So i just installed an android head unit, and i got a blutetooth ELM327 adapter from the supplier with it.
now i plug the adapter into my car, am able to pair it with the unit however i get no data.
i checked in the torque app settings and it shows the bluetooth device is paired and connected but it is not communicating with the ECU.

anyone have any adivce/info on this?
is it because my car is an early '95 model and i have no way of getting it to work?
or is it maybe something in the specific adapter that is no good?
if thats the case can anyone link me to a good (known working) one to buy?
is it something somewhere in some settings that needs to be changed?

The ELM327 needs supporting software that you can find on a torrent file or purchase

The software would go into a laptop or a android device that yours may not be able to except or load

the first level of the ELM327 software is the basic CEL code recording and erasing before getting into live sensor data

The present installed software may require purchasing a authorization key to open that higher live sensor data level

all good, i got it working after just a little more fidling around.
i had another bluetooth ELM327 adapter in my other car (exactly the same as this one) but thought i would try it anyway.
i tried it and it works.
and the new one i purchased works in my other car.
but for some reason they don't work the other way around.
my old one works in both cars, and the new one only works in my other car.
i have absolutely no idea why, they are supposedly exactly the same.
but the why does not matter as i have one working in both cars so all is good!

OK so what is the mass air flow rate for idle and wide open throttle in both grams per second and the voltage DC at the MAF sensor /ECU input

This would take some time and the voltage may not be available as a PID

The MAF at idle should be a little over 4.0 g/s at idle
