hi guys, have a problem for you. is there any way to reset the rev counter? Reason being, mine is running about twenty thou to high with engine running normally.

`91 camero 350 z28
accel hi pro coil
accel 8.8 leads
K&N filters
Dynomax headers and ram air mods next.

 

Is the error consistant or does it fluctuate up and down?

 

yes it is. it shows about 15 thou at idle and goes up to about 45 thou at 50 mph. I have also just changed my dist. module as it crapped out on me over the weekend. This high rev reading is getting progressivly worse.

 

I've got a very similar problem iny my 82 Z28, https://www.thirdgen.org/techbb2/sho...hreadid=136420

Told to either get another tach/cluster, but I think I am just going to install an aftermarket tach ..

thanks for the advise Rob, may do the same thing myself. About how much do they cost (after market that is)?

 

It really depends on what you want. they range in price, anywhere from about $80 to $400 ... the one I'm installing I got for $100 at PepBoys, it's a SunPro, white face, 10K rpm tach, internal LED shift light, with an external shift light. It's also a slim design, so you can mount it in tight places, like on the dash of an old school truck or something.

You can get a nice Autometer tach for around $150-$200, has an external shiftlight.

thanks for all your help Ron.
