JDM Tach Cluster not working!!!!!
 

I have a 1990 240sx with a Redtop SR, I got a JDM Cluster so I could have a working tach, but when I changed it with the US for the JDM Cluster, the tach still doesnt work but everything else work. Does any know whats wrong?

Thanks in advance.

wtf
 

yeah i am having the same problem, did you change the ecu also when you swapped the sr. i am wondering if it doesn't read the right signal.

I don't know but any help is appreciated.

The jdm s13 cluster mounts directly into the 89-94 240fb and coupes.

so my guess is there is an issue with wiring or power readings, when i first start up the car the tach needle jumps to about 1500rpm then drops to zero and doesn't move.

i love when the post goes.........
 

^ Bump bump bump ^

hey we got similar sn
but i been here first lol
:D

welp............
 

word from night (Gospel) is that the tach can't read the signal from the SOHC KA24's maybe others too.

I kinda thought that but wasn't sure, if you already did the swap then i really don't know what to tell ya.

but probably go with an aftermarket tach as suggested by Night.
