Tach Signal Interface for LT1 and LS1 Conversions

Tach Signal Interface unit is capable of recallibrating most tachometer signal to make them work with tachometers originally designed for a different number of cylinders.

For instance, if you have put a V-8 into a vehicle with a factory tachometer that was originally equipped with a 4 or 6 cylinder engine, the tach signal interface would be able to alter the tach signal so that the factory tach will read correctly.
