[Ecutech]

Anybody have any info on this old ecu? 3 plug, Red, Blue and White. What needs to be altered in eeprom dump? Which wire to cut from ecu or immobox? Never worked on this ecu type before. HC11f chip.
Is it just a case of filling all with FF or something else?

Original ecu was destroyed by voltage spike, secondhand donor ecu was not divorced from original car and unable to program with Tech2, even with security access. I have pulled the vehicle pin from the immobox. When trying to marry ecu to immo i get the error ecu is already programmed, function not available (not divoirced properly) The vin in the picture is the donor car vin. 

Either want to put the ecu in a blank programming state for tech2 or permanently remove immo.

Not asking somebody to do it for me, just advice from anybody who has worked on similar before. I think this chip is used in quite a few cars from Opel and Daewoo.

Thank You.
