It has both injector offset ($34C1) and pump compensation ($34D3) vs. 
battery voltage tables.  The pump comp table is a multiplier but is all
ones.  The inj offset is in msec and gets added to the calculated ipw:

Volts   Offset, msec
 0.0     7.78, N=E*32.768 so 7.78=$FF
 1.6     7.78
 3.2     7.78
 4.8     7.78
 6.4     7.78
 8.0     3.3
 9.6     2.0
11.2     1.5
12.8     1.07
14.4     0.82
16.0     0.64
17.6     0.46
19.2     0.46
20.8     0.46
22.4     0.46
24.0     0.46
25.5     0.46

In the tech area of www.gnttype.org there is an Excel spreadsheet with
most of the data tables, and a disassembly listing with comments.
