You soldering fool! WOW mbeach - you have gone above and beyond the call here! I am truly impressed by what you have done to get this nut cracked.
As for the Excel file, there is a size limit on attachable files, which I ran into when trying to post the ToD patent file. Moncha PM'd me about it, but of course I deleted the PM so I can't tell you what the limit is. But if you have just a data spreadsheet, it shouldn't be running into the size limit. Alternatively, you can try to post it in the Downloads section of the site, but I didn't have much luck with that, either. It seemed to want a URL for the file - I wasn't sure.
So although I absolutely LOATHE drawing conclusions or even being guided in my research by initial data, don't your findings suggest that we shouldn't send a static 68%+ signal to the clutch? That is, wouldn't it potentially be too much when you are accelerating from a stop? Or no?
The difficulties with the wiring harness shouldn't be a big deal. If we just need to tap into one wire (the one going to the ToD clutch), it's just not worth rigging up a dedicated connector. Of course, judging by what you've done already in the cable-making department, I realize you may not agree with me :-). It can still be a simple install to cut the clutch wire and splice in the switchable circuit.
Ok, good luck with the data interpretation! Let us know what else you figure out!
