Hi all,thanks for a very robust reply from all concerned did not expect such a response,which a few years ago would not have to be asked.These questions will be common place in a few years,good technical information in this area is now critical.companies that offer diagnostic products need to start supporting this trade,with good technical info.Years ago when we used to do diagnostic testing and tuning a few companies we were associated with supported us with first class technical info and test procedures which at that time were class leading technology.Forums like ukat will I feel be so useful in this climate of constant technical advance.
Cheers to all
Mike hometune.
