Okay, strange issue.
My DIYPNP MS2/Tunerstudio sees my OEM Lambda sensor okay, now swapped it out for my LC-1.

Setup my LC-1 correctly, wired into the 15DB socket then across to the O2 input on the mainboard, Tuner Stuido doesn't see it.
I have set tunerstudio to use the LC-1 default in the project properties and as a single wideband in the EGO settings, BUT the TS dashboard gauge sits at 10.1 AF ratio.
Soooo, got a multimeter and tested the voltage from the LC-1 brown wire in the 15DB plug and at the O2 input on the mainboard and I am seeing around 2.2-2.6 volts at idle (bare in mind it isn't tuned yet). So the mainboard is seeing the correct voltage, any suggestions?
Have I missed a setting in tuner studio somewhere?

 

Posted this on Nutz too, but you need to calibrate the AFR table in Tools>Calibrate AFR table too.

Do this and it'll work.

 

knew it was something easy

thanks
