22nd Jun 11 Andrew, some feedback on the CRD-T unit for the Beemer. First impressions are; you can immediately feel the additional torque that the tuning box provides, as a huge wave of torque gives you a shove in the back from low down the rev range. Continue accelerating upto 4000rpm and the engine doesn’t run out of power as easily as it used to. The tuning box now enables the car to be driven more economically by using the additional torque produced lower down the rev range. I can change gear at 1300rpm through the gears very easily without labouring the engine. The engine pick and response is better without any flat spots or hesitation. The engine feels smoother and more responsive Dare i say it, the car now drives and feels more like a petrol engine rather than a diesel, with two exceptions, the large torque it produces and the economy! With mixed town and motorway driving i can achieve 700 miles to a tank of diesel averaging 52mpg. I have also tested the economy by driving at 60mph on the motorway and reset the computer at the start of the journey. 150 miles later it showed 62.5 mpg. Fitting the box is very simple. I haven’t had any EML or smoke from the exhaust. Its currently set on Map 4+20% 😉 Cheers Mark
