I am using a Haltech PS2000 unit for my 2JZ/S13 swap and I want to use the stock S13 gauges (for now). For the Haltech output, I need to know the duty cycle and pulse-per-cycle of the tachometer, and if I can figure out how to use the speedometer, I will do the same.Thanks.

I think I found that the stock tacho uses 4 PPC...but nothing on speedometer.

Anyone?
