Manifold pressure not change

Hi Jani,

I am using ELM327 to get Manifold pressure, if i open the monitor and type 010B it reads the correct pressure but if i go back to my text gauge ( input: manifold absolute pressure) it always read 100.

010B PID didn’t appear in PID search result as you can see in the picture. Also i don’t have MAF sensor but it is appeared in the PID search result in picture.


By default, RealDash asks for supported pids with 0100 and 0120 commands. The pids that are not reported as supported will not be used in rotation. You can remove the pid check by removing these lines from section of OBD2 XML:

<command send="0100"></command>
<command send="0120"></command>

Thanks it works.
