Sensor Input Improvements
Sensor inputs are critical to a transmission controller, allowing it to function and make correct decisions. This particular area has also seen many improvements with new options for throttle position sensors, output shaft speed sensors, and input shaft speed sensors to provide better versatility, diagnostics, and control. The new auto-detect option for Ford range sensors also simplifies configuration and setup.
Negative slope TPS support *
For a wider array of TPS selections, and for compatibility with unique applications, a “descending” TPS signal (one that approaches 5.0V at closed-throttle with a voltage that drops lower as the throttle is opened towards WOT) can be used.
More output shaft speed sensor options
Supporting virtually all different types and versions of sensors. Chances are that no matter what speed sensor you have, it's compatible.
Improved speed sensor circuitry
Improved input signal processing increases accuracy and consistency for speed sensor inputs.
Optional tachometer input for precise shift point control and slip detection
If desired, the new tachometer input can be connected to enhance accuracy of the full-throttle shift points and enable transmission slip detection. The tachometer input is configurable to work with almost any engine.
Input Shaft (turbine) speed sensor utilization (when available) for more accurate control and diagnostics
Most transmissions that include an input shaft speed sensor can benefit from the controller's ability to read and interpret input shaft speed for more accurate control and monitoring. The benefits of using an input shaft speed sensor include the ability to detect transmission slip when the torque converter clutch is not fully engaged, more accurate determination of shift (and TCC) response and completion timing, the ability to discern transmission slip from torque converter slip, and better redundancy if another speed sensor happens to fail. These benefits add up to more accurate shift control, better transmission protection, and enhanced diagnostic capabilities.
All 4L80E transmissions have compatible input shaft (turbine) speed sensors. Most 2004 and later 4R70W and 4R75 transmissions also include a compatible input shaft speed sensor.
Auto range sensor type detection for Ford applications
To simplify initial setup, this feature eliminates one piece of critical information that must be manually entered into the controller's tuning software. Analog and digital range sensors are both supported by this feature and will work seamlessly.
