Default rev counter issues

Right got a problem my rev counter is giving me the wrong reading. When i rev the car it should be around the 2 grand mark but the gauge is saying 5. What could be causing this?

Has it just started doing this ?, or is it after some ignition changes ?
Either way the tacho is only a re scaled volt meter, so might have gone duff as they do often.

i have just done a turbo conversion so a new loom has gone in, the counter was working fine before i chaged the engine but the counter from the donner car worked fine. Just slight tap of the pedal is reading a massive increase in revs

Have you changed from a coil to a coil pack if so the old tacho will not work.

The car was running 3i management with coil pack now it's running rs turbo mfi management with Std coil. The only thing I have not changed is the dials will are still 3i.

That's your problem, the different ignition system, you need a rev counter for the type of ignition system, you can go from coilpack to std coil or vice versa without changing /modding tacho.
