Had one customer with an Astra G Z16XEP with HSFI 2.4 ecu , the ecu got wet with cooling agent which finally corroded the pins in M connector so decided is best to clone it into another ecu .
First read and write eeprom with carprog ,all went well ,the new HSFI 2.1 get the pin from corroded HSFI 2.4 ,then read and write flash with Galetto 1260 (done this a few times on other ecu's ,no problems) ,writing was done but after that the HSFI 2.1 is no longer recognised by carprog or galetto ,the older HSFI 2.4 is recognised , so I guess the ecu is bricked .
Carprog says connection error and galetto shows just a few lines instead of ecu data .
Is there a cheap solution to revive back HSFI 2.1 or I am at the mercy of someone having MDI /Tech2 ?
