Im buying one and dont know how to install it. Please help me with this. ksThanl

 

Why would you install one when your TL already has one?

 

Aftermarket? Lol

 

I bought one with shift light. My car is stick shift

 

Reminds me of the 90s.. with tachs larger than my head back in the FnF days...

 

oh boy....

 

You can get an external shift light with out the useless 2nd coffee can tach..

 

reallly how i love the light on mi si

 

help me out. please

 

lol wow talk about tacky...... you cant tap into any cables on the inside of the cars ecu but u can tap into one of the cables from the resistor packs off the sparkplugs. i dont know how the unit u bought gets its tach info but the acura is totally digital.

 

actually kptech has a tiny pinhole shiftlight which would work very stealthfully

 

i smell rice

 

rice rice baby.. dum dum dum duh duh dum dum

 

:theghey:

I would die to see a TL with a big ass tach

 

I will do t, just need somehelp on the installation

 

why do you need a tach, you know you have one already, and can't you drive and look at the factory tach, but if that is what you like go for it

 

Do you have the tach already? Its pretty easy to wire up. 4 wires + the loop wire to specify the 4 6 or 8 cylinder. I do recall tapping into a green wire to get the rpm signal. Then there is power ground and lighting wires.

Btw this is from what I remember when i hooked up my 5" autometer in my gsr back in 2000.

I would really just look into the shift light and get the rpm chips 6.0-7.0

 

who have done it?

 

other than tapping into a sparkplug coil pack which i dont recommend... u have to get a an alarm module that breaks down the pulsing dc current form the computer that sends it to the cluster....then u may have a chance at making it work but other than that goodluck....i went through every wire in the book from the ECM/PCM and bcm and nothing contains the rpm signal wire in anything other than pulsed dc.....which i dont recommend playing with.

 

i dont get y people add it unless ur car tach is broken or u dont have one or if the one u have in the car doesnt keep up to the mods you made on the car

 

ROTFL!!!!! I thought this was an Acura site, not a Civic site

 

ROFLMAO!!!!! thank u spin!!!!!!!

 

I've had very good results using fuel injectors to provide the signal for the KPtechnologies shift lights. You just need to have a shift light that can work with a 1/2 ppr signal.

tripnbeats - almost all rpm signals are pulsed dc - why do you not recomend messing with them?

 

when you get it installed post pics

 

pulsed dc means its monitored by the computer through the CAN system its a digital signal until it enters the modules that decode them and show the info...like the stock tach on this car....the cluster is what decodes the whole "digital mystery" and gives you your info.....if u hook up an aftermarket tach to the digital line all your gonna get is a series of ups n downs in voltage from .1-5volts.
if you hook up to one of the plugs or injectors....thats not pulsed signal. thats just raw electricity going to the computer to be read compared and given to the tach in a digital manner. unless you have a module that reads and decodes the signal and its specific to give you tach reading....like an alarm/remote start bypass module for example...otherwise i wouldnt play games with it.

 

^^^ knows what he's talking about. Checkout www.directed.com

 

Pulsed DC means that if you put an o'scope on the wire it will generate a square wave (ie on / off) type signal - whether it be a CAN bus line, a fuel injector, a cam or crank angle signal, an ignition signal, a power window motor encoder signal or any number of other signals - the list goes on and on. As long as there is a distinguishable ON and OFF threshold it is a pulsing signal.

Of course you can't hook a traditional tach up to a CAN bus - you would need an interface module that can decode the CAN signal and pull out the tach information for that to work.

Plugs and injectors ARE pulsed voltages as they turn on and off as needed to control the motor. When using these signals as a tach reference (for remote start, tach, shift light, etc) you are measuring time, not "raw voltage". By measuring the period of the signal you can calculate engine RPM. If the signal needs to be doubled (tach is reading half of what it should read) then you can diode isolate seperate fuel injectors (180 degrees from each other).

I guess what I'm trying to say is as long as you have the right pulsed signal (one that directly references RPM) there should be no problems using it. I've even successfully used a crank angle sensor to drive a shift light with no issues. The shift light was capable of ignoring inconsistent periods so that the "keys" of the reluctor wheel didn't mess the shift light up.

 

KP you are correct..... i didnt think of that when i was flappin. now that u said that...i can hear my teacher in the back of my head when we were learning isolation methods for alarms n starters and issues we would come across and how to resolve them if we werent using bypass modules. but its still not something id tell suggest to someone to put in the TL

 

You say that now, but as soon as the OP posts pictures everyone on this forum will have at least a 6" tach mounted on their dash!

 

lmao..... i doubt that...but u never know. that would be funny to see.
