About this file
Stage 1 on this engine refines the ignition timing and the fuelling across the rev range; on an engine without a turbo the gain is modest, the throttle answers sooner.
The file is listed for the 142 kW, 193 hp version of the BMW E46 328i. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For this calibration of the BMW E46 328i we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
