I'm completely new to tuning. I have an 04 Expedition police package with the 5.4L 2V; it's a 4x4.
I bought an SCT Livewire TS+ tuner in anticipation of the work I'll be doing on this truck; I want to improve low end torque and get better gas mileage - it's averging about 11 mpg over the last 10k miles.
I don't understand all the "gauges" my tuner reports. Can anyone tell me what the MAF count is counting? I do know what the MAF is and what it does, I just don't know what SCT is counting for this display. FWIW, I asked SCT. Here's my question to them, and their answer (in bold):
"MAF counts – Assuming this is the Mass Airflow Sensor, what is MAF counts telling me? Honestly I myself am not sure what the counts are. I do know that they go up and down with the amount of airflow past the MAF sensor."
so, Here I am. any input will be appreciated. thanks for your time.
