Dakota Digital Universal Tach Adapter 1JZGTE 2JZGTE 4AGZE Signal Interface SGI-8E
UNIVERSAL TACHOMETER SIGNAL INTERFACE -SGI-8E
from Dakota Digital
Have you done a 1JZ, 2JZ, 4AGZE, BEAMS, or some other engine swap and lost your stock tach? This handy little piece is just what you need to get it working again. This device reads the tach signal from the new ignition system and calibrates it to whatever setting you want, and even will amplify the signal which is needed for some tachometers. We use these when swapping 1JZ or 2JZ engines into Supras, SC300s, S13s and S14s, or 4AGZE engines into Corollas, Celicas, MR2s, and so on. There are a lot of other engines swaps out there that also could benefit from this tach adapter box!
Here is Dakota Digital's description of this item:
The NEW SGI-8E Tachometer Interface Unit is designed to allow a factory tachometer to function accurately after performing an engine swap to an engine with a different number of cylinders or tach signal. If you are swapping out a V-6 for a V-8 and you need to recalibrate the tach signal from the V-8 to make it read accurately on the factory V-6 tachometer, the SGI-8 will do the job. With adjustability up to 16x, the SGI-8 is capable of recalibrating tachometer signals for nearly any engine swap combination. All setup, calibration and diagnostic functions are handled with the use of a built-in 3-digit display and integrated pushbutton switches.
Product not compatible with '86-91 VW Vanagon's and other similar models
Unit measures 4" x 2" x 1" and is designed to be mounted inside a vehicle.
FAQ - Will it work on…?
Unfortunately we cannot test every possible combination, but here is what you need to find out to see if this item will work for your application.
There must be a tach signal coming from the engine or ECU that can be fed into the box, the output can then be wired to any analog tachometer (this means is has a dedicated tach wire). It will not fix CAN BUS gauges that aren’t working UNLESS you are running dual ECUs.
Dual ECU engine swaps for cars with CAN BUS gauges (2JZ into 350z, E46, IS300 etc). – In some cases, the easiest way to solve CAN BUS gauges not working is to keep the original engine ECU as WELL as the new engine ECU. The new engine ECU runs the engine, but some signals are fed to the original ECU which can send the information via CAN BUS to the stock gauges (in particular the tachometer signal). This is done by using an SGI-5 (not an SGI-8) to read the crank sensor speed (magnetic or hall effect) and then convert that signal to one that the original ECU can read. This requires advanced wiring and unfortunately we do not provide that service, but you can speak to the guys at Tweak’d Performance about wiring harnesses for engine swaps.
