I have no doubt the Xshift can support over 1000 HP. Heck my stock motor had to be close to that at the crank before I pulled it. It really shouldn't have much issues making way more than that as well. However there are no big names out there racing running megasquirt. Not that it means anything at all but there is an implication there that perhaps it may not be suitable for builds at a certain point. If I hadn't run into some freak ignition issue I would still have the Pimpxshift on my truck now.I've tuned a couple of my neighbor's projects on the Holley. The software is slicker, which you'd expect from a big entity like Holley. I'd certainly run their stuff if I needed all of the supporting hardware. My feeling has been that PxS is an excellent solution for up to about 1000 hp, and the nearly-plug-and-play aspect (and cost) is awesome for milder applications. Beyond that, you're starting to need some ignition behavior that the basic MS3 hardware CAN support, but it's all built into the Holley, and works plug and play with the Holley hardware, so it just makes more sense.
That said, because my RPM requirements are low, if I had the bottom end to support it, I feel pretty certain I could sneak the red truck past 1000 crank hp on the PxS, especially once I get the CNP hardware on it.
Unplug the dumb RABS +1PxS is all the controller you need. Just order the solenoid and pigtail from Stinger. Wire it up and enable boost control. There's a little bit of tuning required to get the initial target openings at various rpms set, but it's not hard.
BTW that erratic vss is likely caused by the RABS module. I tried a lot to get it sorted out in the white truck then gave up and left RABS disconnected.
Yeah, just need to add it to the list along with wiring a button for 2-step/launch control.
Dang I never knew that. When I had the pxshift I just had my 2 step on a button. Worked perfectly.I didn't have any luck getting a button for the launch control working. I just use the brake pedal (it comes setup for that) and a low mph shut-off. It works fine for doing a burnout (light brake pedal, once there's some wheel spin it shuts off), then launching (hard brake pedal).
The pushbutton circuit is actually shared with the PRNDL position signal, so when you mess with it, the transmission won't shift. You'll have to send the PxS back to Stinger for them to modify it internally for it to work (something has to be clipped). I decided "Nah."
