This Stage 1 ECU calibration is designed for the 3.0 SDV6 engine in the 2017 Range Rover. Built on the Bosch EDC17CP55 ECU and software 020068 (EU6 platform), it delivers increased midrange torque, improved throttle control and optimised boost/fueling strategies — ideal for heavy-duty, off-road, or towing scenarios. Flash-ready and checksum-corrected using OLS807.
