You Decide When the Torque Converter Locks or Unlocks for Maximum Control!
Command the torque converter to stay locked, stay unlocked, or revert to OEM settings with the BD TorqLoc. Flip the toggle switch to  position one, and the lock-up clutch is engaged, so transmission temperature remains low and the exhaust brake can work with 100% effectiveness (this is a manual setting and should only be selected under light load/light power conditions, such as highway driving).

Position two reverts back to stock function, or can be wired to unlock the torque converter. Position three acts as an AutoLoc by commanding lock-up only when the exhaust brake is engaged - perfect setting for every day driving in all situations.

Additionally, the TorqLoc has an Overdrive “inverter” option which allows the transmission to start out in Drive which will prevent upshift into the Overdrive gear - great for those who live in city/urban areas.  Also, if you have a BD Valve Body with the second gear lock-up capability, the lock-up can be set to hold until 5-10 mph.

AutoLoc Convertor Controls

The BD AutoLoc is a computer that commands the torque convertor lock-up clutch to stay applied when an exhaust brake is engaged.

The AutoLoc ensures that 100% of the retarding force is being transferred in 3rd and 4th gears, thus, transmission oil temperatures remain low because convertor slippage no longer occurs in these gears. The lock-up clutch and brake automatically disengage at low speeds to prevent stalling and transmission and convertor damage.

The convertor lock up clutch applies with accelerator pedal pressure, and the AutoLoc captures this signal. After shifting out or into overdrive in Dodge trucks, apply heavy accelerator pedal pressure or quickly release the pedal and the lock up clutch will engage. Exhaust brakes cause high automatic fluid temperatures due to the torque converter slippage and without a AutoLoc only 10-80% of the retarding force is transferred through the (unlocked) fluid coupling of a torque convertor.

You can drive the truck with the AutoLoc engaged all the time. If you experience a shutter when you slow down in over drive with the AutoLoc engaged, you need to have the AutoLoc reset to disengage at a higher vehicle speed. However, variances occur due to rear ratios and tire sizes.

BD Diesel Power Pod BD Power Distribution Box
This little BD power unit helps tidy up wiring nightmares, allowing for one power source for all your accessories rather than multiple taps into the vehicle's wiring harness. Establish a switched power source for up to 8 optional electronic loads, stereos, electrical control boxes. 40 Amp total load - 5 Amp circuits; 4 switched / 4 constant.

The Power Pod allows you to establish a power source for up to eight optional electronic loads (four switched, four constant) such as stereos, lights, electronic control boxes, GPS and CB radios. The total load is rated at 40 amps with each circuit fused at five amps (fuses included). Each fuse is lit with an LED to let you know if it's good or blown, making diagnostics a breeze.

Cool Down Timer

Turning off an above-idle temperature hot engine after a hard run or heavy load towing can be detrimental to many engine components including turbo bearings.

With the engine stopped there is no oil flow over the bearings that support the hot turbocharger wheel assembly. This causes the residue oil being burned and the resulting carbon will cause premature turbo failure.

You can prevent this from happening with the Cool Down Timer or the Cool Engine Shutdown.
  • Simply set the shutdown temperature, lock the door and walk away. The engine will shutdown at the specified temperature.
  • The Cool Down Timer (CDT) works in conjunction with any K-Type exhaust gas temperature (EGT) probe that is common with most analog pyrometer gauge kits. Wire it to an existing EGT probe or install a new one.
  • The Cool Engine Shutdown (CES) works in conjunction with BD`s own digital gauge package, the X Monitor. The CES connects in line between the X Monitor control module and display and also features an audible alarm to coincide with the X Monitor`s visual alarm settings.

The original X-Tuner has been a favorite with diesel enthusiasts for years—and now BD has introduced its successor: The Ultra X-Tuner. As the name would imply, the Ultra X-Tuner offers even more performance and capabilities than its predecessor. Selectable power gains of 30 hp to 140 hp are possible (depending on application), along with improved fuel economy and better driveability overall.

As with the original X-Tuner, the Ultra X-Tuner simply plugs into the vehicle’s OBD II port, and allows you to read diagnostic codes, recalibrate the speedometer for larger tires, and raise/eliminate the vehicle’s top speed limiter. Plus, you can download the latest calibrations as well as an available data acquisition package from the Internet (most applications). The Ultra X-Tuner is BD’s most advanced programmer yet. Call and order yours today! - Power increase of 30 hp / 50 lbs.ft to 140 hp / 285 lbs.ft
  • Multiple Power Levels - Towing/Performance/Extreme
  • Internet Updateable
  • Easy Installation
  • Improved Fuel Economy
  • Optimized Drivability
  • Diagnostic Trouble Code Reading Capability
  • Enhanced Shift Firmness
