I have been playing with the 1227747 on my Flathead Ford for a month or so now, and am becoming very familiar with it and the tables and scalars and such, but I have been told it is quite crude compared to some of the newer ones. I am leaving the 7747 on the Flathead as I am too far into it to change now, and I like the simplicity of it.

I am contemplating installing a TBI system on my '68 Firebird this year which has the Pontiac 350 in it, 4 speed T10 and 3.42 posi and would like to start searching the local wreckers for a good ECM system to use.

I would like to hear what the best, or next best ECM would be to use today, the next gen as it were. Would there be a huge learning curve for the new ECM or are the tables and such still familiar? I like the 747, and it certainly would do the job, I just thought if I am starting from scratch, maybe I should try something newer.

thanks!
