As the title says. I am planning on converting to cop within the next 2 months. However I am not sure which setup I want to go with. Simmons Tuning uses a COPmini controller that has a board that plugs into P28 ecu and then you repin the ecu wiring and ect. For more info you can find them on FaceBook Simmons Tuning and Performance is the name. My other option is Hondata's COP retrofit kit but the controller is outside the ecu. Hondata is about $390 Simmons Setup $380 for the diy setup. What do you recommend???
