Tach Adapter - Rat2

Tach Adapter - Rat2

$ 89.95


o you finished your Gen4 3SGTE, 2GRFE, 1ZZ, or whatever swap and it is now making tons of power and plenty of noise. The only problem is your tachometer isn't working. There are a handful of options to overcome this problem but now, the simplest and easiest way to effectively use your factory tachometer is here, at an affordable price!

We have developed a simple, plug and play adapter which allows you to use your factory tachometer with your swapped engine in your Toyota. Plug in the tach adapter to the output from your new ECU then simply connect the output from the adapter into your original tachometer! 

Not only does the Rat2 Tach Adapter effectively modify and change the signal for your original impulse tach, being 100% digital it creates the ideal signal to drive the OEM tach and provides a smoother response than any other tach adapter available.

This is intended for cars equipped with the older, high impulse tachometers, such as the 85-89 AW11 MR2, 91-99 SW20 MR2, or any Toyota which uses a factory igniter as part of its ignition system. 

  • True impulse signal
  • Silent operation - no annoying wine or humming
  • True RPM - Digital control means no approximation or 'tuning'
