Catalogue identity
The TuningService.uk ECU catalogue records EDC16C33 under Bosch EDC16 (catalogue record 1579, observed 10 November 2026). The catalogue name is an identification lead; it does not by itself prove vehicle fitment or software compatibility.
Application evidence
A used-parts listing identifies EDC16C33-4.21 Bosch 0281011841 with selected Mitsubishi Colt VI 1.5 DI-D and Smart Forfour 1.5 CDI applications. Microtronik also groups Mitsubishi and Smart under EDC16C33 in its 2023 Hexprog release. Confirm the fitted vehicle, ECU part number and software: the examples are not exhaustive.
Tuning and identification
Microtronik reported bench and boot support for Mitsubishi/Smart EDC16C33 in Hexprog II Tuner 1.0.87. That is a dated statement about one tool, not a guarantee of the same method with every programmer or software version.
Keep the original identification and read, verify checksum handling and match the file definition to the specific software. The shared ECU family does not prove identical Colt and Forfour torque or injection maps.
Read EDC16 torque fuel and tuning basics and EDC16 variant application and tuning differences for the shared context. Examples are not an exhaustive fitment list; check the installed ECU and current tool documentation.

The image source calls it EDG16C33, while another seller uses EDC16C33-4.21 for the same identifiers. The full suffix is not printed on the visible label.
