Buying a small tachometer to run some tests on my LIKE.
Going to check the idle speed with an Iridium plug and with the stock NGK plug - .
Also will check RPMs at some steady speeds before and after installing Dr Pulley slider weights.
Will probably keep it in my front glove box, pull it out & set it on the dash with some velcro when I want to explore things.
Digital is fine for my purposes. (Trail Tech)
