PID Creation Help

[y2kws6]

I must be doing something wrong but I cant get both of my calculated pids to work. I have the wideband working but I cant get the fuel pressure pid to show up. Here is my code any help is greatly appreciated.

The pid doesnt show up in the list of pids. I'm sure that there is something I'm missing I'm just not sure what it is.

Thanks

Is that all one file you posted cause it has duplicated sections.

I think I fixed it. Here it is my revised code in case anyone else has the same problem. I'll test it tonight to make sure but the pid is there now.

I think that was my problem. I'm still kind of new to this. :D

[Tordne]

Thats looks better, not duplicated sections :)

psi units are already pre-defined for you...

if your definition of psi units causes a conflict or error message, you may want to delete that one line.

Otherwise should all be fine as Andrew said.

Thanks guys. The only issue I have is the when the voltage is moving around alot when I monitor the pid but the input into the ext.ad2 is steady. I have a swing of about 5 psi or around .15 volts up or down while the pressure is steady and the input is steady. Any ideas? My situation is similar to the one in this post. http://forum.efilive.com/showpost.php?p=28766&postcount=46
