Finding one that reads off a lead that just temporarily clips over a spark plug wire would be nice. An automotive tach would be looking for a 4 cycle, 4 cylinder, wouldnt you just divide or multiply a reading X2 if you had such a automotive tach?
I used to work on Stihl chainsaws years ago at a rental yard. We had this portable LCD tach that just clipped over the spark plug wire for dialing in the carb. That was a 2 cycle though. But you get the idea.
I'd be afraid to just take a off the shelf generic tach and try to integrate it into my electrical system. I know I'd smoke a CDI or something I cant afford to replace, or not know what I burnt and have to take it to the dealer. But.....thats just me and my luck with electronics.
