Ok, so i measured the voltage across vs+/vs- and ip+/ip-. I also tested a few more things. the engine runs fine at part throttle up until 1450rpm, then the engine starts surging at any speed at part throttle, but runs fine at full throttle. So, that being said here's what I came up with:

vs+ idle +.5v, drops to +.39v while surging
ip+ idle pretty steady at +.47-.5v with the occasional drop to 0v. at 1300rpm it picks up to +.65v with the occasional drop to 0v. while surging it goes back and forth from +1.07v to +.7v
