BMW’s range of 3.0 D powered cars enhanced by Superchips ECU remap


BMW’s 245 bhp 3.0-litre, six-cylinder, direct injection common rail power plant is arguably the most refined and potent mainstream diesel engine on sale today. However, given the nature of the brand, it’s no surprise that there is strong demand from BMW owners seeking to tailor their car’s features to their own individual driving preferences.

Hence why Buckingham based automotive electronics experts Superchips are pleased to announce the launch of a new ECU remap designed to increase the potency of the 2993cc BMW diesel engine, as found in the following popular applications:

  • 3 – series (E90 / 1 / 2 / 3)
  • 5 – series (F07)
  • 7 – series (F01)
  • GT (F10)
  • X5 (E70)
  • X6 (E71 / 2)

Diligent analysis of the BMW’s Bosch EDC17 ECU enabled Superchips technicians to pinpoint potential areas of improvement to both the performance and efficiency of the 3.0 D engine, involving the careful optimisation of fuelling and turbo boost settings within the revised Superchips remap. These changes have then been rigorously validated through a combination of real world road testing and extensive chassis dyno assessment.

The performance gains from the Superchips ECU remap are significant. Power increases by 44 bhp at 4183 rpm, resulting in an impressive maximum output of 313 bhp (up from a measured 264 bhp as standard.) Importantly, these power improvements are realised throughout the rev range, from 1500 rpm all the way to the rev limiter at 4500 rpm. For safety reasons the 155 mph rev limiter is left unaltered.

However, the Superchips BMW 3.0 D remap also provides a noticeable increase in torque output, resulting in a maximum gain of 90 Nm of torque at just 2222 rpm, taking the peak figures from a measured 549 Nm to 627 Nm (457 lb.ft.)

Behind the wheel the Superchips remapped BMW 3.0 D feels much more potent. Throttle response is sharper, the engine feels keener, more urgent and more willing, pulling harder throughout the rev range. Meanwhile, the additional torque available from the Superchips ECU remap enables relaxed, stress-free overtaking, cruising and towing.

And thanks to careful work of Superchips ECU experts, these performance improvements have little or no impact on the BMW 3.0 D engine’s renowned frugality. In practice the Superchips ECU remap delivers extra fuel efficiency thanks to a combination of performance optimisation and the removal of factory compromises designed to cater for service neglect or low grade fuel.

Superchips is confident that if a remapped version of any BMW 3.0 D model is driven in a ‘like for like’ manner against the standard version, owners will experience noticeable fuel economy improvements due to the additional low rev torque delivered by the Superchips upgrade.

Installation of the Superchips ECU remap for BMW 3.0 D models entails customers visiting one of approximately 80 Superchips performance centres, where trained technicians can undertake the remapping procedure.

Customers can be assured that the Superchips conversion is covered by a full Customer Service Guarantee and an industry-leading 12 month / 30,000 mile supplementary vehicle warranty.
