MS3 Basic: No Tacho
My tacho isn't running. Its a 92 1.6 Miata with a 1.9 VVT swap (with stock 1.9 VVT Coils) and a MSLabs MS3 Basic.
- I deleted the ignitor and connected the yellow/blue wire with the black/white one, according to the "Definitive VVT swap" thread - Settings in Tunerstudio: Tacho Output enabled: on; Output on: Tacho; Fixed or variable: fixed; Speed: normal - I also put a 1k resistor in my diagnostics box (https://www.miataturbo.net/megasquir...43/) Any idea, what's wrong or missing? |
No sure how old your unit is, on most units the tacho is on the yellow/green, not on the yellow/blue.

I connected this yellow/blue wire, which is connected with the tacho, to the Black/white that goes to the ECU. This should give a direct connection from ECU to the tacho. Or do you mean any other yellow/green wire? |
No, this is wrong. The black/white goes to the ECU, but connects to null inside the ECU. You need to connect the yellow/blue from the igniter module to the yellow/green on the DB37, which is the tacho output.
|
This means, I have to unpin the black/white and connect it to yellow/green from DB37.
Do I need a resistor? |
Correct. No, you don't need a resistor.
|
Ok, I'll change that.
Thank you Dimitri. :bigtu: |
