Hello senior tuners
I tried to set AFR value.
As attached pic, I set the high RPM and high Load target AFR value around 11.9~12
But the actual AFR is 10.8 or so (NTK AF gauge and Innovate AF gauge)
Do I have to set another map to change the actual AFR value ?
Assuming stock air intake tract and MAFs are in place, adjust fueling using, Fuel Tab>Compensation Main. If it has aftermarket intakes, will need to work on Airflow>General>MAF Calibration. Get a nice smooth MAF transfer calibration that gets the fueling near your targets, then use the Compensation table to fine tune at various load and RPM. I just started working on tuning my 2011 Pathfinder this afternoon, running pretty darn well now and it is pretty close fueling wise now. I will start my own thread and have some suggestions for the scanner setup that I came up with and is working well. Idle/Low-load and Cruise, dialing it in off fuel trims, WOT dialing it in off the Wideband AF Sensors. First time tuning one with HPTuners, but I have tuned several of my person Nissan/Infiniti vehicles with Uprev since 2013 so the process is well known to me.
This is after about 4 rounds of fuel tuning. The average fuel trims are fairly close and it holds very close to the WOT air/fuel ratio target.
