About remapping
The Hyundai i40 accounts for 151 files in our catalogue, almost entirely the 1.7 CRDi diesel in its 115 and 136 hp variants. It is a mid-size saloon and estate aimed squarely at the European business market.
Stage 1 makes up 137 files — an exceptionally clean profile — followed by 21 EGR off. The ECUs include EDC17C08, EDC17C57 and EDC17C53, plus MED17.9.8 on some units. All work starts from the original read of the ECU.

How does the 1.7 CRDi respond?
It gains mainly in mid-range flexibility, which suits a saloon covering high mileage. The map is kept measured to preserve reliability.
Are the 115 and 136 hp versions different?
They are output levels of the same engine, distinguished by calibration. Both are covered in our catalogue.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
