PCM Input Signals Hi everyone, I'm new to this forum! We are a small company in Switzerland, building our own cars using an 1999 LS1 engine and a Porsche G50 gearbox.
We really only want to use what is really necessary and therefore I would need to know the following:
1. for what does the PCM need to know the fuel level in the two tanks? Will it work without the signal?
2. Same for the EVAP Vacuum Purge Switch signal: what is it used for and will the PCM work without that signal?
I assume that some of this stuff is only used in the ODBII diagnostic mode and we won't use that anyway!
Thanks for the help!
