  • USDM 2016-2018 Focus RS



All Focus RS

Map Revision:

  • Stage1 91 v305  
  • Stage1 93 v305
  • Stage2 91 v305
  • Stage2 93 v305
  • Stage2+ 91 v305
  • Stage2+ 93 v305


*** You may see our map descriptions include notes, such as Stage 5 or Stage 6.1. This relates to European Emissions Standards.



Required Accessport AP-FOR-004 Firmware:

  • V3: 1.7.3.0-17635 or greater



Map Availability: Download from the COBB Tuning Focus RS OTS Map Database 


Fuel Requirements: 
Each map lists the minimum required octane. A higher octane fuel can be used safely on a map designed for lower octane. DO NOT use maps designed for higher octane with lower octane fuels. Top Tier gasoline should be used where available. 

  • Maps designated with "91" are for use with 91 and 92 octane fuel or better. It is also recommended to use a 91 map when running 94 with 0% ethanol.
  • Maps designated with "93" are for use with 93 and 94 octane fuel or better. 

  • Maps designated with "95" are for use with 95 RON fuel or better.
  • Maps designated with "98" are for use with 98 RON fuel or better.

Calibration Strategy Information 
See our Octane Adjust Ratio technical article for additional information regarding some of the strategies we utilize in these calibrations! 



Feature Descriptions: 


No hassle launch control

  • Enabled on all v110 and up OTS calibrations, this features allows for easy use of the launch control system. Once a v110 or newer calibration file is flashed onto the vehicle, the process of getting into launch mode is simply having the clutch pedal and accelerator pedal depressed fully. The vehicle should quickly raise engine speed to the determined RPM set in the calibration file. These values can be found under the Map Notes heading for each OTS map above. 

Flat foot shifting

  • Enabled on all v110 and up OTS calibrations, this features allows the accelerator pedal to stay fully depressed while shifting the vehicle. The use of the clutch pedal will still be necessary, but keeping the accelerator pedal fully depressed between shifts allows for the turbo to stay spooled between gears. The RPM target value for the flat foot shifting feature can be found under the Map Notes heading fore each OTS map above. 

5 Way map switching

  • This feature enables users to switch between map slots on the fly. Once a v110 or newer calibration file is flashed onto the vehicle, the end user can use the factory cruise control system to switch between different maps. The number of available maps is adjustable with Accesstuner software. Custom tuned calibrations can contain up to 5 switchable maps. v110+ maps included with your Accessport or downloaded from the COBB Tuning website contain three maps that are switchable in real-time. Map 0 is the high performance map, map 1 is OEM performance setting, and map 2 is economy mode.




Closing Warnings and Precautions: 

  • Use of inappropriate calibration/modification combinations will promote engine damage.
  • COBB OTS mapping is NOT designed to be used with upgraded aftermarket boost actuators or solenoids. Doing so may result in much higher than desired boost and potential engine damage. Seek the help of a COBB Accesstuner Professional should your vehicle fall outside of OTS configurations.
  • Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.
  • WARNING: Launch Control, and Flat Foot Shifting are abusive to the engine, clutch, transmission, axles, and differential. The user accepts all risks and responsibilities when using these features.
