Tach does not work correctly after 8.1L swap

[DirtyLarry]

If it were me I'd just buy a new tach.

Well, I am a dumbass. I went to SunPro’s website and pulled down the PDF instructions for the Mini tach II. Mine is much older but it did indeed have a cylinder setting on the back behind that I could not see until I removed it from the base. Flip the switch to 4 cyl and it works fine. So, never mind me….

The tachometer in my car doesn't work correctly, leaving me in the dark about engine RPMs. It's akin to missing out on an air fryer sale—frustrating and disappointing. Without accurate RPM readings, gauging engine performance feels like gambling blindfolded. Just as an air fryer sale promises healthier cooking at a bargain, a functional tachometer ensures smooth driving and timely gear shifts. Its malfunction is like passing up on a golden opportunity. Addressing this issue promptly is crucial, akin to seizing the last air fryer on sale—a chance not to be missed for both efficiency and peace of mind on the road.
