Yep you are spot on with regards to decreased duty cycle when speed increases.
Not much need to keep pressure high if they will be spinning the same speed for typical on road use.
Advanced detection of slip would be the key here.
I am curious how fast the reaction will be when I test it in the snow.
The stall test isn't necessary, I believe the KOEO in gear, throttle pinned will accomplish the same thing.
Although there will be no pressure in the system just solenoid activation.
If you listen under the vehicle you can actually hear the solenoid buzzing at 50Hz.
I have heard some people incorrectly diagnosing a bad solenoid because they "think" it sounds bad with the buzzing. Its normal.
The peak is hard to see, I would have to throw a scope on it to capture it.
My DVOM does have a max value capture though, have to look at the manual but I believe it captures as low as 1ms.
I haven't viewed the values in FreeSSM long enough to notice how fast it is refreshing.
I will have to observe the conditions under which the line pressure solenoid frequency changes.
Haven't dug into it that much yet but, it was definitive and pronounced. All solid #'s 50,100 & 150.
The transfer solenoid and TCC never deviate from 50.
Will check again on the 2-4B Solenoid, didn't seem right to me that it was the odd man out either.
The link you posted to the cable is the exact one I bought. :29:
