Hi.
I wonder if someone can help? I need to tranfer software from old ecu [astra g 1.7dti isuzu 2000] to new second hand ecu[astra g 2002]. Using Galletto 1260 I can read both ecu's and write to them both but engine will not start until I write original software back IN. I have both pass codes to reset ECU if need be ,tried addapting with opcom still no go. Below are the numbers of old and new ECU both have diffrent part numbers. Original ECU is non aircon, new one has aircon in options and I'm getting error code and EML light hence trying to write original soft. Can someone tell me if it can be done? Thanks in advance for any input.
