Sportsterpedia Progress

[60Gunner]

I can add that Rico's scarecrow map would be for a similar build as mine. The biggest difference being mine has more low map/low rpm advance.
A good, safe map to start for 1250/1275 builds.
Moscow is a little more conservative and the Jester maps more agressive with Jester V the least agressive. Most of these are better suited for more stock motors tho a few have used Jester V on a 1250 with cams I believe.
Hopefully this helps some.

Great work on the Sportsterpedia guys. The wealth of information is very impressive and more is added continualy. Thank you for the tireless work, i certainly appreciate all the efforts.
PS, is there any way i can easily transfer/convert the timing maps to EFI? Any thoughts are welcome.

Thanks for the positive comments - We're always looking for ways to improve - so keep looking and give us some suggestions as appropriate - Not that we don't have enough work to do already... (Right, Hippysmack??)

As to conversion to EFI - The information in the TBL files provide requested timing settings relative to MAP conditions (Manifold Aboslute Pressure readings) - I would think that is convertible to later EFI mapping - Each change in the ignition systems (over the years) has brought greater resolution (control in very small increments) to the tuning process... Which means the later models consider more in determining exactly what timing should be active and it is able to control that in very small changes...

In converting values, remember that MAP values are the inverse of Vacuum values:


But I don't have a later bike, so maybe I'm missing something...

Of course, you have to consider that every bike that gets upgraded has its own particular needs (heck, even stock bikes differ in what they like tuning wise due to location, weather, etc.) --- So, getting in the ballpark is usually the first step and then careful tuning toward your specific needs...

The values in the TC88A MAP columns (I believe are in inches of mercury) don't exactly match the values the kPa values in the EFI spark tables and do not go into the 40 kPa and under columns but you can use these approximate values to convert.

30 Inches of mercury = 101.5 Kilopascals
28 Inches of mercury = 94.8 Kilopascals
26 Inches of mercury = 88.0 Kilopascals
24 Inches of mercury = 81.2 Kilopascals
22 Inches of mercury = 74.5 Kilopascals
20 Inches of mercury = 67.7 Kilopascals
18 Inches of mercury = 60.9 Kilopascals
16 Inches of mercury = 54.1 Kilopascals

I would probably use 54 kPa value in the 40, 30 and 20 kPa columns for EFI.

And thank you for the kind words.
We don't have data for that to date.
As always, tuning changes can bring on good or bad results.
I haven't run across any research yet for converting but this forum is huge.
So it may be buried here somewhere.
If anybody can point us to that information, we'll put it on the list.

Hahahaha.

Our plates are always full.
As such, we can never go hungry.

I'll second that, and i'm sure plenty more on here will do so as well.

Thank you.
And thanks to everyone who contributes to this forum.
No better place to be.

Thanks Shanneba for the information. I can work with this. Ride Safe.

[Bikeaholic]

To Hippy. Ha ha. Yes your plate is very full. I was not wanting to add to your work load. Just a general enquirey while i was on the thread. Ride Safe.
