As mentioned in another thread. I have a L6 ecu with a stg 3 GGR chip in it that I want to swap into my L1 3dr. Stu mentioned it will be a straight swap but when I plugged it all in, as soon as the key is in the ignition position, the fuel pump fires up and I get full pressure at my fuel gauge. Tried to start it but it just wont fire. Plugged the old L1 in and no fuel pump running at ignition and it started straight away... Thoughts?

Cheers
