Hello all, a friend mechanic has asked me a hand to start to understand something of this world. Is not concerned with the tuning but basically the removal from the Ecu of the fap and the valve Egr.

I have read articles and posts on the forum, and as far as the programming on the bench, then via bdm, I understand that the programmers most well-known and comprehensive are the Ktag of Allientech and the BDM100 Evc . Am I wrong? are there others to consider?

Thanks
