Owners of cars from the BMW range, using the two-litre, turbocharged four-cylinder petrol engine can now enjoy significant gains in performance, thanks to the latest conversion from global ECU remap expert, Superchips. Previously we’ve seen remap conversions for the 20i and 28i, and now we complete the family with the 18i, 156PS variant.
The engine, fitted with Bosch management and found in the Z4 and X1, leaves the factory with a detuned 156PS. Because the power is artificially restricted, the conversion makes some astonishing figures. The Superchips remap adds a very impressive 121bhp at 6277rpm and 132Nm torque at 6070rpm.

Not only does the Superchips conversion demonstrate increases across the engine’s rev range, it also holds on to torque far longer and at a much higher level than the original engine. This means that the power curve also continues to climb past the original engine’s maximum level, which is reached at just 2500rpm. The remap is specifically designed to drive in a similar fashion to a big naturally aspirated engine – driveability and reliability are key. This means a significant improvement in performance, with acceleration greatly improved, but not at the expense of driving feel and throttle response.
The conversion is carried out by one of Superchips nationwide dealer network and typically takes around an hour. Customers can either wait at the dealer or drop off their car and return later to collect. The cost of the remap is £399 including VAT and labour. The conversion is covered by Superchips’ 12-month/30,000-mile warranty*.
