Hi George,
 
Before auto-tune, it was possible to tune = with an EGT,=20 or even by ear, but to really do it easier and better, you need an O2=20 reading.  Usually, this was a standalone gauge until the EM-2 came=20 out.  The EM-2 will read the O2 sensor, along = with dozens of=20 other things, so if you have an EM-2, then you don't need a standalone=20 O2 gauge.   
 
You say the EM2 is not quite = ready for=20 release just yet? 
 
The EM-2 itself has been out for a year and a = half or so,=20 and was just updated to get rid of the external box that = it used to=20 need.  Now it's all in the display=20 unit.  
 
How far down the track might that = be for the=20 EM2 and updated Auto tune ECU - your estimate,  
 
My estimate... need to be careful how I = answer this=20 :-)   For someone like myself, who has an EC-2 and EM-2 = already, all=20 that is needed to add auto tune is to replace the chip in the = EM-2.  That=20 should be available pretty soon, perhaps in a month or so when Tracy = gets back=20 to productive mode.  
 
The EC-2 that will auto tune without an = EM-2 is=20 likely a few months away still.  That's just my guess of = course.  From=20 what I understand, there isn't any way to upgrade an old EC-2 to=20 the next auto tune version, because the whole board is=20 different.  That's the delay now, getting a new board laid out and=20 tested.
