Mark VIII MAF Calculator

This is for the 80mm OEM Lincoln Mark VIII MAF. Ensure you stay at or below 86lbs/min max for the 1993-1995 EEC-IV and 64 lbs/min max for the 1996-1998 EEC-V.

If you exceed the max, you will need to Scale the ECU.

enlightenedYou can use this to calculate how much more, or less to change the LBS/Min flow of the MAF to address for the injector change. Since this is a direct cut/paste of a stock MAF Transfer, only the LBS/Min column is changed. Volts are kept out of the equation and are set in the tuning software as a 15.999v max in the top line on OBD-I Boxes.

enlightenedOEM Injector AHISL is about 24.192 lbs/hr in all years.

--- WARNING: NEVER EDIT THE TOP VALUE FOR MAX VOLTS OR A/D Counts (X Column) IN THE SOFTWARE, ONLY ROW 29 and DOWN.

LBS/Sec is LBS/Hr / 3600 - I like to use LBS/min but you can search how to convert for your liking.
