Tach 2x rpm

RE: Tach 2x rpm
was the tach replaced recently from a doner car? if the car was a 4 cyl. then there should be a switch on the back of the tach that indicates either 4 cyl or 8 cyl. I know the older 4 eye tachs had this never really looked at the 87 up.

RE: Tach 2x rpm
ya i got the same problem......., twice the rpm it really is. I also went from a 140mph to a 85mph speedo and now it reads wrong. I figured it wouldnt make a difference. The whole cluster is out of a 91, 4 cyl.
I like the 4cyl gauges better it keeps me out of trouble. LOL

Yes it does matter. If you change the speedo, you will have to change the speedo gear to correct the mph. Also, as numerous guys have stated already, the tachs in these things were the same whether it be a 4,6, or 8 cylinder. There was a switch in the back and that's all it takes to fix it.
