BMW X1 ECU remapping
701 files available

About remapping
The BMW X1 accounts for 701 files in our catalogue, dominated by the 2.0d four-cylinder diesel across its output levels — badged 16d, 18d, 20d and 25d — with the 20i on the petrol side. It is a compact SUV used mostly on road rather than off it.
Stage 1 makes up 625 files, with 95 EGR off and 68 speed limiter removals. The ECU range spans EDC17C06, EDC17C41, EDC17C50 and EDC17CP02 on earlier cars through to the more recent MG1CS201 and MD1CS001.

What does an X1 gain from Stage 1?
Mainly mid-range torque, which is where a compact SUV spends most of its time. It makes overtaking and joining faster traffic noticeably easier.
Which badge corresponds to which output?
The 16d, 18d, 20d and 25d are different output levels of the same 2.0 diesel. All are covered in our catalogue.
Does it affect xDrive?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
