There are VtoF and FtoV chips. To input other variables you would
need a microcontroller, with the capabilities of a FI controller.
How would it run if you just inputed MAF into MAP?
With no large lookup tables this could be made with 10830 cent PIC
and user adjusted with PC.  Of course since automotive product
would have to marked up 2000%.
