The venerable Land Rover Discovery Series 2 Td5's rugged nature and off road capabilities have ensured the model's enduring popularity with the motoring public. However, even in its acclaimed Td5 format, few could ever label the 135 bhp, Series 2 model as 'potent,' especially when overtaking or towing with heavy loads. This is why Unichip Europe is delighted to announce a new 'Sport Conversion' upgrade package for the 2.5 litre, five-cylinder Td5 Discovery, designed to transform the car's on-road acceleration and its off-road performance.
Central to the conversion is a brand new, advanced specification Owen Developments Garrett turbocharger, allied to a specially mapped Unichip 'U-Connect' supplementary engine management system. Designed as a like for like swap with the original Td5 turbocharger, the totally brand new Owen Developments Garrett unit features a considerably higher flowing compressor and exhaust turbine housings, enabling the 2.5-litre, five-cylinder engine to produce significant power and torque increases without mechanical strain or turbo lag. The other crucial component in the package is a 'U-Connect' plug and play Unichip ECU, designed and developed specifically for the Td5. This unit comes pre-mapped by Unichip Europe with adjustments to fuelling and turbo boost levels to maximise performance throughout the rev range. Fitted in minutes, courtesy of its especially developed wiring loom, the Unichip's ECU map is the end result of months of dyno and road testing, towing and off-road assessment to ensure optimised settings and reliability.
Dyno testing has shown that Unichip Europe's Land Rover Discovery Td5 Sport tuning package produces a dramatic performance improvement right throughout the rev range. Brake horsepower increases from a tested 127bhp at 3776rpm as standard, to 176bhp at 4000rpm, representing a peak gain of 49bhp over the standard car, making the Discovery feel considerably more sprightly at high revs. This extra power output has not come at the expense of torque, because the Unichip Europe tuned Land Rover Discovery manages to produce more torque than the standard car at every point in the rev range. Peak torque increases from 217lbs/ft at 2919rpm to 279lbs/ft at 2957rpm, equating to a 63lbs/ft gain. Peak numbers are only half the story because, such is the effectiveness of the conversion, that from 1700-4200rpm over 200lbs/ft of torque is always available, making the package perfect for towing or off-road use where low rev 'grunt' is at a premium. It also transforms the in-gear acceleration and flexibility of the Land Rover Discovery Td5, enabling swifter, safer overtaking and a much more dynamic driving experience. This has been proven by in-gear acceleration times figured during road testing, as it shows that the upgrade shaves nearly 4 seconds from the Discovery's 3rd gear 30-50mph acceleration time.
Crucially, at a time of soaring fuel costs and despite the considerable performance hike, extensive road testing on the Unichip Europe Land Rover Discovery Sport conversion for the Td5 indicates no fuel consumption penalty. Overall fuel economy improves marginally, thanks to the extra mechanical and electronic efficiencies realised by the conversion.
Priced at £1396.00 fitted (excluding VAT), the conversion suits all manual and automatic Land Rover Discovery Series 2 Td5 models produced between 1998 and 2005. In addition, the package is also directly compatible with the Land Rover Defender Td5. The Unichip U-Connect ECU package can also be purchased separately as a performance enhancement for the Land Rover Discovery and Defender Td5 and is available now directly from Unichip Europe or from one of 35 Unichip dealers across the United Kingdom, priced at £630.09 (including VAT). For peace of mind the Unichip Europe Land Rover Discover Sport upgrade is covered by a 12 month/12,000 mile warranty.
