Definitely enjoyed it. It sounds like you have to go to a 2-week crash course on LS Theory of Operation to understand fully how each component affects others. You mentioned RU-vid. I haven't looked yet and I'm not going to be making any PCM changes for some time, but would you say that the resources to understand how what you are doing in one place impacts other areas can be found on RU-vid? Probably a dumb question. I have a friend who has HP Tuners and has offered to help me when the time is right. He is a huge fan of turbocharging and has several wicked VW's and Audi's. He also loves doing VR6 swaps on VW's. I am thankful for the "tune your LS in a nutshell" overview. It is pretty amazing what they (GM) have done with this and now I can see why it is such a popular swap. I used to think that the LS was just a better small block Chevy, but it is really more like a gearhead's sandbox/playground!
🤔😂took me three try’s to get through this, I’m still not really comfortable with the laptop thing! I realize this is a boosted issue, but in my early life, many of us started with flathead motors! Tuning started with the Small Block Chevy and Ford OHV motors, a Posi diff, gears, a handful of mechanical advance weights and springs, some carb jets, metering needles, cams, a vacuum gauge, timing light, stopwatch and a measured distance! Pings, lighter weights, or heavier springs, idles Ok, road test, adjust. Repeat as many times as necessary to get to where you wanted to be. Oh ya don’t forget the revelation that struck while you were in the shower, or while you were asleep, that gave you something to try the next Friday night! This is probably an over simplification, but those were my recollections! Still have the vacuum gauge and Timing light, but there’s no requirement for them anymore! Thanks for sharing your process!
I'm old enough to be very good at carb tuning and ignition re-curving. I wanted to specialize in tuning back in the day. Tuning like that is long gone. If you can tune a carb, you can tune EFI. And instead of nailing idle and WOT and hoping everything inbetween works, you get pinpoint precision for each and every operating condition. It really cool, AND you don't have to smell like gasoline. When I teach kiddies fuel systems, I teach carbs first using EFI terms, and then it's easier to teach EFI because we already use the terms.
