Precision Turbo and Engine BigStuff3 GEN3 Engine Torque Management (ETM) System - Manual (Page 7)

Torque Reduction Stage
nine (9) means the GEN3 ECU will apply a
very aggressive timing control strategy in an
attempt to bring the actual drive shaft speed
in line with the user defined, desired
driveshaft speed. Note that the drive shaft
“error” equals 896 RPM.
A Torque Reduction Stage of twenty eight (28)
means the GEN3 ECU will apply a minimally
aggressive timing control strategy in an attempt
to bring the actual drive shaft speed in line with
the user defined, desired driveshaft speed.
Note that the drive shaft “error” equals only
128 RPM.
“Driveshaft RPM Error” is
defined as the difference
“error” between the desired
driveshaft speed (TISS) and
actual drive shaft speed
(TOSS).
Misfire Configuration
The TC Parameters table allows the user to define the maximum number of misfire events during the
eight (8) second run. Note: Currently not used.
Torque Control (enable/disable)
Traction Enable: When this box is checked, the torque management system is activated. It is advised
not to enable this until a good “Desired Driveshaft Speed” curve is determined. It is best to verify this
with a Replay first before activating it.
