pid not supported

[efilivesteven]

when im trying to do the ( rafpn ) the pid idle air flow correction ac off pn says that it is not supported and I get a line through the name on the map for the desired airflow

Im trying to log the b4307 so I can do the rafpn

Im posting a quick log I made so you can see what im talking about

For the pid CALC.RAFPN you need to select it's prerequisite pids (on PIDs tab, on CALC.RAFPN pid do rightclick->More Info to see which ones).

I did that but there is one pid it is saying that it doesn't support

it says I need these 3 pids

Engine RPM
Engine Coolant Temperature
Idle Airflow Correction AC Off, P/N (Grams/s)

the 3rd one is the one it says is not supported

...

Idle Airflow Correction AC Off, P/N (Grams/s)

...This one is CALC.RAFPN

on it do rightclick->More Info

this pid requires GM.IAC_LTPN_DMA.gps and GM.IAC_STPN_DMA.gps

did you select those 2 pids also...?
