280zbeeT Posted February 26, 2011 Share Posted February 26, 2011 Ive been Google this recently, cant get a definite answer, but one forum a guy said he has a friend who has the haltech and the tech II but Im pretty sure he meant installed at different times.. so my question is, I have a haltech e11v2, is there any use for the tec II?? or is it only one or the other cant run both at the same time? thanks! I dont really understand if tecII is just an ignition system like MSD but much better and Not a CDI ignition or if its a ECU.. that why my question may seem stupid to you guys Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted February 26, 2011 Share Posted February 26, 2011 Tec2 is a full function stand alone ECU. I can't see using both (if it's even possible) unless a function is fried on one. Quote Link to comment Share on other sites More sharing options...
