BMW X1 sDrive18d Stage 1 Remap
On BMW X1 sDrive18d diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. sDrive18d engines with 150 bhp reach 190 bhp with a Stage 1 remap; the largest gain is +40 bhp (F48 sDrive18d 150hp). Pick your version in the table below.
BMW X1 sDrive18d: Stage 1 figures by generation and year
Year / chassis: F48 - 2015 - 2018
| Engine | Power | Torque | Gain |
|---|---|---|---|
| BMW X1 sDrive18d 150hp | 150 → 190 bhp | 320 → 400 Nm | +40 bhp |
Year / chassis: (F48 LCI) - 2019+
| Engine | Power | Torque | Gain |
|---|---|---|---|
| BMW X1 sDrive18d 150hp | 150 → 190 bhp | 350 → 400 Nm | +40 bhp |

GP Power ECU applies the software at its workshop in Hukou, Hsinchu, using EcuPrime-developed files; workshops can also order the file directly.
About the BMW 2.0 diesel (N47 and B47: 116d, 118d, 120d, 318d, 320d, 520d, X1, X3)
BMW's four-cylinder 2.0 diesel is the brand's most common engine, used in the 1, 2, 3, 4 and 5 Series and X1, X3 and X4 as the N47 (2007–2014) and B47 (2014 onwards), from 116 to 231 hp. Hardware is largely shared across outputs.
How a Stage 1 remap works on the BMW X1 sDrive18d
Stage 1 recalibrates rail pressure, injection, boost and the torque limiter. The gain is especially clear on the 116d, 118d, 316d and 318d outputs. A full low-rev torque curve results, matched to the 8-speed automatic; the character moves towards the next output up.
Pre-remap checklist
- Timing chain and tensioner on the N47 (located at the back of the engine, a known issue).
- Swirl flap mechanism and EGR cooler.
- DPF load and, on the B47, the AdBlue system.
- Boost leaks and intercooler hoses.
