Hey Matt / Grippo / others,
I'm not seeing any AFR readings in tunerstudio v 1.006. I have a version 2.0 Microsquirt running code version 3.77. WB O2 sensor is an AEM UEGO, part number 30-5130. I have custom WB selected, set at 0.5 Vdc at 8.5:1 AFR and 4.5Vdc at 18.0:1 AFR per the manual: http://www.aemintakes.com/instructions/ ... 0_inst.pdf.

When I say I am not getting readings, I am looking at TS with the engine OFF but the ignition ON. With a multimeter I can see the voltage rise from 3.0V to 5.0V as the sensor warms up but the TS reading stays steady at 7.0:1 AFR.

I may have read elsewhere that the engine needs to be running to see O2 readings because the O2 sampling algorithm is keyed off of RPM. Is this true?

Also, can someone please inspect my MSQ and ensure that my system is set up to properly read O2?

Thanks in advance!
Rich

This is true. I don't see anything blatantly wrong in your settings, but if you have zero RPM, you have zero sampling.

Just closing the loop here -- AFR reads just fine while the engine is running.
