Check engine light general setup

Post by jasaircraft »

Hi,

So im finishing up a MS3 on a subaru and I have my check engine ouput wired up to a check engine light, I have now enabled it and im enabling each of the sensors i want it to check.
What should the normal values or procedure to know the values be(are they counts or volts)? fluctuation values?
Im using the diyautotune 4bar map sensor
GM IAT sensor
the subaru CLT sensor which is already calibrated on the thermistor and reading fine all the way to 100C
The subaru tps
battery
sync loss count

thanks in advance

My setup, I found the EGO too troublesome so disabled. This seems to behave OK but it is hard to say because i haven't had say map sensor fail to validate it is going to work.

It is a start which I hope you see preferable to no response at all

See in the bottom right of the settings page. You can make "status5" show the fluctuations or ADC count for each of the sensor inputs.
