I have my S100 up and running on my S50B32 on pretty much the baseline tune (which isn't half bad really, just very conservative) and looking at the real time chart, I see some odd behavior from cam2.
In the chart below, the yellow line is cam1's target, and the teal line is where cam1 actually is. Both lines follow each other closely. Cam2's target line is not visible since its zero, but cam2 is definitely NOT showing any indication of tracking it properly.
Anybody see that before? I'm kinda limited on my diagnostic ability till Monday when i'll grab the decent meter and some backprobes out of the toolbox at work.
I ohmed out the two sensors and they seemed within range of each other. Once I get the meter and probes, I plan on looking at the AC voltage on the cam1 and cam2 sensors, and taking a peek at what the cam2 advance/retard solenoids are up to.
There's no audible or "seat of the pants" weirdness when it's wandering back and forth either.
My theory barring any kind of hardware failure is that the offset could be wrong and the cam is actually bottomed out at full retard and bouncing along as the solenoid commands movement against the stops. Plausible?
