Saw this and talked to the DIY guys a good bit at the PRI show, I know them well since I have been able to beat their BP engined MX3 cars with my rotary quite handily lately…

It looks like a modest update with some nice features like an internal MAP and baro sensor, it also has some more inputs and outputs.

The biggest feature to me are the on-board VR-to-digital converters to gather vehicle speed from OEM ABS sensors. With MS3X or MS3Pro, you have to either convert to Hall sensors or use a stand-alone converter box like something from JBPerf.

Having 1 5V supply per harness is also a bonus. It suck to have to jumper the 5V wire to both harnesses so you can power spare transducers ect.
