obviously NM your are very aggressive for no reasons..... with your extra injector controller,you simply dump more fuel when oem injector run out of it(boost) that makes it a PIGGYBACK injector controller whatever you like it or not....not saying it is no good and will not work but it is a band-aid on a blister....like all other piggyback. Rapid bike is a good product in its idea but still a piggyback(that is where the industry is at right now). as for my mythic standalone, well it is not ready for public sale,still need a few tuning hours but final product will be great believe me,final pin-out of a/c harness is ready and plugged with many hours/weeks on it already.i don't mean it will be faster or out climb everybody.......it is a plug and play pull cord setup with 5 diffrent boost level at a flick of a switch with altitude compensation and brometric sensors for some turbo kit builder......exact same setup(and more) as a/c,yammy/polaris are using in their o.e.m. ecu and as far as i know,you can leave at 1000' up to 12000' with less h.p.of course(that's where turbos are usefull!!!) but sled runs like a champ all the way through! by no mean i wanted to be rude or bash your thread.... but moderate your voice tone with other companie's piggyback, it can bounce back in your face pretty rapidly.
Who gives a chit if it is a Standalone, Piggyback, etc, etc, whatever works. A true Standalone fuel system allows you to build complete replacement fuel, timing maps, control systems for your engine. I agree the Standalone systems are way to go in theory(I'm talking timing and fuel) but they are not ready yet, I dont think they will be for another 2+ seasons, and they still might not out perform some of the simpler set ups like NM's. If they can't do that, the only other thing that would interest me would be the ability to run premium and have fail safes to control detonation, like trim fuel, etc.
I've played with the RB3(probably longer than most), PL box, Boondocker, and yes even the Vipec you are TRYING to develope. I can tell you, you haven't proven anything until you come test in the conditions we ride in, Cam already warned you about that. I always make changes for the altitude I ride at. The dyno doesnt mean chit out here, too many variables riding in high elevation. We had to tune the Vipec in different load conditions up and downhill to get the throttle response where it needs to be. The most difficult area to tune was where the Vipec fades from TPS to the map sensor. Top end is easy to tune, especially with the large injectors this Apex sled has. I couldn't imagine trying to tune the timing and fuel without the bread crumb and trace function the Vipec has. We can accomplish more in 20 minutes tuning at altitude by feel(using a/f and EGT's as reference) than anyone can on the dyno, RB3 or Vipec. These things are nothing like a car.
The SDS system is stupid simple and the best option right now to make safe, reliable, ADJUSTABLE HP. The other boxes are too complicated for most people, the thought of playing with a fuel map, scares the chit out of most. At least the SDS is simple enough most can learn how to operate it in less than a minute. NM is right, the sleds we ride are a different animal, they are very difficult to tune, the load conditions, altitude and air pressure change so much it is nearly impossible to set up a fuel system to keep up. I'd rather have the simple option of turning a dial an 1/8 of a turn and riding out the rest of the day rather than switching maps, tuning on the computer or relying on others to make changes for me. Another advantage to his system is an unlimited supply of fuel for running higher HP, engine/turbo set ups. I'm going to run the SDS system until something else is proven to be better. I would rather be out riding or
than pissing with maps and computers on the mountain.
