Note: Manufacturers full SmartShift installation instructions are available in the DIY part of the FAQ.
What is the SmartShift ?
The SmartShift model SS-300 monitors the engine speed and tells you when you have exceeded a pre-programmed limit. A typical application would be for a up-shift indicator light or audible beeper, with the RPM threshold set to slightly less than engine redline.
How does the SmartShift work?
The SmartShift connects to the tachometer signal to determine the engine speed. When the engine speed exceeds the preset RPM threshold, it will activate the output. The output will typically be connected to a dash mounted indicator light or beeper. It is also possible to use an existing dash light such as the brake indicator light.
Application for the Acura NSX
These instructions will show you how to install the SmartShift in your NSX. Once installed, the SmartShift will remind you to up-shift gears by illuminating the brake light on the dash board at a specific RPM threshold.
- RPM threshold can be set to any value from 4000 to 10,200 RPM, in increments of 200 RPM.
- Accurate to within 1%, better than stock tachometers.
- Works on all 4, 6, 8, and 10 cylinder vehicles with fuel injection.
- Output mode can be steady state ON or ON/OFF blink.
- Simple installation using common tools. No wire cutting required.
