Digital MAF signal simulator (Ditex AutoSim Pro)

hi I tried out a simulator on a digital mass air flow sensor, at first it didn't seem to work, then I thought it may be because the MAF needs a barometric pressure too or the air temperature. in this case on the Toyota that I was testing, I needed to also have the barometric pressure. this ment that I had to use a small jumper wire from the wiring to the sensor, the sensors power and ground also needed connecting with a small jumper wire too.
this way allows digital mass air flow simulation.
I hope this helps someone,
thanks for watching
