parameter 16100 (FuelSense®) is set to 60, and parameter 12010 (Level of Acceleration Control)
is set to 0 (Custom).
NOTE: Paragraphs 8 through 12 only apply when selecting a value less than or equal to 16 for parameter
11020 Engine Make & Model. If 11020 value is greater than 16, skip to paragraph 13.
8. 17900 DynActive: Engine Torque Curve (1000/2000/3000/4000): The DynActiveTM Shifting algorithm uses
the engine’s torque curve to calculate an optimum fuel economy shift profile. Use parameter 17900 to select
whether the DynActiveTM Shifting algorithm learns the engine torque curve, or whether the specific engine
torque curve will be manually entered. Parameters 17901 – 17920 and 17941 – 17960 are used to define the
engine torque curve manually, as described below.
0 = Learned (Default)
1 = Defined
Action Required: No action necessary. Set parameter 17900 to the desired value. See instructions
for using FuelSense® 2.0 and DynActiveTM Shifting with basic (SEM & LRTP OFF) engines.
9. FuelSense® 2.0 and DynActiveTM Shifting with basic (SEM & LRTP OFF) engines (1000/2000/3000/4000):
When engine make & model is known and selected in the calibration, the transmission control system can
rapidly and efficiently learn the engine’s torque curve. However, when a basic (SEM & LRTP OFF) engine is
used, one of the following two options must be used to provide the TCM with engine torque information if
DynActiveTM Shifing is enabled:
a. Option 1 Engine Torque Curve Defined (preferred): Set parameter 17900 = 1 and manually enter the
engine torque curve by entering between six (6) and twenty (20) engine speed and torque pairs, as
described in following paragraphs 10 and 11 .
b. Option 2 Engine Torque Curve Learned: Set parameter 17900 = 0 and select the appropriate value
(13, 14 or 15), as described in following paragraph 12.

10. 17901 – 17920 DynActive: Defined Engine Curve – Speed Point (RPM) (1000/2000/3000/4000): When
parameter 17900 is set to 1, use parameters 17901 through 17920 in conjunction with parameters 17941
through 17960 to define the engine’s torque curve. A minimum of six (6) torque/speed pairs are required but
up to twenty (20) pairs may be used.
0 = Min
0 = Default
5000 = Max
Action Required: At least six (6) torque/speed pairs must be defined when parameter 17900 is
set to 1. PAR files that do not satisfy this condition will result in an unsuccessful EOL programming
event. Enter speed points in ascending order. Consult with Allison Application Engineering for other
requirements associated with these parameters.
11. 17941 – 17960 DynActive: Defined Engine Curve – Torque Point (N∙m) (1000/2000/3000/4000): When
parameter 17900 is set to 1, use parameters 17941 through 17960 in conjunction with parameters 17901
through 17920 to define the engine’s torque curve. A minimum of six (6) torque/speed pairs are required but
up to twenty (20) pairs may be used.
0 = Min
0 = Default
5000 = Max
Action Required: At least six (6) torque/speed pairs must be defined when parameter 17900 is
set to 1. PAR files that do not satisfy this condition will result in an unsuccessful EOL programming
event. The first torque value pairs with the first speed value, and so on; i.e., parameter 17901 pairs
with 17941, 17902 pairs with 17942, etc. Consult with Allison Application Engineering for other
requirements associated with these parameters.
12. 11020 Engine Make & Model (1000/2000/3000/4000): Three new parameter values were added to parameter
11020 to signify when using an engine that is not listed by name elsewhere on the list of engines. Values
13, 14 and 15 are used when accurate engine torque information is available for use by the DynActiveTM
Shifting algorithm.
13 = SEM & LRTP OFF – Other Engine – Diesel – Peak Learned – Accurate Engine Torque
14 = SEM & LRTP OFF – Other Engine – Diesel – Accurate Engine Torque
15 = SEM & LRTP OFF – Other Engine – Spark Ignited – Accurate Engine Torque
Action Required: Values 13, 14 and 15 require Allison Application Engineering approval to confirm
accurate engine torque information is available to the DynActiveTM Shifting algorithm. Two selections
exist for Diesel engines and another for Spark Ignited engines. Consult with Allison Application
Engineering for engine validation requirements associated with the use of these parameters.

Custom. Units are in Newtonmeters.
0 = Min
0 = Default
3000 = Max
