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? |
Check the voltage on the analog output and see if it's giving the signal it should be.

how did you wire the brown wire to 2C?
|
I've soldered the brown wire using 18 gauge straight to 2c and I'very tried running it all the way through the firewall to the black ego1 input wire.
|
and that was a solid blue wire?
|
make sure you didn't confuse the serial wire with analog wire

Check the voltage from the wideband output wire to ground with a multimeter set so it can read from 0 to 5 volts.

Both analog outputs are providing adequate voltages. IM starting to think its a problem in TS or maybe my ecu pin

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? |
I changed the project properties to wideband (afr)
I set the ego control to 1 wideband from the normal ego port I calibrated the afr table. Still nothing The ego gauge in TS shows .16 volts while my multimeter read 2.8 volts right where I spliced into the ecu. I'm out of ideas... |
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 |
