Finnaly I got an OpenLogic Analyzer and I would like to learn on how to use it.
Just to make it interesting i want to learn how to get some data from my Terrano, something like fuel cut solenoid and the fuel pump rpm sensor (pump cranck).
So I installed sigrock and seems to support the OpenBench Logic Analyzer, now what, i just hack the probes on wires and start seing magic happening ?

How do I see the simple voltage changes and record them over time?
