Unichip Europe launches U-Connect performance ECU for BMW 120, 320 and 520D models


Unichip Europe launched a new performance-enhancing plug and play ‘U-Connect’ piggy back Unichip upgrade for the BMW 163 and 177 bhp, 1995cc, four cylinder direct injection engines used in the 120, 320 and 520d models from 2003 onwards.

Consisting of a specially premapped version of the renowned piggy back ECU, the Unichip makes subtle electronic tweaks to the BMW’s fuelling and boost settings to improve all round performance, without compromising economy or reliability.

Designed as a DIY fitment via its plug and play ‘U-Connect’ wiring loom, the Unichip is fitted (and removed) in minutes. It leaves no electronic footprint and is ‘invisible’ to main dealers during servicing and to ensure it’s totally tamperproof the ‘U-Connect’ unit can only be remapped by a qualified Unichip agent.

Rolling road testing has proven that a ‘Unichipped’ BMW 520d gains an impressive 19bhp and 40lb.ft (54 Nm) of torque over the standard car, producing a measured total of 188bhp, allied to a mighty 252lb.ft (340 Nm) of torque at just 3400rpm. Similar performance gains can be expected from the 120d and 320d models.

On the road this added punch translates into easier overtaking, greater driveability, and enhanced driver enjoyment, whatever the speed. With family use in mind, towing heavy loads becomes less of a chore thanks to the extra torque on tap, making caravanning, or trailering horseboxes a more practical proposition.

Unichip’s ability to refine the BMW’s key engine parameters via the U-Connect piggy back ECU has a negligible impact on the BMW’s 55mpg fuel economy. Tests have proven that fuel economy is unaffected by the Unichip U-Connect package, with drivers actually reporting a 5-10% better fuel consumption compared to standard.
