BMW M4 Stage 1 Remap
On BMW M4 naturally aspirated engines a Stage 1 remap refines the ignition timing, fuelling and throttle response maps. Without a turbo the power gain is smaller than on turbocharged engines; the difference is felt mostly in throttle response and the mid-range. No hardware is changed and the original software is backed up.
It depends on the generation and the stock output. M4 engines with 431–500 bhp reach 500–530 bhp with a Stage 1 remap; the largest gain is +69 bhp (F32/33 M4 - 431hp). Pick your version in the table below.
