Unitronic strongly urges its Stage 3 ECU Performance Software calibrations to be utilized together with a built engine/fortified bottom end. Stage 3 ECU Calibrations for the TTE700 are available in a "torque-limited" and "unlimited" formats, with Ethanol fuel. Maximum or "unlimited" torque ECU calibrations are meant to be used with built engines and require an Iroz Motorsports Single Brushless LPFP and Unitronic 4 bar MAP sensors.* Stage 3 TTE700 93oct/98ron ECU calibrations are also available with the LPFP and MAP sensor upgrades. Power figures displayed for Stage 3 TTE700 with E85 fuel are not representative of the maximum torque ECU calibrations. Stage 3 TTE700 "Torque-limited" ECU calibrations for Ethanol fuel are for use with the stock LPFP and MAP sensors. Stock LPFP's are not all created equally and output may vary; Ethanol content levels should remain ~E70 with the stock LPFP, air quality dependent.
Unitronic Stage 3 TCU Performance Software is required to run Stage 3 ECU tune.
*Unitronic 4 bar TMAP sensors are only available for customers who own or have purchased together with Stage 3 ECU Performance Software.
Performance Software for your ECU Box Code is subject to availability.
2019+ models may require to have the hood opened during the flashing process.
Engineered with Strict Industry Standards
With over 20 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.
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 3 tune variants and all lower software stages as well.
