mafsim
hi guys,
how exactly do mafsims work?
what inputs do they have? map and tps?
are these units just plug and play (all the same) or do they need to programmed to a specific tune? if so why?
cheers

MAFSIM is a box with microcontroller inside performing a speed density calculation based on RPM, MAP and TPS to generate a 0-5v engine load (MAF) signal.
Output can be modified to give usable output for various RPM and MAP ranges, TPS sense and range etc, but it does not simulate a specific MAF, so a custom MAF curve must be programmed into your ECU.
There have been some reliability issues - none causing engine damage but a few MAFSIMs lost their config for some reason.
