(I have an sr20det by the way)

so i swapped my 1990 tach out and put the 1992 180sx tach in.

I started the car up to test to see if it is ok.

here is the problem, When i turn the key to accessory mode, the tach automatically jumps to around 1000 rpms, Then when i start it, it reads 2500 rpm for the idle.

what can be wrong?

can i not use the 180sx tach in my 240sxz gauge cluster??

another intersting thing is I plugged up the whole 180sx gauge cluster and when I turned it to accessory mode the speedometer also jumped to like 10kmh and the tach jumperd to 1000 rpms

what could this be?

is the gauge cluster bad or is there some way to recaliberate the gauges?
