On the advice of EcuTek, I took a trip up north to see the amiable Andy Clark of AC Speedtech in Warrington to see what he could do. With a motor that could run more boost and fuelling than a standard lump and better aerobic capacity, I was keen to see what could be done with a little expert key-tapping and some bespoke work. While impressive enough when viewed in isolation, I was well aware that there was potentially a lot more power still to be extracted from my WRX, but getting at it would require a custom ECU solution, one free from the compromises inherent in any ‘one size fits all’ map.

It’s a well designed and carefully written piece of software that’s helped my car make a handy 340bhp, but it’s also an ‘off the peg’ map, and one applied to the ECU prior to fitting the new exhaust system. Keen Subaru fans will already be well aware of the 340R thanks to its (justifiable) popularity within the UK tuning fraternity, plus the fact that it makes use of EcuTek software. The car in question was far from standard, with a Milltek Sport exhaust system, some induction work courtesy of Pipercross, a fully forged engine with rock-solid internals, and the small matter of one of Subaru UK’s 340R maps. Its range of tuning suites keeps expanding, offering comprehensive packages for some of the most popular and commonly fettled cars in the world.ĮcuTek’s level of expertise and formidable reputation ensured that there was never anyone else in the frame when it came to re-mapping my Subaru WRX STi, a car that the North London concern has an impressive portfolio of options for.
