The “piggy back” system works by intercepting the signals from the vehicle’s factory stock sensors and channeling them through the custom pathway. The new product performs minor electronic modifications to the engine’s fueling and boost parameters in order to increase performance while maintaining the fuel economy and reliability of the unit.
The Unichip’s installation can be a DIY (Do It Yourself) operation, thanks to its plug and play design and “U-Connect” wiring loom. According to the company, the fitting or removing of such a device only takes minutes. The company also claims that the Unichip can’t be detected by automotive dealers during scheduled servicing sessions.
The Unichip Subaru Impreza 2.0 liter offers a 17 HP and 36 lb-ft (49 Nm) of torque premium, offering a total of 167 HP and 292 lb-ft of torque (396 Nm) for the driver to play with. The latter are delivered starting from 2,500 rpm.
The company says that the enhanced performance has not affected the fuel consumption of the engine, as real world testing has showed that the unit’s fuel economy has improved by 5 or 10 percent after the Unichip was installed.
The power enhancement can be purchased for 465 pounds sterling ($700) and is already available. The Unichip modifications cover a wide range of cars, from hatches to SUVs and performance vehicles.
