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.

Dale you have got to be kidding?!
I think a brief survey will show that the vast majority is flying Tracy's EC.

Doesn't the car EC shut down the engine if it doesn't like what it senses?
Not a good thing in the air!
