    ***All NON-USDM vehicles contain Stage 0 maps only***


Current Map Revision:

  • Anti-Theft v500
  • Stage0 v500
  • Stage1 v500

COBB Custom ECU Features





Map Availability: Download from the COBB Tuning Evolution X OTS Map Database 




 Hardware Requirements:


Calibrations can be used on vehicles that maintain stock turbochargers and a stock fuel system. No 3rd party intake system is confirmed to work with these calibrations. Specifics noted below, per map file.

All calibrations will require the use of an upgraded fuel pump relay for safe operation. Details ARTICLE: Evo X Fuel Pump Relay Replacement



  • 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 "93" are for use with 93 and 94 octane/98 RON fuel or better.
    • Maps designated with "91" are for use with 91 and 92 octane/95 RON fuel or better.
    • Maps designated with "ACN91" are for use with 91 octane fuel found in Arizona, California, and Nevada or better. And additionally for those in Canada, for use with 94 octane Fuel at a minimum.


    These maps are designed for E10 fuel (fuel with 10% ethanol content). For those who only have access to E0 fuel (fuel with 0% ethanol) it is recommended to use the "91" and "ACN91" octane versions of the maps and datalog the car to ensure your fuel is performing to the necessary level. This is especially important for those using Canadian 94 octane E0 fuel. 





Typical Stage1 gains vs Stock Power: 


Peak GainMax Gain
Stage1 93 

+13% HP / +10% TQ

+13% HP / +14% TQ

Stock HP TQ 
Stage1 93 (98 RON) HP TQ

Peak Gains are measured as the absolute maximum value between the highest points of two plots. 
Max. Gains are measured as the average maximum value between the highest and lowest point of two plots. 

Results may vary. Power as tested on 2013 Evolution X MR (93 octane fuel). Generally speaking, MR models will make less power than GSR models due to drivetrain losses (transmission differences).











Map Version Notes:

Note: All performance maps are equipped with 2-way map switching. Performance maps are by default loaded into the first map slot and an economy map is loaded in the second map slot. 




Stage 1 Maps (Map0 – Performance, Map1 – Economy)

  • Stage 1
    • Boost Control Solenoid: Stock with stock restrictor pills
    • Exhaust Requirements: Stock (aftermarket cat-back will not affect tune)
    • Intake Requirements: Stock airbox with stock air filter
    • Boost Targets: 23.5 PSI peak tapering down to 17 PSI by the 7000 RPM redline (+/-1.5 PSI)
  • Stage1+CHFF
    • Boost Control Solenoid: Stock with stock restrictor pills
    • Exhaust Requirements: Stock (aftermarket cat-back will not affect tune)
    • Intake Requirements: Stock airbox with COBB high flow filter (panel filter)
    • Boost Targets: 23.5 PSI peak tapering down to 17 PSI by the 7000 RPM redline (+/-1.5 PSI)
  • Stage1+SF
    • Boost Control Solenoid: Stock with stock restrictor pills
    • Exhaust Requirements: Stock (aftermarket cat-back will not affect tune)
    • Intake Requirements: COBB SF Intake
    • Boost Targets: 23.5 PSI peak tapering down to 17 PSI by the 7000 RPM redline (+/-1.5 PSI)


Notes: The additions of any other hardware may cause the vehicle to perform poorly 



Non Performance Maps

  • Valet Mode
    • Rev limiter set to 4600 RPM. Boost set to wastegate spring pressure.
  • Anti-Theft Mode
    • This map will not allow the vehicle to start.
  • Economy Mode
    • Bundled with performance map and found in secondary map slot (Map1)
  • Stage0
    • Intended for an otherwise stock Evolution X
    • Stock ignition, timing, and boost control



Closing Warnings and Precautions:

  • Use of inappropriate calibration/modification combinations will promote engine damage
  • Seek the help of a professional COBB Protuner should your Evolution X fall outside of OTS map requirements.
  • Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.
