen in the graphic below. These flex fuel calibrations are full and complete torque scaling calibrations. Our calibrations have 100% proper utilization of fuel, ignition, and torque factoring tables to give consistent yet maximized performance for all contents of ethanol.
