Target idle lambda

[Katiejot]

Anyone with an ep3 running a kpro able to help me out?
Have a P0135 fault for primary o2 sensor
replaced the sensor and fault won’t clear
I see my target lambda at idle is 7.35:1
is this what it should be? As I see people online saying it should be 14.7
When the car is running on the graph it says 14.7
Help please 🤯

That is way to rich at idle. It needs to be much closer to 14.7.

On PRA calibration it always says 7.35:1 idle target its weird but you cant change it. I dont think it has a negative effect on idle, your P0135 must be something else there is an option under closed loop to disable it it says : disable P0135 (O2 heater). I have it disable but i dont have primary O2 i dont know what it really is "O2 heater" ?
