don't assume that the ashspec ecu will damage the car, I daily drive mine as do many, many other people with the ash with no safety issues. Just out of curiousity, why is the jwt so much safer? Seedy and I both have biased opinions about the matter being that he has a JWT and I have an Ash, and we obviously both know they work well. Jwt makes amazing stuff, don't get me wrong, but do you really think the Ash would cause any problems because it's less 'safe'?
