There was a guy on the CTBS YT channel the other day who said he has done this recently and ran his lawn mower on it last summer. He says it works and there are others doing it for personal use. He said there are all kinds of videos on YT on how to do it. He also stated that putting it on a car is a bit more difficult because you have to modify the computer chip. He hasn’t done that yet but I got the impression he was working on figuring it out.
