apparently I screwed myself

I rode my last Fat Boy for 16 years.
If I go that same distance again I'll be pushing 80. I work out a lot for the last 40 years straight, and eat right (mostly). I quit drinking and using drugs almost 30 years ago, and I quit smoking cigarettes 8 years ago.
My health is good so I think I have a good shot at still being alive and kicking at 80, but nothing is certain. Its probably safe to assume I wont be shopping for any brand new Fat Boys for model year 2042
Dave has a long wait time for a reason. I will say that both guys have had my bikes running very well. One is more expensive and puts more time into the tuning process. My more basic builds have gone to Chuck. My more extensive ones go to Dave. Given you dont want to lose out on the riding season, makes sense to use Chuck. If you want it to be all that it can be, wait and go to Dave.
Doesnt even need to be the right cam. Just needs something in there that he can work with.
Hope on the horizon, but it looks like I'll have to wait a few weeks at least. July is friggin hot and I dont ride a lot when its super hot anyway.
I think its not binary, where you either know how to tune or dont know how to tune, and if you know how to tune you can tune anything.
Seems theres a lot of different places in between those two extremes.

I'm a Sr UNIX Systems engineer by profession. I've developed a lot of applications by first taking something that already exists and modifying it to suit my needs,
which is very different than than creating it from scratch. Unless you have something in the ballpark to start with, you're just taking wild guesses at the values you need.
Of course the developers that created the original maps and databases could do it in their sleep, the rest of the world is just starting to crack that code cuz the developers aren't going to share

This is how I'm interpreting what I'm hearing from him. Am I right? who knows

The ECU is a computer, and the ignition timing, air/fuel maps, etc are all stored in tables in a database there somewhere and to modify them you need the right tools and the right skills.
Each generation of the ECU is a different animal (new operating system), and they are still working to crack the Gen 2 ECU
Thats my interpretation, based on limited knowledge

He should be able to go from this. If he needs something more, you can pay FuelMoto for access to their data base to download the map for a Low Rider ST. Here are the specs for that cam.
If he can build it from a map for an aftermarket cam, he should be able to build it from a map for the cam that comes in it or an LRST.
My answer is the same either way. He stated that he doesn't understand why the guy needs a map, and I presented a theory (making it clear that I'm just guessing) based on my experience as an IT systems engineer, which is pretty much the same thing you just said. Saves time from having to come up with it from scratch
