I dare say they generally work to give gains though when it goes to plan, so im not saying its useless
As I said, Ive never looked into them Ive just plugged em in and downloaded the generic maps for a few people who didnt know how to do it or were too scared to have a go themselves. Not sure about the immobiliser information.
Evo Chip would be the way Id go too given the choice, I just put it up as a possible option, not knowing the full story of what was going on with his current map.
