Sorry to Chris coupe for what happend.
I noticed a few attempts to mention this in his thread so I thought I would start a new one.
I thought that the vauxhall security was not breachable without the keys, I am sure I read somewhere that the chip in the key immobilizes by messing with the ECU when it is not present therefore making the car non driveable. You know if you swap your ECU your car will not go until the security is programed into it to work with the chip in the key.
Maybe this is only on the top of range ie GSI, Turbo Coupe not sure about that though.
Does anybody here know any better??
