This should allow for a fairly close rough scale for bosch sensors in larger housings. Some fine tuning may be required, but so far the results look promising. You can specify the offset of MLHFM, or allow the program to find it automatically. When specifying the offset, make sure to follow this format:
0x[MLHFM offset]
Please, check the results before flashing, and report any problems or observations.
MAFadjust for Bosch sensors, by maZer.GTi and ddillenger
Notes:
- Fixed 16bit overshoot bug
-Fixed Hitachi bug, now results for hitachi should be ok
-New Version will write create txt file for copy and pasting into winols or tunerpro
-Please remember to correct the checksums prior to flashing.
-Failing to specify an offset for your MAF transfer function
will result in an automated search. Please verify results prior to flashing.
-When specifying a percentage scale,
use the change in surface area, NOT diameter.
-Unless specified, calculations are for Bosch sensors.
For Hitachi, please remember to specify that in your command.
Usage: mafadjust [yourfile].bin [old_diameter] [new_diameter] [0xMLHFM_offset]
Usage: mafadjust [yourfile].bin [increase_diameter_percent] [MLHFM_offset]
Usage: mafadjust [yourfile].bin [old_diameter] [new_diameter] hitachi
Usage examples:
-- 73mm MAF scaled for 83mm housing
mafadjust 8D0907551A.bin 73 83
-- 73mm MAF scaled for 83mm housing, MLHFM @ 0x10D72
mafadjust 8D0907551A.bin 73 83 0x10D72
-- 73mm Hitachi MAF scaled for 83mm housing, MLHFM @ 0x10D72
mafadjust 8D0907551A.bin 73 83 0x10D72 hitachi
-- MAF scaled for 30% larger housing, MLHFM @ 0x10D72
mafadjust 8D0907551A.bin 30 0x10D72
