Mazda 6 ECU remapping
459 files available
About remapping
The Mazda 6 accounts for 459 files in our catalogue, led by the 2.2 diesel including the SKYACTIV-D version, with the 2.0 MZR-CD and 2.0i petrol alongside. It is a mid-size saloon and estate with an engineering approach that differs noticeably from European rivals.
Stage 1 makes up 404 files, with 99 DPF off and 87 EGR off — a high maintenance proportion reflecting known characteristics of these engines. The ECUs are Denso units with SH7058, SH7059 and SH725X processors, quite unlike the Bosch or Siemens standard in Europe.

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.
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. Specific files are required.
Why so many DPF and EGR files?
They are known characteristics of these engines, particularly in urban use. Disabling them is not permitted on vehicles used on public roads, however.
