rev counter wrong??

[shamisz]

i've just put a set on clocks in my 1.0 12v corsa and the rev counters registering quite high and the limiter is way round past 7K?

any one know why?

i think its clocks from a tigra as the needles are orange.

cheers shane

i have the same dam problem mate. mine is showing that my car is idling at 3000rpm plus lol when its clearly only doin 900-1000.gotta be sumin simple

try this drive your car down the road and put your car in third gear at 30mph it should be at 2000 revs if it helps

a way i done it is see where the needle sits and what you think it is and work out the distance between the two. then remove the needle stop pin and see where it lays then pop the needle of and turn by the distance you think. then pop it on and push the needle stop back in.

is that all that needs doing lol, i thought id wired the thing up wrong? is there any reason it does this?

for gods sake people!!!!!
a 3 cylinder only fires 3 times every 2 revolutions, but a 4 cylinder fires 4 times every 2 revs, thus the tacho off a 4cylinder will over read by 33%

thats very funny and intresting as id not realy thought of that, but my clocks came from an sri and are now fitted to a 1.2 model car with a 1.6turbo lump.
my revcounter also flickers about abit, making me wonder if there was a wiring fault.
i literally plugged the clocks straight in and fired her up.
