I just fix'em Chris, no magic involved. I sent the EC2 back with zero programming of the map table (factory default settings). *IF* everything else is right, this is how it is supposed to work and very little programming (sometimes none at all) is needed. Most engine teething problems start with some detail not being right in the installation (there are dozens of possibilities) and the builder starts trying to correct it by adjusting the EC2/3. If it seems like the EC2 is almost impossible to adjust, it probably means something is amiss. Sounds like things are back on track now and I'm glad its going better.

Tracy et al,
WHAT ARE YOU DOING TO ME!!!! I am not quite sure how to act. In the last chapter of the continuing saga I informed all of the broken ground wire to my ECU. How I had to send the unit back and how I not only scrambled the brains of the EC2 but also of the EM2. While you had it I received the fuel pumps from RWS that had been back ordered to replace the noisy MGS(?) pumps with push on hose connections <yikes>. I installed the new pumps and much better plumbing to them a couple of weeks ago while waiting for the electronics to return.
Well, I got my electronics back and installed them all back in the plane day before yesterday......NOW, here is the scary part. I turned on everything, placed the mixture in the middle, gave two shots of primer, hit the start switch......AND IT STARTED.....IN LESS THAN ONE BLADE.....kinda like, uh, well...a car engine <g>.

Also, the new pumps are significantly more quite....just an added perk. OAT today was 100 + and my temps stayed good. I added two four inch fans under my oil cooler to pull air through which is helping keep the oil temps lower longer. The coolant temp has not been an issue at lower power settings since I installed the larger radiator/heat exchanger. Oil is still running over coolant but I can let the engine sit on the ramp (where an electronic thermostat sitting on the strake read 132 degrees) at a moderate idle all day long and not worry about it.
Oh, yes, I rewired the ground wire that broke and am confidant (ok, confidant with fingers crossed) with the current install.
Go figure.
All the best,
Chris Barber
