Do you have an Air/Fuel Mixture sensor monitor?  Even though the simple LED ones are not what I would call accurate, they are really very helpful (I don't like to fly without one now) as they do provide a relative indication of what is happening to your air/fuel mixture.   
 
Back when I bought the EC-2, I also got the AF gauge and sender that was offered.  When the EM-2 arrives, I won't need the gauge anymore, but for now, it's velcroed to the side panel as a temporary measure.  It seems to work better than I expected, though I'm spoiled by the wideband FJO AF meter that I have installed in my RX-7.   At the moment, I have no EGT, but I'll add a probe when the EM-2 arrives. 
 
Also a note on the tiny tach installation- I went ahead and wrapped the full length of the sensor wire around the coil wire when I installed it.  That came to about 7 turns, rather than the 3-4 that they recommend.  In other words, I haven't tried it as recommended.
