rev counter out of range

[munz_clio]

installed a rev counter with shift light only problem is that when my original rev counter reads for example 1000 rpm the rev counter reads 600rpm approx 40% less any guesses what it could be

and a big thank you to 16v_jon for explaining how to connect the tacho up no one else!!!!!

You've probably got it connected/switched to the 6 cylinder set up instead of the 4 cylinder (or visa-versa)!

Hope this helps.

link to said thread?
I'll need to be tackling this in a little under a year

the green cable from the tacho which was the rpm siginal was connected to the pin one on the coilpack plug going into the coilpack. pin 1, 2 and 3 have cables pin 4 is empty. . .

its on two cylinder setting at the moment tried three and four and it was to low

 

[theduck]

on four cylinder setting was it reading half?

 

[munz_clio]

on two it was reading half on four it was reading practically nothing

are you running standard engine management

 

[munz_clio]

yes it was orig' a 1.2 got it converted by ktec a few months ago so running a re mapped 182 but yeh standard

above is the link to the wiring of the tacho

the PPR is currently on two which runings around only 50 60 percent of what it should be. 3 and 4 are now where close

 

[Mark One]

sorry mate, I'd love to help but I can't. Thought I'd ask about management, because a few systems will allow you to run a tacho off that

 

[munz_clio]

well cheers for all your help

would anyone think using a better cable from the coil to the green cable which holds the siginal to the tacho could help a more accurate rpm reading
