Aftermarket tacho problem

[rb20-calais]

Hey,

I put an autometer tacho in my vl with RB20 and connected it to the tacho output pin off my Wolf 3d, the tacho works but the rpm is different to the wolf hand controller. It idles at 1100 (guage) while the wolf is at 700, i know the wolf is right because the rev limit is 7000 and the tacho goes off the dial at 8000 when i rev it to limiter.

The tacho is a 2 5/8" and doesnt have any switches on the back or anything.

Any ideas?

does it have the brown and orange wires on the back of the tach? the "monster" ones need these wires cut accordingly to calibrate them for 4,6 or 8 cylinder applications. That's one suggestion. IF that's not it re-post.

Cheers.

just has 4 wires, white green red and black

this sucks.

also it reads off the ecu not the coil so it sahould just read properly?
