Does anyone knowif the pettit chip itself is interchangeable with the m2 ecu. I mean will the pettit chip plug into the M2 ecu and run right, i would assume they both use techtom to reprogram the ecu. I'm doing this because i can get the ecu for a good price and the upgraded chip from pettir is only $49. I would get a pfc but dont plan on any crazy mods. I email pettit but not sure when they would respond.
