What a great project you completed! Enjoy!!

This is an awesome post! Congratulations on taking a chance and it working out for you. What changes have you made / how'd you get the engine parameters to work going from DI back to port injection? Did you have any ECM / BCM issues if you used a different computer than stock? I have HP Tuners as well, but haven't really made the time to do a deep dive into all the different windows that can be changed.

The factory ECM was a E92 direct injection and the ECM that I ended up having to use was a E78 port injection there was roadblocks in the BCM. We have no way to tune the BCM so I had to pin out the electrical fans. FYI, you cannot use a used ECM unless you have the used ECM unmarried from its original vehicle until the LT BCM software is made available. This will be the major issue for all GM ECM’s 2014+

Thank you for the info. I doubt I'll ever do what you did, but I LOVE the tenacity behind it. I had a 2015 HD with the 6.0L and absolutely loved that motor. It didn't care how it was used / abused. I worked that thing on a daily with 12 - 20k of weight and it rolled with the punches. I treated it like a queen maintenance wise, but didn't care about fuel because it was on a company card. I will say that you can absolutely drive a 6.0L like you STOLE it and still return 9.5 - 11.5 mpg (yours being about half the weight on a regular will be better mpg probably. They like to breathe). One of my most favorite trucks......they don't make them like that anymore.

The L96 in the suburban 3500 is the last of the great LS engines, and it’s one built to work, with no AFM. They’ll probably have to bury me in my suburban someday.
