Tachometer Fix

Newbie here. Just stumbled onto this forum while reading posts on the H.A.M.B. Seems like there is a high level of sophistication here, so I thought this might be a good way to open a discussion about a little product that I am making that resolves most tachometer issues.

Tachometer problems often occur when swapping engines, for example sticking a V8 into a car that originally had a 6-cylinder. Problems also arise when swapping in later engines with electronic powertrain control modules, HEI ignitions, etc. into earlier cars. The brute-force solution is to just replace the tachometer with one that is compatible. But what if you want to keep the vintage appearance, or you just like your old tachometer? After doing an engine swap on my car I was faced with this problem and came up with an electronic solution that would allow me to use my original tach. This received a lot of interest from other enthusiasts, *********************** It allows the use of a tach intended for use on a 4, 6, or 8 cylinder engine to be "matched" to a different size engine. It also resolves problems associated with many of the newer electronic ignitions failing to properly trigger the old tachometer. It is simple to set up and works for a wide variety of situations. ********************
