If you are a whiz at deciperhing the code of the typical Auto ECM and really understanding what it does - then go for it.  But, for the vast majority of us  - we'll keep flying with Tracy's EC2.  Nothing hidden and besides the ECM on autos are generally not redundant.  I first flew with an after market HALTECH EFI - a good system, but it did fail completely (fortunately I was on the ground when it did).  I was glad to be able to get an EC2 from Tracy with redundancy.
