Actually Im retarded. Tach signal comes from the POWER TRANSISTOR. Look at my diagram:
Pin 4, run it to your Microtech then to the Tach. Theres two different types of power transistors though, a 7 pin and 8 pin. Still might want to try an inverter though.

Think i'm in deep problem cause i'm not running a power transistor, i'm using aftermarket coils
-
hmmm Im really not sure man. Power transistor is in the stock setup. Microtech comes with the coil packs right? In which the microtech controls the coil packs right?
-
On a stock Galant with stock Galant ECU(96-98) Pin 31 is the tach signal wire on the ECU and its a white wire. It splits off, one end goes to the tach at the gauge cluster, the other goes to the 2-wire distributor connector which is the power transistor portion of the distributor. The wire on the gauge cluster should be a black/yellow wire.
On a stock 2g the tach wire is Pin 58 and its still a white wire. It just splits off, one wire goes to the gauge cluster tach and the other goes to pin 4 on the stock 7/8 pin power transistor.

yes I saw the two wires of the distributor, one is white and the other is black, they're on a separate plug, i tried to put the microtech signal wire on it but doesn't work, i don't know if i have to hook up the stock ecu back.
Take a look on www.microtechefi.com

mine microtech is an lt8, i don't know much about wiring
-
That diagram didnt help much. Are you using the MXS coil packs? If so it shows the tach being connected to the two.

These are the coils that i'm using
CAM ANGLE SENSOR WIRES,RED,BLACK,YELLOW,YELLOW/BLACK

If all the CAS wires go to the Microtech, just connect the tach wire from the Microtech directly to the tach. If that doesnt work try using a tach inverter. Stock 90 turbo 1g E/T/L had a tach inverter.

I did that already, i will check the tach inverter, you know were i can get one?in the states?
-
Off a stock 90 Eclipse/Talon/Laser. Autometer makes one too.

Ok seth thanks for you help, iwill check if i can get one

I wired up my tach directly to the Pin4 on the power transistor with no luck. If I hook up my pocket logger I have a tach there but the tach in the gauge cluster never works. Im going to try to wire up the tach inverter I have tomorrow.
