Default AFR wrong in TS, but Correct in MegaTune.

As the title says.

MegaTune recognizes the AFR almost exactly to what my gauge is showing.

But TunerStudio says 10.00, but the voltage reading is correct. I'm completely lost now.

I'm using a PLX M300 gauge with the wideband signal going to the ECU and its grounded on the back of the head. The car is a 90 w/ 1.8swap.

Tell us about the electrical grounds, specifically where the heater, sensor, and gauge are grounded, if the ring connectors are stacked, and where you tied the ground wires together.

Also as I said before, it reads the voltage fine, it just displays the wrong AFR. I'm guessing there is some sort of setting in TS that i need to change.

MegaTune displays the same voltage as TS, but also shows the correct AFR.

I prefer using TS so i'd like to get it working correctly.

You need to set up your wideband properly in the project properties.
