Buckingham-based technicians believe they could make London’s iconic black cabs both more powerful and more fuel efficient.
The Superchips company took the most recent version of the taxi cab, the LT1 TX4, which is powered by a 2.5litre, four cylinder turbo diesel engine, and aimed to boost both its driveability and economy. They analysed the vehicle’s Bosch EDC16 ECU and found several optimisation opportunities that enabled the company to fine tune the map settings to remove any inbuilt compromises while also boosting performance.
With their remap, the LT1 TX4 saw its torque vastly lifted from a measured 265Nm at 2,622rpm to a maximum of 339Nm at 2,352rpm. Power gains were also impressive with the car producing a measured 103bhp at 3,059rpm previously but with the Superchips remap it leapt to 3,479rpm.
Of particular interest to green car fans however, is that not only did the Superchips upgrade boost the performance of the vehicle but it also helped its fuel economy with fuel consumption gains in the order of 10 per cent.
Superchips is now offering the upgrade in a matter of minutes at its dealerships in the UK priced at £445. The conversion comes with a full customer service guarantee and a warranty.
