The 034Motorsport 2.7T Stage 3 ECU Upgrade uses the latest generation of Bosch EV14 550cc Fuel Injectors, as well as the updated Hitachi 2.7T MAF Sensor to ensure adequate fueling and proper air metering. The ECU upgrade for this kit was developed in-house at 034Motorsport on our chassis dynamometer, and thoroughly tested on the dyno, street, and track to ensure optimal performance, safety, and reliability.
The 034Motorsport Stage 3 ECU Upgrade retains full electronic boost control via the stock N75 valve. The secondary oxygen sensors and EGT sensors can be coded out as desired.
