Introduction to Torque Management
Torque Management is a feature in modern GM trucks that limits engine power to protect the drivetrain. This thread delves into how Torque Management affects vehicle performance through detailed data analysis using AutoTAP.
Data Analysis with AutoTAP
The author used AutoTAP to pull data related to Torque Management, revealing how the system affects ignition timing and throttle control. The data shows significant changes in timing and throttle position during wide-open throttle (WOT) runs and speed limiter engagement.
Impact on Ignition Timing
During WOT runs, ignition timing is pulled back significantly, leading to reduced power output. For example, timing is pulled WAY back from a stop and remains negative until positive timing is finally achieved. This results in a noticeable power loss during acceleration.
Impact on Throttle Control
Torque Management also affects throttle control, limiting the throttle blade position even when the pedal is floored. This is evident in the data showing the PCM requesting a throttle position of 58% at 94-99 MPH, despite the driver’s input.
Community Responses
The thread sparked discussions about the reasons behind Torque Management. Some users suggested it is to reduce wear and tear on the drivetrain, while others pointed out that modern transmissions are built better and do not need such extensive management. There was also a mention of the EPA rules as a potential reason.
Alternatives to Torque Management
Several companies offer custom tunes to remove or reduce Torque Management, such as Westers, Nelson, Predator Programmers, and SPE ProFlash Programmers. These tunes can improve vehicle responsiveness and performance.
