alright would the cylinder positioning sensor throw the stock tachometer off, i tried installing a 89 crx si cluster into my 89 dx hatch and the tach wouldnt work. i found out that the two wires coming off the dizzy for the CPS were backwards, so i switched them around, would that cause the tach to be off?

so basically if the CPS wires were backwards would it throw the tachometer off?

 

anybody???

 

c'mon guys help me out here

 

if its wired up correctly i wouldnt think it would, does it seem to be off?

 

you could say that, it would only go up to three grand, and dont tell me the ignitor is bad cuz its brand new

 

i dunno maybe there is a loose connection or somthing or it might be something wrong with the cluster

 

As far as I remember, the tach signal is produced by the ignitor and not the CYP sensor. My guesses are
that maybe the connection on the ignitor isn't great
You have a faulty tach wire
Your needle on the tach is sticking when it hits 3k
your tach is shot
