Lingenfelter Delivered Torque Output Limiter Trailblazer SS H3 Hummer
Part Number: pwm-001
DTOL Limiter
As one of the first companies to install a supercharger on a Chevrolet Trailblazer SS, Lingenfelter Performance Engineering 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.
