Dilemma. Auto to manual conversion on 99 ex. I searched but found no results for this question. I want to chip my OBD2-b P2P auto to manual, is that possible, i heard it wasnt because of OBD2, maybe im mistaken. Should i chip it or buy the manual version of the P2P, or use the P72 (i read that will work for the auto to manual too if you want everything to work correctly).
