Hi there - new to this forum! I recently bought a OBD2 scanner but I don’t know how to interpret live data from the tool. I know this is a complex field and I don’t pretend to be an expert. That being said, having some sort of reference in terms of normal values / reading would prove to be  extremely useful in preventing issues etc...Is there a book / Manual where to find these values for a 996 C4S? your help would be more than welcome! Thanks in advance

Probably the most useful in that context would be the factory OBDII manual, which is now out of print, but used copies come up for sale online from time to time.

Thanks JFP! Searched a bit online but I couldn’t find anything  ...probably there is a lot of knowledge in this forum about “normal” values and % for the most common readings in OBD2 in 996s...and that would save me extra bucks for other stuff (Porsche of course!)

To find what your looking for takes a lot of research and what you find about PIDs (Parameter IDs) on Porsche automobiles is minimal.

Much of the values you detect must have a conversion / equation to determine actual useable information. Software like Dramatic performs all of this for you. Apps for Android and iOS do the same, but are not as robust as Dramatic.

I have tried to find a factory OBDII manual without luck.

 

If you find anything out, share it.

Enjoy...

Thank you both Kdgic and Loren! I will stick to my basic OBD2 scanner and see what I can learn from it. For sure nothing compares to Durametric but I am not planning to invest that much money now. I will give it a try and see how it goes and what I can learn from it.  Nowadays these new OBD2 scanner are pretty good to be honest and give you a bunch of very useful data.
