INSTALLATION INSTRUCTIONS
PROGRAMMABLE FEATURES
Application
The number of cylinders and number of gears must be programmed. The Cylinder Count (CylCnt)
default is 8-cylinders, and can be programmed for 4 or 6-cylinders. The Transmission needs to
be configured as well. The default is 6-gears and can be programmed for 2, 3, 4, 5 and 6-gear
transmissions on the (LastGear) menu.
Gear Solenoids
There are different shift solenoids available and will need to be selected. The default is a Sequence-
On which is activated with 12 volts and remains on. There is also a Pulsed solenoid that receives a
Pulsed signal to activate the solenoid. The time of the Pulse signal is also adjustable from 0.100 to
2.5 seconds in 0.010 increments (The solenoid manufacturer should specify a pulse time).
Shift RPM
The rpm for each gear change needs to be programmed from the Gear Select (GearSel) menu. The
rpm can be programmed from 1,000 to 12,500 rpm in 100 rpm increments.
Launch Wire Activation
This program (LaunchIn) selects the input signal. The Dark Blue wire is the Set/Reset wire and can
be activated by either being grounded or when connected to 12 volts. The default is the ground
setting.
Note:
To test the Dark Blue wire's operation, the engine must be running so the Shift Controller
receives a trigger signal. MSD offers an optional tester, PN 8998, that allows you to test the
Controller without the engine running. See page 6.
Shift Inhibit
This program is programmable from 300 to 600 milliseconds. It will inhibit or delay the next shift from
occurring by the amount of time programmed. This (Inhibit) is used during the launch or in cases of
wheel spin. The default is 300 milliseconds.
