Well, why not put a little box between the sensor and the ECU? The little
box would intercept the MAF signal and output another signal based on a
lookup table. The advantage here is that you need to change little of your
stock setup.
I do microcontroller hardware and software design for a living. So I would
use a micro that has and A/D and EEPROM for nonvolatile table storage. The
analog output could be done with a D/A converter ... The lookup table
calibration would be done with PC (or laptop) connected with a serial cable
to the little box.
I may want to take this on as a side project if there?s interest ...
