  • I've finally done it!
    The tachometer in my FX16 is fixed and working great with my Link Atom X ECU. Watch me go through the learning process and stumble my way to a solution. I cover everything you need to diagnose and repair your Toyota tachometer, including meter movement calibration! You can make your tachometer work with any modern standalone ECU or replace a broken controller from another Toyota and then calibrate it to be accurate. You can have the tach show a 4, 6 or 8 cylinder engine on the stock tachometer.
    Sit back and enjoy my 3 month struggle of finding a solution to my tachometer woes.
    Hit like and sub if this helps you out!

    Super cool project. For future reference, you don't need a big box of resistors with switches like what you did to test resistance values. You can buy potentiometers that allow you to turn a knob to vary resistance to do the same thing. Once you have the exact correct resistance, you can record it with a multimeter.

    11:13 that tachometer is not from an AE101. That's from an ZZE110 (98-02 US 1ZZ engine). It accepts the low voltage signal, because 98-02 get the signal from the ECU, as all of them use independent coils. The board is slightly bigger, because many electronics changed on 1998. Also, it has an external temp gauge. That's what the LCD displays.
    On an actual AE101, you still need to do the resistor mod, as the AE101, the signal comes from the Igniter, and it is a high voltage signal.
    Nice video.

    The needle/spring setup is built onto the board of the tercel/paseo/cynos/sera/starlet clusters unlike the corollas, so the sweep/range resistor only needs to be changed if you want to change the faces (turbo starlet cluster has a higher redline). *saves video to favourites *

    And when you said youre using the coil for a signal, how are you doing that? I have a 20v swapped 86 i'm looking to use a link ecu with and was planning on figuring out the tach with it, but im not sure how or where i would connect the tach to a coil for a signal.

    On AE86, there’s a hard stop at around 9500 rpm. So I could install needle at below zero rest position. Then move needle to highest rpm until the hard stop makes the needle slips on the axle, do this a few times and see that it goes back to zero when it springs back.
    However, I’m dealing with a strange tacho right now. It is working correctly when powered, but without voltage, the needle spring is very weak so needle deflects around zero very easy if I lean the cluster housing. Not sure how to go about that?

    Hi, I have a AE82 FX with a 4A-C and a half broken gauge cluster (nothing besides the speedometer works)
    I want to get a cluster with a tachometer, but I don’t want a standard FX-16 gauge cluster due to the 7500rpm redline vs. the 4A-C’s 6000rpm redline. Is there a way I could transplant a AE86 SR5 tachometer into a FX-16 gauge cluster, along with my current cluster’s speedometer?

    Hey sushpants, the tachometer in my ae86 reads about 200rpm high across the range according to my megasquirt. Would it be worth it to try to adjust the tension on those springs? Also when I accelerate in the car through the 2000 to 3000 rpm range the tachometer sort of stops around 2300 sometimes and then "hops" up to 28 or 2900. Any idea why that would happen? Any suggestions would be much appreciated! Awesome informative vid!

      Do you notice the needle rising up at all when ignition is switched on and have you done the low signal resistor mod?

      @@sushpants I don't belive it raises at all with either the oem ecu nor the megasquirt with the key in the on position not running. I still have the factory distributor when running the oem of coarse or the megasquirt so no mods to the ignition system at all.

      @@sushpants I'm actually almost positive the needle stays absolute zero with the key on. Maybe its just because its old as dirt, not sure.

    I've just swapped a 2zzge into my ae92, but the tachometer isn't moving at all. Would I just need to swap the resistor for a 22kohm one to make it work?

    TC4452V. there's your booster. Unless it needs to be high and open, instead of high and low; in which case, and ordinary logic level P channel MOSFET.

    Hi I've got a ee90 corolla and I just installed a 4age silvertop into it but I cant seem to get my tach to work....it only moves on hi revs bandit doesn't go back down till engine is idle can u help? Any ideas. Please and thanks.
