I'm running into a very similar issue; I can get it to start using NB inverted crank signal, but it idles like crap. My MS and VVTuner are getting the same RPMs though, and Rev says my MS has already got the 5v pullup. Was the ultimate solution to split the cam and crank signals to go to the MS and VVTuner separately, instead of going through the VVTuner to the MS? Or was that only necessary to fix the RPM reading issue? Mine shows that it's targeting around 20 degrees of advance, and it's actually getting around 46 degrees, which sounds very similar to what cpolly was running into originally; how did you guys fix that?

I bypassed the ms board all together. I pulled everything I needed from the ms side of the factory harness connection point. So basically intercepting the signals before they are even getting to the ms board. I drew some pics of the factory plugs and exactly what was needed on the page before.
