You can use it for Bm3, MHD+ or Ecutek. It depends on how you wire it up to the CAN wires based on the software (bm3, mhd, ecutek) you will use. & programming the Reflex+ with the software if I remember correctly. For MHD+ and Ecutek the port injection is integrated with the DME. You will need a port rail kit or manifold for this.Which tune is the wiring for?
