O2 Feedback Control 1.17 Firmware
«

Does anyone else have a problem getting the O2 feedback control to work properly with the new firmware?
I tuned this particular car a while ago, right around the time that the series 2 came out for this platform and the O2 feedback control worked as expected.
Now I started with a new map and converted it over to 1.17 and since then I have not been able to get the O2 feedback to work properly.
All of the basic parameters are being met and I have set this function up on countless other cars, BUT this car will not generate any feedback value, no matter what parameters I input.
I have the O2 sensor input wired in as O2 #2 and the injectors are set for feedback from the #2 O2 sensor.
I checked the accel and decel pump values and they are both 0, so it should not have anything to do with those values.
The first bit in the status byte seems to be fluctuating from 0 to 1 constantly, is there any documentation on what each of the bits relates to?
Any help getting this sorted out would be great!
