Tuning the Monster...I hope

[KennyChapman]

First of all, thanks everyone for being so cool and helpful! So I guess I did my project backwards. As an oldschool car guy I built the motor for my 1999 c2500 Suburban first and then hoped it would run on it's original "black box" ECU. The engine is a 496 stroker BBC With custom intake and heads. OEM injectors on a not so OEM fuel system. Anyhow, It looks like my best bet for this thing is to do the Ol' 0411 swap. I already PM'd Lextech, but would love any help that can be offered with a base tune or at least a starting point for one. I am on overload with all the data that is here and it seems that there is little about this particular build of mine. At least I can't seem to find it when searching the forum. I ordered and received a GT dongle from OBDXpro last week and hope to use PCMhammer and Tuner pro for this tuning. Thanks in advance for any help you can send my way.

Thanks for the Welcome! So, progress report. I made it out to the local "you pull it" Junkyard today and picked out two 12200411 PCMs with connectors (In case I ruin one) for $40. I cleaned the gunk off the outside of them and soldered up a bench harness. After some fooling around with drivers and rebooting my PC I got the OBDXpro GT to finally work and was able to save my first BIN file, which I am attaching, in case anyone cares. Now on to find an XDF for it...
