The changed OEM Cd figure has no effect on the 0.17 figure since that was determined by coastdown testing done using that spreadsheet from Instructables. Actually my Cd might even be a bit lower than that now as I have installed a number of minor aero mods since doing that coastdown testing. The problem is finding a long enough, flat, and lightly trafficked stretch of road to do the testing on. Its all rolling terrain here, so I have to make a trip down to the coastal plains of SC to do it.
I'd have to pull my original data points out and plug them back into that spreadsheet to get the 0.00 CD figure, but that might be false accuracy since my original data was to the nearest second, not the nearest 0.1 sec.
