I recently bought the tein flex z 16 way. Didnt know there was a 32 way option but its all good they work pretty good. I also bought the EDFC pro , keep in mind the motors and GPS are sold separately. I bought from redline360.com but just a heads the motors they sell that go on top are m12/m14 motors and the correct ones that go on top at m12/m12. Currently waiting on motors to get system going but excited to get it going and see how it works on the car
