    Question ViPEC or Motec

    I am confused on these two ecm's. With the Motec you can use it w/o a aftermarket fuel pump pressure regulator. With a ViPec riva's fuel pump pressure regulator kit is a required part along with the ViPec and the Motec can be used w/o a pressure regulator. Am I correct or did I miss something for the use of the Motec? I would like for some one to post ALL the additional parts ( injectors, regulators, sc wheels and ect.) that are required to get these ecm's working correctly. It would be great for someone to list what parts goes with what s/c wheel I am totaly confused.

    Tommy, Jerry is running a FPR and recently added injectors (or soon will be). I believe this is the same for the other Motec guys running the big wheel.

    It's a billet piece used to block off the stock fuel pressure regulator on the fuel pump module. This piece comes with either the RIVA or R&D external fuel pressure regulators.

    Tommy, with either ViPEC or MoTeC you must use the aftermarket fuel pressure regulator.

    You can run either with the stock supercharger impeller if you choose to do so but of course performance increases dramatically when boost increases. If you use any aftermarket supercharger impeller then you are also going to want an aftermarket intercooler and a BOV.
