System Description
The GEN3’s ETM system works to control drive shaft speed for an eight (8) second time period using
a patent pending, 32 level torque management control strategy.
What the System Includes and its Capabilities
• An Engine Torque Management Module [not included (not required) with GEN3 coil-on-plug
systems].
• The ETM Harness.
• Imbedded control software to control engine torque.
• The following user defined, system control and configuration tables, located in the main tool bar
under “Torque Management”:
• A “Three-Shooter” timing retard control system. This feature helps control engine torque during
the critical period between the vehicle launch, through the one-two gear shift. *Note: May not be
implemented in all firmware. A six-shooter and twelve shooter retard system is available as an
option. Call BigStuff3 for details.
• An integrated two-step and optional three-step rev limit controller. The system never misfires the
same cylinder two times consecutively, resulting in more uniform EGT’s and higher boost while
staging.
• Extended Data Acquisition “Replay” parameters (described in more detail below) to capture the
following events:
o A Misfire Flag to indicate where in time the ETM system was active (MisFire).
o A Misfire Counter to count the total number of mis-fire events during the eight (8) second
run (MisfireCtr).
o Torque Reduction Stage indicator (TorqRdStg).
o TISS Speed – Displays the desired driveshaft RPM.
o TOSS Speed – Displays the actual driveshaft RPM.
Note: With the ETM functionality the “Replay Mode” is now “Extended Mode”, which means
there are an additional 12 variables/flags that are now part of the Replay for the traction control.
