So I want to put my 2G MAF in. I don't have any sort of fuel controller except for an AFPR. The car has a stock ecu and 450's right now. Can I make everything play nice by turning up the fuel pressure? The way that I see it, is that the ecu has no way of knowing that the reason it's seeing a lower airflow signal is because a different MAF was installed. It just thinks the engine is requiring less air. The stock ecu also has no ability to monitor actual fuel pressure. I'd guess that if I was able proportionally increase the fuel pressure to match the decrease in airflow signal, it should work right?
Also, based on the assumption of fuel pressure rising 1:1 with boost pressure, if the airflow signal is reduced and fuel pressure increased as stated above, would this still be true? Or wouuld it need to be like 1.25:1? I wouldn't think so because boost pressure and airflow aren't directly related to each other, they're more like close cousins. And also because the fuel pressure rises 1:1 with boost regardless if the base pressure is 30 psi or 60 psi.
