These are the relevant data fields from the .JCP field mapping doc:

Somewhere on one of my hard drives I have images of PDFs that show the Equibase data collection points of call for different distances as they relate to timing of the race leader and determining position and beaten lengths for each horse.
I'll post a link to those and make any corrections to what I've posted below - provided I can dig them up.
EDIT--
Here's a link to an older thread that has the two charts for points of call: http://www.jcapper.com/messageboard/TopicReader.asp?topic=2004&forum=GeneralThe first chart is labeled Fractional Times and shows the points of call that Equibase used at one time for timing the race leader for purposes of disseminating sectional times to their licensed data resellers. Note that I said used at one time.In looking at the actual data transmitted to both HDW and Brisnet I've noticed that the chart itself is accurate up to distances less than 10f only. In actual practice, at distances of 10f to 13.5f fraction one and fraction two are the same as those shown on the chart for distances of 14f to 14.5f. This means that for distances of 10f to 14.5f: Fraction one is at 6f and fraction two is at 8f. The second chart is labeled Points of Call and shows the points of call in the race that Equibase uses for generating position and beaten lengths for each horse. Note that for some of the race distances the points of call in this second chart that Equibase uses for determining the position and beaten lengths of each horse are different from the points of call in the first chart that Equibase uses for timing the race leader. The info model described by these two charts is what figure makers rely on when they make speed and pace figs. More on that below in the section about race distances of 5f to 5.5f.

I did this from memory but I think it's right for most distances... here goes:
For distances under 10f --
E1 or first fraction pace figs for past running lines are in fields 766-775... with 766 being the most recent race... 767 the 2nd race back... and 768 the 3rd race back, etc.
E2 or second fraction pace figs for past running lines are in fields 776-785... with 776 being the most recent race... 777 the 2nd race back... and 778 the 3rd race back, etc.
Late pace or final fraction pace figs for past running lines are in fields 816-825... with 816 being the most recent race... 817 the 2nd race back... and 818 the 3rd race back, etc.
For short sprint distances of 3.5f to 4.5f:
E2's and Late's usually not reported because there are only two calls... a pace call at 2f and a final time call at the wire. Normally you'll see E1's in fields 766-775 and final time speed figs in fields 846-855.
For 5f to 5.5f races:
The points of call for position and beaten lengths (which in turn are used to make pace figs) are unique in that the first call is at the 3/16th's pole or 1.5f from the start -- and the second call is at the 3/8th's pole or 3f from the start.
This differs from most other distances where the points of call for timing of the race leader are the same as the points of call for position and beaten lengths (2f and 4f respectively.)
If you give this some thought it means that E1 and E2 pace figs made by figure makers everywhere are estimates - because the actual points of call used by Equibase for timing the race leader at distances of 5f to 5.5f are different from the points of call used by Equibase for position and beaten lengths.
That said, for 5f to 5.5f races the E1's are in fields 766-775 and the E2's are in fields 776-785.
For distances 10f and longer --
The E1's are in fields 786-795
The E2's are in fields 796-805
And the Late's are in 816-825.
I hope I managed to type most of that out in a way that makes sense.
