Mazda CX-5 ECU remapping
250 files available
About remapping
The Mazda CX-5 accounts for 250 files in our catalogue, almost entirely the 2.2 diesel including the SkyActiv-D and MZR-CD versions. It is a mid-size SUV with an engineering approach and electronics that set it apart from European rivals.
Stage 1 makes up 202 files, with 46 EGR off and 29 DPF off. The ECUs are Denso units with SH725X, SH7058 and SH7059 processors — quite unlike the Bosch or Siemens standard in Europe, which means specific files are required.

What is SkyActiv-D?
It is Mazda's diesel technology with an unusually low compression ratio, aimed at efficiency and emissions. It is covered in our catalogue.
Is a remap noticeable on a mid-size SUV?
Yes, precisely because of the weight. The extra mid-range torque reduces the need to change down when loaded or on inclines.
What makes Mazda's electronics different?
They use Denso ECUs with their own processor references, quite unlike the Bosch or Siemens units standard on European cars.
