Identification and scope
Bosch EDC17CP09 is an EDC17 diesel-engine ECU variant. BitSoftware describes its BitEdit module for BMW diesel EDC17CP09 files. Its BitBox vehicle list includes selected BMW E90/E91/E92/E93 325d and 330d N57D30 examples; the listing is tool coverage, not proof that every vehicle with those badges uses this ECU. Match the installed ECU’s hardware and software identifiers before selecting a definition or programming method. BitEdit EDC17CP09 module; BitBox supported-vehicle list, page 11.
AutoTuner’s compatibility list associates its BMW EDC17CP09 entry with a TC1796 processor. This is the vendor’s listed configuration; inspect the actual controller and consult the current tool documentation. AutoTuner ECU compatibility list.
What the calibration source lists
BitEdit lists accelerator-pedal torque requests and corrections, internal and external torque limits, powertrain and condition-dependent limits, monitoring functions, and conversion from torque to injection quantity. Its EDC17CP09 module also lists target lambda for smoke limitation, air-mass requests and corrections, and separate boost requests and actuator-control data for particular operating modes.
Other listed groups cover base and idle rail pressure, rail-pressure limits and control components; injector opening time and post-injection quantity; base main-injection timing and the interval between pilot events; and starting functions. Regeneration, EGR and exhaust-temperature sensor functions and a diagnostic-code editor are also listed. The publisher’s list establishes its module’s advertised coverage, not the presence, location, units or function of every item in every ECU file. BitEdit EDC17CP09 module.
File and programming context
BitSoftware states the supported file size as “4Mb” for this editing module. That product-specific statement alone does not establish the contents or completeness of a read made by another tool. Confirm the read method, memory regions, integrity handling and recovery procedure for the exact hardware, software and tool, and preserve an identified original. Do not transfer map addresses, scaling or calibration values merely because another file is labelled EDC17CP09.
For the general torque and fuel relationships, see EDC17 torque fuel and tuning basics. The Audi 2.0 TDI system examples describe different EDC17 installations and do not establish CP09 fitment.
