Lingenfelter Trailblazer SS Delivered Torque Output Limiter
As one of the first companies to install a supercharger on a Chevrolet Trailblazer SS, Lingenfelter Performance Engineering (LPE) learned early on about some of the difficulties involved in doing so. One of the problems that we found when we ran the supercharger at higher speeds and boost levels was that the stability control system (Stabilitrac) would become disabled at fairly low throttle angles. Our testing on a boosted Hummer H3 encountered similar results. This device was developed by LPE to solve those problems.
On the 2006-2007 Trailblazer SS, the 2006-2007 Hummer H3 and several other GM vehicles, the ECM sends a delivered torque signal to the EBCM or EBTCM. If the output from the ECM exceeds the expected value, the EBTCM will disable Stability Control and will cause a warning message to display on the dash. High output engine upgrades, especially superchargers and turbochargers, can cause this to occur.
This device is designed to allow you to limit the delivered torque signal received by the EBTCM and solve this problem. This allows the stability control system to continue to function at these higher power levels and eliminates the annoying warning message on the dash.
This device will only work on vehicles that have a discreet delivered torque signal between the ECM and the EBTCM. On some vehicles, like the 2007 full size SUVs and trucks, the delivered torque signal between the ECM and the EBTCM is a part of the serial data communication signal between the ECM and the EBTCM. This device will not work in those types of applications.
The Lingenfelter Delivered Torque Limiter module includes a diagnostic LED to confirm proper operation. Compact design is fully potted for added durability. The Delivered Torque Limiter also has a Pass Thru setting, allowing you to disable the device and return to stock operation if you should need to do so.
Easy to install - only four wires - one for power, one for ground and then the other two intercept the delivered torque output signal from the ECM. You can either cut the delivered torque wire and install this device in between or you can back the pins out at the underhood fuse block and connect at that point. Installation instructions for the Trailblazer SS and Hummer H3 are included. |
