581HP / 529LB-FT
Unitronic Stage 2 (MS109) Performance Software is precisely calibrated for use with 104 octane / 109 RON race fuel, engineered for a vehicle that has full hardware bolt-ons. It is the performance upgrade that will result in the most gains!
621 HP / 564LB-FT
Unitronic Stage 2 E85 Performance Software is precisely calibrated for use with E60-E85 fuel, engineered for a vehicle that has full hardware bolt-ons. It is the performance upgrade that will result in the most gains!
NOTE: E85 calibrations are not full flex fuel calibrations, therefore, when using an E85 ECU calibration, the engine is only designed to operate on E85 blends from E60-E85.
Using an E85 calibration with pump gasoline or race gas may result in engine damage.
Unitronic strongly recommends the use of an Ethanol Content Analyzer, to ensure Ethanol content levels are within the permissible range. When switching between gasoline to ethanol, please use Unitronic’s fuel conversion guide here. Unitronic recommends using NGK R7437-9 spark plug gapped to 0.024” +/-0.002” (0.6mm +/0 0.05mm) with Stage 1+ E85 and Stage 2 ECU calibrations, with a replacement interval of 10,000-15,000 miles (16,000-24,000 km).
Unitronic Stage 2 TCU Performance Software is required to run Stage 2 ECU tune.
Performance Software for your ECU Box Code is subject to availability.
2019+ models may require to have the hood opened during the flashing process.
Flashed directly through the (OBDII) Diagnostic port of your vehicle (10-15 minutes).

Engineered with Strict Industry Standards With over 10 years of experience with Bosch and Siemens engine management systems and calibrations, Unitronic is able to utilize its expertise, industry leading tools and equipment to ensure an optimal calibration; delivering maximum performance, while maintaining complete OEM-like reliability and drivability.
Extensively Tested Under Various Driving Conditions Development begins using Unitronic’s in-house Maha Chassis dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Beta calibrations are then tested in street and track scenarios, using multiple cars under various driving conditions. This engine calibration strategy ensures Unitronic Performance Software delivers maximum performance, OEM-like drivability and reliability anywhere in the world. Unitronic Performance Software is only released to its Clients once development is thoroughly completed in accordance to Unitronic’s strict standards.
Factory Safety Limiters Retained OEM “fail safes” are retained within the ECU calibration. Close monitoring of all operation parameters ensures that engine operation stays within factory components limits, resulting in reliability.
Optimized Responsiveness, Smoothness, Drivability, and Comfort Unitronic’s ECU calibrations are engineered to improve engine response and reduce low-end lag. Unitronic’s Performance Software has gained worldwide recognition and is well known for its broad powerband, with smooth power delivery, maximizing responsiveness and “area under the curve”, under normal and hard acceleration.
Optimized Maximum Output Unitronic’s ECU Calibrators deliver the maximum power output while staying within the operational limits of the factory engine and drivetrain components. Specifically, this results in the highest engine performance without sacrificing the reliability of the engine, turbocharger, or other engine and drivetrain components.
Speed Governor Removed Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)
Left Foot Braking (LFB) Enabled LFB allows users to apply load on the engine using their left foot on the brake, to build boost when the edge is needed at the race track.
Spark-based "Motorsports" Style Rev-limiter Enabled The traditional rev limiter will de-load of the engine as engine speed reaches maximum RPM. Unitronic has enabled the spark-based rev-limiter, to avoid the de-loading, allowing power all the way to the rev-limiter.
Exhaust Crackle/Overrun Enabled Unitronic has recalibrated the Exhaust Crackles/Overrun/Pops & Bangs when in Dynamic/Sport Mode to be more aggressive and louder.
Exhaust Flaps Always Open in Dynamic/Sport Mode In factory form, both Exhaust Flaps are not open when in Dynamic/Sport Mode. Unitronic enables both Exhaust Flaps to be open at all times, when in Dynamic/Sport Mode, for maximum performance and sound.
Full Staged Software Suite Includes all Stage 2 tune variants and all lower software stages as well.
