I'm not too sure what the sequence is on engine start, it must command the valve closed somewhere in the sequence once engine is turned over on starter motor but I haven't looked at that side of it.
I have the datalogger set to (I think) either .75 or .5 second intervals to get around the file size issue after a long run logging. File sizes get a bit redic at anything more than that. That sample rate is too slow to really track what's happening on start though... I'm looking at the performance of the fuel system on open road running not fine detail!
It's a fair warning for the danger of the thing when pressurized though - 2000 bar is enough to cut solid crap right up.
