Can someone please tell me how this gauge works? and how to install everything? The instructions are in japanese or something and I dont know how to read them...

 

I have the instrucs in English. I can scan them and email them to you by tomorrow evening.

 

14.7 is stotch i think....i forgot if higher is rich or lean...

 

I´m using on, quite long time.
It´s very good. Not acurate has a wideband but it´s very good to make some adjustments during runs. Forget dyno butt during runs and you don´t have to spend a lot of $$$ all the time in a dyno.

I can´t find my instructions in english. Don´t forget to set your a/f metter to 13.1, he will have better readings.
The best a/f for my ITR is 12.5:1 during accelaration and 13.0:1 at WOT.

You´ll learn very fast how to use it.
