I'd love to see a timing map for the early 5.7 if you are willing to share. My understanding is the factory ECU had two maps, one for normal driving and one for WOT. Like you, I have the old school aluminum case MS3X. I actually built it too. Pretty sure my eyes wouldn't allow me to do all that board level soldering these days... I've considered upgrading to their newest products, but I don't have a valid reason to do so. I do however, want more inputs so I can install a 3 axis G meter.
