MAF wish list
Posted: Tue May 15, 2012 1:15 pm
I've been talking with James and some customers about improving MAF support, and wanted to get a wish list thread started. This would apply to changes in both MS3 and MS2/Extra. What all would you like to see in such a MAF mode?
My own proposals:
MAF uses a table of voltage vs airflow in some sort of recognizable unit - or better yet, several recognizable units (standard cubic feet per minute, lb/min, kg/min, etc)
Tuning via the MAF transfer curve and AFR table 1. MAF transfer curve is editable as a standard curve rather than a sensor calibration, with option to save and load transfer curves.
VE table, if used, functions as a RPM/load correction table. 100% is no correction.
Support for MAF wired to MAP input pin for MS2 / MicroSquirt / MSPNP applications.
Decouple closed loop boost control from fuel load so that it would either use the MAP sensor in MAF mode, or if no MAP sensor present, use a MAFMAP approximation for boost.
