Juanra can be to anyone that changes is the way he is managed and that depends directly on the fact that you eat your immobilizer, that is, there are some that command the pump current, others the initial injection pulse directly in the injector, and another command the spark. Others use a key signal to unlock an internal start switch. I know that the injection pulse can be unlocked, jumping the box that is the serca of the injection range, the direct cables are removed and put on, the two ends that are short, but of the others I do not have it very clear, I will try to look for the information to put it in any post.
