Map Notes for Lancer Ralliart

Supported Vehicles:

  •  USDM 2009-2015 Ralliart




Map Revision:

  • Stage1 v500
  • Stage2 v500




Required Accessport Firmware: 

  • AP3-MIT-002: 1.7.4.0-17852 or greater

COBB Custom ECU Features





Map Availability: Download from the COBB Tuning Ralliart 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, Stage2, and Stage3 gains vs Stock Power: 


Peak GainMax Gain
Stage1 93 

+8% HP / +7% TQ

+17% HP / +17% TQ

Stage2 93+14% HP / +12% TQ+22% HP / +20% TQ

Stock HP-217 / TQ-246 
Stage1 93 (98 RON) HP-234 / TQ-262 
Stage2 93 (98 RON) HP-248 / TQ-276 

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 Ralliart (93 octane fuel)



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: 18.5 PSI peak tapering down to 13.5 PSI by redline (+/-1.5 PSI)
  • Stage2
    • Boost Control Solenoid: COBB Electronic Boost Control Solenoid using supplied vacuum lines
    • Exhaust Requirements: Stock (aftermarket cat-back will not affect tune)
    • Intake Requirements: Stock airbox with stock air filter
    • Boost Targets: 21 PSI peak tapering down to 16 PSI by redline (+/-1.5 PSI)


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



Non Performance Maps

  • 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 Ralliart
    • 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 Ralliart 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.




Version#Notes
v500
  • Maps resaved for back end fixes
  • Maps have been updated to eliminate unnecessary DTC suppression.
v301
  • 2009/2010 USDM Ralliart - Adjustments made to idle timing to fix idle fluctuations.
v300
  • Maps updated to match latest performance map strategy.
v100
  • Original Calibration. Adjusted boost, fuel, ignition, camshaft phasing and base programming logic to improve driving quality and performance. Revised Closed Loop management for improved driving quality. Smoothed out boost related values, improved boost response at lower RPM. Altered intake camshaft phasing parameters in an effort to improve low and mid-range torque and boost response. Smoothed ignition advance mapping for low and mid RPM response.
