    PDM / fuseless wiring options?

    I know about the Racepack Smartwire. It seems awesome. What else is out there? Im interested in getting away from fuses and relays, partly as a nerd project and partly for article fodder for Race Magazine.

    The Rowe PDM60 looks good but is limited. Ive been looking at a budget PLC called Velocio which is damn cool and cheap, but can only handle 300mA so back to relays. The real advantage of Velocio is I can run a distributed network control via CAT5 cable or USB extension cable and get rid of nearly all the wiring in the car.

    What other options are feasible?

    How man circuits, amp capacity, etc. Cheaper side have a look at Blackbox PDM's, ECUMaster PDM, or Switch-Pros?

      I picked up one of the Rowe PDM60s which I was thinking about using it for basic functions such as lights and shit.

        I have the Blackbox. Works great but only 12 outputs.

          Motogadget do a couple aimed at bikes, they'd probably be great for a single seater or clubby
          "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

              There's another one called Motobrain motobrain.net which looks really promising. I have been following on and off but when I look he seems to have supply issues.

                I've been using it for ~4-5 years. Turned my rats nest of 70s BMW wiring into a breeze.

                  What do you (anyone?) know about Switch-Pros? Considering this for a race car with simple wiring needs: ecu, fuel pump, ignition, starter, fan, etc. None of the usual stuff like lights, wipers and the like.

                  This seems to be all I'll need and straight forward to use. No worries about switches and other hardware bits.

                    A lot of offroad guys in the US use Switch-Pro stuff with few complaints.
                    Rywire is another well regarded name, NOT cheap though. https://www.rywire.com/product-p/hp-powerbox-8441.htm

                      Havn't used one at this stage (might be doing one later this year) but in a quick look I couldn't find any bad stories about them.

                      I did question them about using to run an intercooler sprayer (with adjustable on and off time), they don't have it yet but indicated they would add it to their development list.

                        Thanks. That Rywire kit does seem expensive.

                          From all accounts it's good stuff though, apparently alot of top level drift teams use Rywire in the US as do a number of off road racers there. Iirc Vin from Hoonigans is running a Rywire PDM in his S14. They also use the Blackbox PDMs as well.
