Electronic tuning specialist, Superchips, has released a new performance boosting ECU remap for BMW's lively 135i Coupe / Convertible. The Buckingham-based tuner said that as measured at its in-house four wheel drive chassis dyno', the electronic upgrade boosts the 3.0-litre six cylinder twin turbocharged engine's peak power from a tested standard output of 315bhp to 360bhp. According to the company, the ECU remap also enhances the 135i's torque output, which rises from a measured 394Nm (290.6 lb-ft) to 456Nm (336.3 lb-ft) at 3,359 rpm. The maximum gain of 70Nm (51.6 lb-ft) is achieved at just 3,267 rpm. Even though the chiped-out 135i hasn't been clocked, Superchips claims that it is expected to better the standard car's 5.3 second 0-60 mph sprint time and when driven on a like for like basis, the car owners will experience no fuel consumption penalty as compared with the standard car. The ECU remap, which is suitable for both manual and automatic transmission variants of the BMW 135i produced from 2007 onwards, is available both directly from Superchips and its UK dealer network, with pricing set at
