Ls2 engine control question
For the GTO, IIRC the cruise is controlled through the body module or BCM if you use the E40 ECM.
Just something to consider if you want to hook up your cruise control.[/QUOTE]
INCORRECT, I have a 2006 GTO LS2 & T56 with a Speartech harness and I am using a E40 ECM and John @ Speartech can turn on the functions to have cruise control using a E40 ECM without the BCM (body control module)

I wonder if it was because I was using an automatic and the E40 for use with an auto requires the trans controller?

What he explained on mine he removed my 2006 GTO program from my E40 PCM and flashed in a 2007 Chevrolet SSR tune which will let the PCM be programmed to have the cruise control functions as the SSR didn't use a BCM.
I have an 06 GTO LS2 in my conversion.. I went with the Gen III or Blue Green PCM part number 12586243 as I wanted to use the DBW for cruise and this was the best way to achieve.
The other reason I used this PCM vs. red blue 411, as this PCM can be used to retain cruise function as well but you must switch to the LS1 style knock sensors, was that I wanted to retain the GTO stock knock sensors...

This required multiple tunes and test drives so if this is not your desired path then stick with the LS1 style.
It was more work but the LS2 style is a lower profile and fit better than the LS1 style sensors for my application.
I hope this helps.
Actually I ended up keeping the LS2 knock sensors but had to fool around desensitizing them in the tune as they did not function correctly.
