Support for FLASH, EEPROM, MPC data – optional tuning and EGR OFF
The ECU 55566390HN is used in Opel Corsa D models. The offered unit has been cleared to VIRGIN state, which means it contains no vehicle data and must be coded before use. Activation requires a GM-compatible diagnostic tool such as TECH-2 or OP-COM.
It is possible to pre-program this ECU with customer-provided data. We support FLASH, EEPROM and MPC files – allowing full recovery of the damaged ECU and preparation of a new unit in Plug&Play mode.
On request we perform software modifications – including CHIP TUNING and EGR OFF. The housing has been renovated: cleaned, repainted and sealed. Despite reinforced protection, the ECU should not be exposed to moisture.
