Hooked it up again to the Bosh Motronic. Seems like I have a lot fewer parameters to view than in a more modern car?
Get some info from the OBD, but little in depht on engine management etc.
This is a professional tool. Any ideas what to look for?
Also tried the Texa scanner. It can not scan boxster 2.5. Works from 2.7 onwards.
Will order a new AOS and change it, just in case.
Any thoughts?

Can you look at:
Short and or long term fuel trims??
O2 sensor signals??
Throttle position sensor signal??
MAF sensor signal??
Camshaft deviation??
Actual camshaft position??
Does it have freeze frame info on the codes??
Also a Vacuum test with a vacuum gauge would be helpful.
Not only the reading of the needle but the action of the needle.
