Yes, that's possible with the simulator. Instructions and binaries can be found here [...]</blockquote><div><br></div><div>Thanks, that's very helpful.</div><span class=""><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
The aladin/memomouse parser doesn't report tank pressure, because that info is not stored in the sample data.</blockquote><div><br></div></span><div>It is.
