You'll sell half a million kits overnight, given the package/app and micro-sensor are <$199.99 and does not need too much of a hassle to install (e.g without having to remove the gearbox).
^ Unrealistic but you get the idea. Can't imagine it being that efficient without retrofitting the IMS flange with "built-in micro sensor" anyway but could be wrong
Just built a website for the product and sell "paid advertisement" to shock absorber and alternator manufacturers (lolll). You'll get so much traffic during product launch you'll make enough cash with this alone I'm sure.
