The D2A was originally designed to decode J216 SENT digital throttle position signals and convert them to the equivalent analog signals. Since then, we have added multi functionality as described below. The D2A enables a wide variety of electronic throttle swaps and enhancement of throttle response.


Digital to Analog- Use a newer style GM drive by wire digital TPS signal (SENT) throttle body with an engine control module designed to control an analog (0-5V) TPS output drive by wire throttle body. Or provide dual 0-5V TPS signals to another device that requires analog inputs. Our D2A module decodes the digital signal and outputs the 2 equivalent 0-5V analog signals.


Analog to Digital- Use an analog output throttle body with an engine control module designed for a digital TPS input. e.g LS3 to LT1, LT4 or LT5

Analog to Analog- Scale and/or invert the TPS signals of an analog throttle body to emulate a different type of analog throttle body.

Enhance Throttle Response- Throttle response can be enhanced and/or scaled in all 3 modes.

Outputs can be scaled to match those of any 0-5V TPS signal throttle body.
