Chrysler C300 ECU remapping
37 files available
About remapping
The Chrysler 300C accounts for 37 files in our catalogue, and the 3.0 CRD diesel is the dominant engine by a distance: 25 files under its principal designation alone. It is a large saloon with an American air, powered by a V6 of European origin that responds well to electronic work.
Stage 1 accounts for 33 of the 37 files, with 6 DPF off as a complement. What stands out about this model is its uniformity: practically every unit carries the same ECU, the Bosch EDC16CP31, which greatly simplifies identification and the work itself.

What does the 300C's 3.0 CRD gain?
Mid-range pull, which on a saloon of this size and weight translates into more comfort when running loaded and more decisive overtaking.
Do all units carry the same ECU?
Practically yes: the Bosch EDC16CP31 appears across almost our entire 300C catalogue, which makes identification much easier.
Do you cover the petrol versions?
There is the occasional 3.6i file, but the 300C catalogue is overwhelmingly diesel. Ask us if you are after a specific petrol version.
