problem ecu swap with op-com

[teuton]

Hi m8s

got an 2006 Chevy (C2) where I have to change the Ecu. The car here in Mexico is more or less like a Corsa C in europe.. I got a resetted used ecu and everything goes fine until this "new" ecu has to be programmed. This step always fails. after failed programming op-com wouldn?t read any data from the ecu apart from the pin number. I tried with another used ecu and same thing. Does any1 have a solution for this, please?

Thank you for your time and help, I do appreciate.

used corsa ecu must be reset or unlocked before it will code to a different car....you need pin code for car the replacment ecu is coming from...go to engine ecu programming menu and enter pin....reset and the exit to immobiliser menu...then enter pin for this vehicle ..(readable in dash eeprom menu)..then program using immo+ecm option.
