APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.2 TSI engine. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.
The ECU’s Simos 10 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.
APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, lambda and more to produce higher output!
APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world.
The APR ECU upgrade is one of the best value modifications for the 1.2T engine. The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 168 ft-lbs of torque and 133 horsepower with 98 RON octane fuel. Large gains were seen throughout the power band, including an additional 37 ft-lbs of torque and 26 horsepower. Even higher figures were achieved using race fuel!
Stock - 95 RON As Reported by VAG | Stock - 98 RON As Measured by APR | 95 RON | 98 RON | 108 RON | |
---|---|---|---|---|---|
- APR recommends and tuned with Sunoco GT 260 for 100 RON mode and Sunoco GT 260 Plus for 104 RON mode. Never use lower octane than specified by the mode. | |||||
- Max increases are based on APR's actual measured stock values and not those reported by VW. | |||||
- Reported wheel figures measured on APR Australia's in house Dynapack Dynamometer with an Australian Spec Polo DSG (105 HP), using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. | |||||
