Hello, I got an OBD2 plug and the demo-SW used by Kurt. Which is not possible – with USB via an RS232 adapter. So – other laptop with serial interface, SW installed and already running the thing, more or less. We tried it on the Y22XE and on the Y25DT and got quite well with it. Now my questions to Kurt: Is there somewhere a table with target values – I tried the search, but did not find it. OBD2 plugs for VAG driving The OBD interface is actually standardized – or does Opel go its own way. If the USB version is working, the newer OP-COM SW verse 080827 should also run, which is looking for a USB interface (including drivers) in the test. LG robert
