car is running better today since i scaled back the ve table because it was running way to rich despite the graph saying its way lean. wrong math? 23-08-02 16-55-24.hpl[ATTACH]. 135192[/ATTACH]

I understand the ve table is wrong. What can I do to fix it? Scanner reads lean and no matter how much fuel I put into it it reads lean. I have fuel trims off until I get my fueling closer.
Engine displacement and Injector size vs fuel pressure and injector data and any other associated injector related tables all need to be fairly accurate to get the airflow model to make sense then and only then will VE table start to make sense
ac pressure wideband Im assuming. Looks like you may have an exhaust leak or too little pipe after the sensor messing with your readings. Or the math is wrong in the config on my end.
My wideband is ran through my a/c pressure pin from the ecu. When logging my afr error is mostly 30% in the red. If I add to the ve table it doesnt get any better but I can tell its running rich plus my 02 mv were in the 900's. So I pulled fuel out and it ran better. Im not sure if my math is wrong or the sensor is getting false info. my log shows all the red under afr err.
