Unitronic® Stage 2 Performance Software and Hardware is now available for the MK7 Jetta®, Golf® and Golf Sportwagen®, equipped with the 1.4TSI EA211 Gen2 DGX and DJX engine.* With the help of Unitronic's all new 1.4TSI Gen2 Downpipe, power outputs are increased by up to +42HP / +90LB-FT** with Unitronic Stage 2 93octane / 98ron Performance Software for a maximum of 189HP / 274LB-FT. Unitronic is also proud to announce this software upgrade is entirely compatible with its UniCONNECT+ cable.


AVAILABLE UNITRONIC SOFTWARE

Unitronic MK7 1.4 Jetta Dyno Stage 2


Building upon on our popular Stage 1 / 1+ calibrations, Unitronic Engineers set out to raise the performance bar with our all-new 3" Catted Downpipe specifically designed to reduce backpressure and improve turbocharger efficiency for the 1.4TSI EA211 Gen2 engine. Research and development of Unitronic’s Performance Software and Hardware is carried out with dyno, track, and road testing, while closely monitoring running conditions through high-speed data logging tools and equipment to ensure maximum performance is achieved, without compromising OEM-like reliability and drivability.

After extensive development time and countless hours of flash protocol testing, a multitude of empirical data is collected from around the world. Once a thorough analysis is completed, Unitronic calibrators develop the Performance Software which is fully optimized for maximum performance while staying within the constraints of the OEM hardware to ensure reliability and drivability are maintained. This results in Stage 2 (87, 91 and 93 octane / 91, 95 and 98 RON) ECU calibrations fully supported by Unitronic's UniCONNECT+ cable.


UNITRONIC 1.4TSI GEN2 DOWNPIPE


Unitronic-MK7-1.4-gen2-dp


The Unitronic 1.4TSI Gen2 Downpipe (UH035-EXA) is constructed of 3" T304 stainless steel mandrel bent tubing, T316 stainless steel flanges, a corrugated stainless steel flex section, and TIG welded fabrication, this downpipe is built to withstand the test of time, while performing to the maximum. All Unitronic downpipes come equipped with a 200-cell high flow metallic catalytic converter and all transitions are flow-matched to allow for maximum performance and airflow.

This Downpipe also features an easy-to-use v-band fastening system to ensure quick and effortless installation with precise fitment. All Unitronic Exhaust Systems come equipped with a brushed matte finish for an elegant appearance that will last a lifetime while being backed by our Limited Lifetime Warranty.

SOFTWARE FEATURES


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.

Ignition Timing Precisely Calibrated for Higher Octane Fuel

Engine calibration optimized to take advantage of higher fuel quality to extract maximum energy from the combustion. Therefore, when using a higher octane fuel, more power and better fuel efficiency will be achieved.

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.

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.

Power Delivery Perfectly Optimized Throughout the Power Band

Aligned with the OEM strategy, the calibration is designed to offer a large flat torque plateau to provide a smooth and linear power band. Maximum torque output is achieved sooner and maintained longer which creates a broader torque plateau and greater area under the curve. This results in an improved acceleration and optimal engine operation.

Speed Governor Removed

Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)

Improved Fuel Efficiency

Optimized timing and injection in cruising condition allows for an improved fuel efficiency, under normalized driving conditions.

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.

Hi John
Can you tell me about UniTronic Stage 1 tune for a stock factory Golf 7.5 1.4TSI engine.
Can I buy it with the USB obd cable & flash at home?
How is the reliability. 95RON fuel.

I've heard the factory clutch can't handle it but some other people say it can. what is the real answer?
