Karsan Bus ECU Tuning Files
Karsan builds minibuses and midibuses for city and regional service, best known through the Jest, Atak and Star families. Every Karsan controller in our list is a Bosch unit. They range from the older EDC7C1-C2, EDC7UC31 and EDC16C8 through the EDC16C39, EDC17C49, EDC17C69, EDC17CP52 and EDC17CV41 to the newer MD1CE101. The table below shows the modules we support on each one.
The most common requests are Stage 1, DPF Off, EGR Off, AdBlue/SCR Off, DTC removal and speed limiter (Vmax) removal. Some Karsan setups manage AdBlue in a separate aftertreatment unit, the Bosch DCU17CV51, and that file is processed on its own. Read the original file with your own tool and upload it. The automatic analysis then confirms which modules are available for that exact software before you order. Emission-related modules are meant for off-road, motorsport or export use where local rules allow.
Karsan ECUs and supported services
10 Karsan control units are supported. Each row lists the modules available for that unit.
The exact module availability for your vehicle is confirmed by the automatic analysis after you upload the original ECU file.
Modifications that disable emission control equipment are intended for off-road, motorsport or export use. Removing or disabling such equipment may not be legal for road use in many countries; checking local regulations is the vehicle owner’s responsibility.
Frequently asked questions
Which ECUs are used in Karsan buses?
Our Karsan list covers only Bosch units: EDC7C1-C2, EDC7UC31, EDC16C8, EDC16C39, EDC17C49, EDC17C69, EDC17CP52, EDC17CV41 and MD1CE101 for the engine, plus the DCU17CV51 aftertreatment unit. The exact ECU depends on the engine and build year, so check the ECU label or identify it when you read the file with your tool.
Is AdBlue Off possible on Karsan buses?
The AdBlue / SCR / NOx module is listed for the EDC7UC31, EDC17C49, EDC17C69, EDC17CP52, EDC17CV41 and MD1CE101 engine ECUs, and for the DCU17CV51. On vehicles where AdBlue is run by the separate DCU, that unit's file is handled separately from the engine ECU. After upload, the automatic analysis confirms whether the module is available for your software.
Can the speed limiter be removed on a Karsan bus?
Speed limit / Vmax removal is listed for the EDC16C39, EDC17C49, EDC17C69, EDC17CP52 and EDC17CV41. It is not listed for the EDC7C1-C2, EDC7UC31, EDC16C8 or MD1CE101, although Stage 1 and DTC removal are available on all of these. The analysis of your uploaded file shows the final module list.
Is DPF off available for Karsan?
DPF off is supported on: BOSCH EDC16C39, BOSCH EDC17C49, BOSCH EDC17C69, BOSCH EDC17CP52, BOSCH EDC17CV41 and BOSCH MD1CE101. Euro 3–5 vehicles without a particulate filter do not need this module.
