anyone know my my 5 incher autometer tach is off by 700, it shows up as 700 more. ive tried everything. made sure the connection to the wire on the distributor was good, even tried new grounds and power sources, same thing.

once in a long while, it'll jump to normal reading, like once a month, but then it would only stay there for like 2 minutes , haha ghetto

any help would be great! thanks

blackhatchy

just leave it and do the math.

stripes777

been doing the math, for like 2 years, haha , just want something that works! lol

yup... i have the same problem... mine is off by like 200 or something, not to huge, but i think i'd rather just sell it any takers? $40.. haha!

rodrez.

Are you comparing it to a stock tach? The stock one is usually inaccurate.

if thats for me, then no, because i took it to fuel cut a couple times, , and from what the tach displays, its off...

stripes777

40 bucks for a monster tach with a light? if so , thats a hot deal man, ill buy another one and put in my dads camry, haha.

its off, i can tell from idle and vtec engagement. sometimes it goes to accurate, but only stays there for a while

its almost like it has 2 modes, perfect, and added 700, lol

sohc_boy

do u have the tach set for a 4 cylinder?

stripes777

im pretty sure, when i first got the car, it was perfect, now its a bit off

btw, the green wire is connected, the rest are cut off

Nextelbuddy

on the back of the tach there are little loop wires that each pertain to what cylinder car u have . for 4 cylinders u need to cut all of them , meaning no wire on the back should be together. all shodl be cut.

my 5" autometer tach is deadly accurate...I'll never get rid of it.

anyone wanna sell me a 5" autometer tach? pm a price

-Trinitron-

get an AFC...it will show you what rpm the ecu sees. Then you can tell which is really wrong and how much.

stripes777

anyone know if i can jus tap the green wire to a wire on the ecu, instead of going to the distributor? if so, which wire is it?

Jonathan_ED3

yep. you can.

it's a light blue wire in the back of the cluster.

this wire runs right to the distributor, so there's no need to go all the way there.

that's where i've got mine tapped in at, and like i said...deadly accurate

Jonathan_ED3

oh i thought you said 'cluster'. haha 'ecu' man i'm dumb.

should be the same color ont he ecu though.

Yep, that's how my autometer is set up. Cut them all and you should be good.

stripes777

ya theyre are all cut, except for the 4 needed wires( ground , power source, lighting and ****, and the green to the wire. wuts an internal coil? is that something thats cheap and can be easily changed?

i jus changed my cap and rotor for the dist. but the prob was there way before i did it
