Electromotive v Haltech v Accel v Home Brew

[Vogt Family]

Hi, it's me again...I am still looking to add a good FI system to a
turbo 429 that is in the works.  I would like some impartial opinions on
the different type of controllers available.  One thing I noticed on the
E-motive is that it has the capability to electrically control the
wastegate.  This seems to be a good idea because I could have it
fail-safe open and could also leave it open for normal driving to bypass
the flow restrciction of the turbine.  I would also like to have it
driveable enough that my grandmother could be comfortable in it, and
fuel efficient (as fuel efficient as a 429 can be) during normal
driving.  This is where I think the home brew system may fall short but
I don't know much about it.  Also, do any of these have adaptive learn
or am I just asking way too much of an aftermarket system?

Thanks,
Birken
