Turbota's Mod Map 33 revised Scott is talking about is missing
from the location Rico posted. Regardless, one can easily modify
any one of Turbota's Map for DIY testing.

In my first post in this thread I already included the same link (ENT Racing) that Rico reposted.

Hmm. Since it looks like nobody is gonna step up to the podium I'll answer.
Everyone who is doing their own now started out using Turbota's Maps as a starting point and from there
it was trial and error. As far as my developments, I'm finding that Buzzelli's guidelines are close.
If I go one way or the other too much I can look
at my spark plugs and confirm that something isn't right in addition to feeling it in the performance
of the motorcycle. I also feel quite strongly about
the fact that in order to get it as close as possible,
one must be able to test ride the bike they are mapping
after each tweak.

Generation? There isn't any. There are lots of folks who have written their own Maps
who have pm'd me and told me so but they don't wish to be known because they're
afraid people will ask them for maps.
Trial and error changing values in cells and uploading to the same module that
Turbota used. Same concept. Different numbers. After awhile there are only so
many timing curves that are gonna prove to work the best in a given bike. Finding that out
is not difficult, it's just time consuming. (edit, upload, test ride) Don't let people make
ya think it's rocket science because it's not. And as Lenster said, don't be afraid to
change the values to get a feel for how the bike responds.

I see. Well yes people might want to put labels
on it but the fact remains that the module and
the software and the process to program it is
the exact same now as it was when Turbota brought
it to us.
You can write your own Map and call it whatever
you wish, but the tools and the way you get
there is the same whether you program it or
someone else does so imo there is no 1st or 3rd
gen. To most that implies the hardware and or
software is new which is not the case at all.

Also keep in mind that many of us are writing our
own, which is the basis of this thread. If you
are interested in writing/loading your own you just need
the module, the software, the cable, and a Windows based computer.
As noted earlier in this thread I'm running what I've
dubbed the "Black Panther" Map. It's just another Map in addition
to the many Maps that lots of other people have written. I am really not interested
in writing Maps for others, but rather in learning and sharing
with folks who want to or are currently doing the same.
Sorry for the long winded reply, I'd just rather not confuse
people with that gen. stuff in this particular thread because
from a technical standpoint it really doesn't apply at all.

Yup there are def certain areas where some bikes require more timing than the tc88a is capable of programming, and if you look at a graph out of a newer bike you will see it. If there was a way to pull the stock timing table from the carb'd bikes I think many of the folk who think they know what's up might be surprised.

None of the DiY people have anything new to add to the convo? Shame since there are quite a few who don't wanna be spoon fed.

I'm still mapping Xena. Mine are derived from the switch settings and I'm still messing with the EX maps I was messing with last winter. I'll send ya a copy of my latest creation for your viewing pleasure if you like. I doubt it would work well in your bike but it works great in mine.

beat my head on the wall about this....

i believe you have this backwards. 30 in/hg is sea level and the lower the number the more vacuum you have

if the throttle is all the way open the MAP sensor is exposed to atmosphere while if its closed the engine is trying to suck through a much smaller hole creating a vaccum.

hope that helps

That is correct. The farther closed the throttle is, the higher the vacuum. As the vacuum increases, the timing must increase proportionately.
