The Baumannator TCS is a revolutionary device which allows an electronically controlled transmission to be fitted to any vehicle, while providing infinite adjustability of all transmission functions via Microsoft Windows®. The features and specifications of the Baumannator TCS are described in detail within this document. If further questions arise, please feel free to contact Baumann Engineering by telephone at (864) 335-9365 or via Email us from our Contact and Company Info Page.
The Baumannator TCS provides the following specifications and features:
The Baumannator TCS controls shift scheduling, line pressure and torque converter clutch operation, while providing complete tunability of these functions via Microsoft Windows® based tuning software running on a personal computer. A laptop PC can be used for in-vehicle tuning and troubleshooting of the system, or a desktop PC can be used with the optional AC adapter if a laptop PC is unavailable. Any PC capable of running Windows® 3.1 with a minimum of 2MB RAM, 386SX-16 Processor, 3MB of free disk space and an available serial communications port will be capable of running the Baumannator host software. These system requirements allow even "garage-sale" computers to be used with the Baumannator system.
Shift points can be adjusted graphically as a function of load (throttle position), allowing each shift point (1-2, 2-3 and 3-4) to be tuned independently at each load point between closed and wide-open throttle. Upshift and downshift points are independently tunable for each gear at all load points. Overdrive (fourth gear) can be used at full throttle without any difficulty, while the inherent flexibility of the system allows tuning to avoid the constant 3-4 and 4-3 part-throttle shifting ("overdrive hunt") found with most non-electronic transmissions.
The line pressure curve versus load may also be tuned to alter transmission torque capacity and part-throttle shift firmness. Torque converter clutch operation is also adjustable, allowing the minimum and maximum allowable throttle angles as well as cut-in and hold speeds to be set. The Baumannator torque converter clutch strategy does not allow the AODE or 4R70W converter clutch to slip under steady-state conditions, as with the OEM strategies for these transmissions. This provides significantly better converter clutch durability in high performance and heavy duty applications.
There are also other enhanced features which can be wired into the vehicle at the customer’s discretion. These features are not required, but will add a lot of value to the package. If not desired, certain features, such as the ManuTronic function, can be disabled via the PC-based tuning software.
These enhanced function inputs include an alternate table selection input and our new ManuTronic feature. The alternate table input will (with the application of +12 volts to the input) select a secondary lookup table from the calibration memory in the TCS. This allows two calibrations or personalities to be stored in the controller with every parameter independently adjustable. Using the alternate table input, the calibrations can be switched on the fly at any time, allowing operation with an external switch, nitrous oxide system or other 12 volt stimulus to provide selection of the secondary table.
The ManuTronic function allows manual gear selection via the original equipment speed control (cruise control) switches. This feature allows up and down-shifting through all four gears at any time, using the Accel and Coast buttons located on the steering wheel. Initiation of this mode requires pressing the Coast and Off buttons in sequence, allowing it to coexist with the speed control system while being mutually exclusive of it.
The Baumannator TCS may be used to retrofit an electronic transmission to a vehicle which was not originally equipped with one. In a fuel-injected application, the conversion simply requires a few connections into the engine management system for power, ground and throttle position. Carbureted applications require installation of a throttle position sensor to the carburetor throttle linkage, which should prove easier than adapting a TV cable for a Ford AOD or similar non-electronic transmission. All other sensor connections are integral to the transmission harness. Transmission harnesses can be provided in a turn-key manner, if so desired.
It is possible to use the Baumannator TCS in a vehicle which was originally equipped with one of the intended transmissions. This could be done in conjunction with an engine management system upgrade (such as an F-150 Lightning mass air flow conversion or the use of a tunable after-market engine management system) that no longer supports the transmission. Use of the Baumannator for this purpose allows flexibility in choosing the engine management system, in addition to the increased control, performance and transmission durability afforded by the Baumannator TCS.
To accomplish such a conversion, use the wiring diagrams and pin connection tables in the instruction manual in addition to factory wiring diagrams, it is possible to modify the factory wiring harnesses to allow use of the Baumannator TCS with a different engine management system. Baumann Engineering can assist this process by providing additional information or advice when available.
