Tunerstudio wont read wideband
So Im hooking up my LC-2 to megasquirt (DIYPNP 3) and I cant get tunerstudio to read it. The controller is grounded to Throttle body and uses the power window for 12v power. I set both the analog outputs to read 0v=7.35 AFR and 5v=23.59 AFR. I wired the brown analog output right to pin 2c on the ecu and the yellow to the DB gauge.
I did a free air calibration.
In tunerstudio i set the project properties to wideband(AFR) and calibrated the AFR to the LC1/LC2 default. In AFR/EGO control I set it to 1 wideband and EGO1=normal ego
Still nothing. The afr gauge in TS reads 7.4 while my DB gauge reads just fine. I even switched the analog output and the DB gauge is fine which leads me to believe its the ecu connection or a setting in TS.
Any ideas?
My car is a 2000 CA Spec. Are the Ca spec ECU pinouts different from the federal?

The LC2 has to serial CONNECTORS and 2 analog output wires (yellow and Brown). I connected per the instructions for the LC2 and DB gauge. LC2's yellow wire to the DB gauge's white wire. LC2"s brown wire to the ecu. Just for added assurance I went into LM Programmer and changed both the analog outputs to have identical settings. So far the DB gauge works great but i cant get it to connect to MSPNP2

The 2000 MSPNP (all states) should looking for the 0-5v signal on 2C (blue).
If you confirmed that it's going to that spot, and getting voltage, then I can only think youre not looking at the correct gauge in TS?

so when you're reading your voltage you see 5v, but somehow MS sees ~0v ( ?
going out on limb here and still suggesting you did not hook up your wbo2 output wire to the correct o2 input wire that TS is looking for.
what happens when you use afr/ego inputs > air:fuel ratio 1?

Exhaust gas oxygen 1 shows .16 volts
This is with the car set to acc after a short drive and the db gauge reading 17.4 afr
