For wideband to work (im still new to miatas) there should be a dedicated narrowband input wire in your harness. Use this wire and connect it to your Wideband O2 controllers 5v output. Next, in software you have to setup the wideband (as its still looking for a narrowband signal).

Anyone can chime in on this information.

My wideband is working fine. Both of the gauge and on TS. Issue is my tachometer isn't working.

COP's are working fine. Car is working fine. ECU is working fine but no tach.

I'm thinking the answer may be, don't know, to my request on how to fix this.

Let's try from another angle. Is there any way for me to check my ECU for the capability to wire RPM to an aftermarket tach or the OEM wiring just spliced in? Can I check through TS? Do I have to take it apart to see what modules/circuits are inside?

TunerStudio can't see the physical circuits in the ECU. Check with the guy who built yours to see if it has a tach output.

Will do, if I can. Bought it 2nd hand. Think it was a Reverant unit.

How hard would it be to add a tach output circuit if I don't have one?

Does it have a serial number on it?

Will check when I get a chance. Assuming it's located inside on the board?
