Michael, Landrover Freelander 2.2 SD4

Hi Rick Thank you for re-programming my V-CR unit for use in a Land Rover Freelander 2 after I had used it for three years in a Freelander 1. I had the unit fitted to the Freelander 2 on Monday by Church Garage near Winchester, who were able to turn the dial up to the maximum setting of 9. Yesterday was the first real test with a 170 mile drive to Dorset. I was very impressed with the power and flexibility of the vehicle and the ability to remain in 6th gear over some very hilly sections of the A35. Fuel consumption according to the computer was 41.8m, an improvement, but one I would like to improve upon still further. I bought the Freelander 2 in November, it is an 07 plate, 4-year old vehicle, with 33,000-odd miles on the clock. Again, many thanks. With kind regards Michael Cooper
