Finn,

   It would appear that the way I wrote that seemed to 
suggest more than I intended.  It wasn't my intention to 
imply that Tracy's unit wasn't being successfully used - 
only to compare its numbers against the smaller number of 
flying MicroTech units.

   Indeed, when I get to the point being ready to start 
the engine, I intend to buy a unit from Tracy.  But I also 
expect to have to do *a lot* of tuning, before it's ready 
to transfer to the airplane.

   Paul was expressing concern that tuning the MicroTech 
was out of his reach.  The Mazda ECU already comes with 
good maps; and it "learns" as it goes, IIRC.  Am I 
correct in understanding that the default maps on Tracy's 
EC2 are regularly being updated?  Can they be transferred 
to older controllers?  Via firmware updates?

   As far as spontaneous mid-air shut-down goes, has 
that ever actually happened to anyone flying the factory 
ECU?  What sort of things won't it "like", that could 
cause a shut-down? 

   Perry, are you out there?

Regards,
Dale R.
