Default AEM 1012 vs. AEM 1052, Whats better about the 1052

My S2000 came with a AEM 1012 ECU when I purchased it. I've seen the 1052 and was curious if it is worth upgrading? I did a little research, and the only real difference seems to be size, and ease of install. It has all the same features best I can tell. Is the 1052 Faster? If anyone has had the 1012, and then upgraded to the 1052 wouls you do it again? Thanks in advance!

If you're going to upgrade, skip the 1052 and go straight for the Version 2...

On the 1012 injector drive #3 doesn't work. You have to set it up on inj.1,2 & 4,5. But that's no big deal really, just an FYI.

I think most of the issues I was having were because I had a sick engine, and I blamed it on the 1012. However when the OEM motor died, and I swapped in the built one, I haven't had any problems at all getting it tuned properly. Even cold start works well.

Version2 eh? I may have to look into that...
