BMW 1 Series F20 - 2015 - 2018 118i 136hp (1598cc) — Stage 1 Remap
Stage 1 re-calibrates the ECU software — boost, fuelling and ignition maps — within the factory hardware's safe tolerances. No hardware changes are required.

About the BMW 1.5 / 1.6 turbo petrol (N13 and B38: 114i, 116i, 118i, 218i, 316i, 318i)
BMW's small turbo petrols power the entry levels of the 1, 2 and 3 Series: the 1.6-litre N13 shared with PSA (2011–2015) and the three-cylinder 1.5-litre B38 (2014 onwards), from 102 to 170 hp with hardware largely shared across outputs.
How a Stage 1 remap works on the BMW 1 Series F20 118i 136hp (1598cc)
Stage 1 recalibrates boost, ignition and fuelling. Lower outputs such as the 114i and 116i can approach the 118i level; low-rev torque fills out noticeably. The calibration stays within knock limits.
Pre-remap checklist
- Timing chain and tensioner on the N13 (a known Prince-family issue).
- Carbon build-up on the intake valves (direct injection).
- Ignition coils and spark plugs.
- Boost leaks and wastegate.
This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.
