In September 2001 the Newage Subaru Impreza was born.

Subaru had finally indirectly provided tuners with a standard ECU that was even more capable than a lot of aftermarket race ECU’s from that time and even from those available today.

There is very little in the Denso ECU’s programming that specialist tuners cannot access and as a result tuners have released the full capability of these fabulous ECU’s and the amazing Subaru Flat-four Boxer Engine with the potential to take your average Subaru Impreza way beyond standard running and onto power levels unheard of from 2.0L and 2.5L Turbo-Charged four cylinder engines.

Every aspect of Subaru engine running from the Ignition Timing and Turbo Boost to Air/Fuel Ratios and Rev/Speed Limiters can be altered by Remapping and Recalibrating the ECU.

This is achieved via a laptop connected to the EOBD port located just below the steering column. This is the electronic gateway into your ECU and subsequent power upgrades.

Standard Subaru ECU’s are programmed very conservatively by the manufacture, so much so there is a huge margin of safety built in and therefore quite a gap between how the car drives at manufacture to how it drives after professional remapping.

Subaru’s have built in bullet-proof reliability and the engines are sufficiently over engineered to take a lot more power than standard.
