About this file
Stage 1 on the 520i 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 BMW E39 520i carries the 520i engine, 150 hp and 190 Nm from the factory. On this engine, Stage 1 usually gives about 165 hp and 208 Nm (+15 hp, +18 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For this calibration of the BMW E39 520i we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
