Owners looking to improve the carвЂ™s performance for fast road driving look to stiffen the suspension and reduce the roll and flex from the chassis. Suspension & HandlingДЇrom the factory the Impreza is designed to cater for a variety of applications from town work to fast road. This will give you a cost-effective braking improvement.

The STi setup works well from the factory but can also be improved with a good quality set of Brembo high carbon rotors with the correct choice of upgrade pad. Those with more budget can consider fitting a new set of Alcons. The most effective upgrade is to fit a set of Brembo brakes from an STi. You can upgrade pads, discs and fit braided lines but the problem is the caliper and the size of the disc. The WRX model is notorious for suffering with poor brakes. The engine and powertrain have been developed and significantly improved over the years and there are a host of performance bolt-ons and tuning options to further improve this already awesome carвЂ™s potential. The Impreza was one of the first accessible cars to offer supercar rivalling performance. Subaru won their first World Rally Championship in 1995 at the hands of rallying legend Colin McRae, which cemented the ImprezaвЂ™s appeal.

Like Full Throttle Shifting, the ideal RPM is calculated automatically to match the engine speed with the next lower gear.First announced back in 1992, the Subaru Impreza quickly gained a cult following thanks to its real-world performance and success at the highest levels of World Rally. Downshift Throttle Control: on DBW cars the throttle can be controlled when downshifting (aka 'throttle-kick').That meets the same objective as anti-lag but puts usually less stress on the engine. The ideal RPM for up shifting is calculated automatically and the ECU limits it to this value to avoid a driveline shock when engaging the clutch again. Full Throttle Shifting: this function allows to up-shift while keeping the throttle fully open to avoid turbo lag.These parameters will lead to more or less boost and so more or less torque off the line. The ideal engine speed (for example 4000 RPM), boost level, fueling and ignition timing retard are tunable. Just keep the throttle fully open and release the clutch when you're ready to launch! Launch Control: this function allows very quick launches by making boost while the car is standing still.On DBW cars, the throttle is fully tunable when ALS is running. To burn fuel into the exhaust manifold to spin up the turbo and make boost. When anti-lag is activated the injection time is raised combined with a lot of ignition timing retard Where it is normally impossible, mainly when shifting or braking. Anti-Lag System (ALS): the goal of the ALS is to reduce turbo lag by spinning the turbo and producing boost in situations.

This function can be completly customized (minimal throttle opening, boost threshold).ДЄ VE table (Volumetric Efficiency) define the cylinders filling depending on RPM and MAP/BAP ratio (absolute pressure divided by barometric pressure, to take into account altitude changes).ДЇor a perfect management an air temperature sensor must be installed on the intake after the intercooler if the car doesn't have one already. In this mode the boost solenoid is kept open at its maximum while the boost rises. This exclusive function allow to attain the boost target as fast as possible, including while shifting.

Spool-up mode: the boost control logic of 'old' cars (1998-2000) is known to have a poor boost control system, usually with slow spool-up.

With the advantage of keeping all safety features in case of a sensor failure. It is an exclusive ECULABS function that make any additional boost controller obsolete, It is then possible to get maximal turbo performanceДЇor all gears, without compromise, or to manage a different boost level from one gear to another (for example lower the boost at high RPM in fifth or sixth with a standard intercooler

With GBBC each gear have its own full control depending on RPM (not only a correction factor). The turbo doesn't react exactly the same depending on selected gear (less boost in first gear, sometimes too much in fifth or sixth). All running phases of the engine (starting, cruising, full load)ДЄs well as the transitions (tip-in) affecting the driving quality are managed perfectly.

Big injectors: all parameters needed for a perfect management of big injectors are available.
