Speed Density "SD" vs Mass Air Flow "MAF"
Just been curious, if anyone have an idea,
if we can cancel the MAF, and use the speed density to calculate the density of the air by measuring the temperature air and manifold pressure....??!!??

IIRC MAS is more accurate, I ran MAP/airtemp and TPS on my turbo due to pipe sizes and because my tuner was more suited to that, If I had a choice again I would have run a MAS,the ability to change with environment far outweighs MAP,TPS,airtemp.
Edit, also we ran MAP because we did not think the MAS would read 16psi. this was never tested though.
