Description

The LT-Master Kit includes everything needed to bench flash, read, write, and recover supported LT1 PCMs.
The included OBD Benchbox comes with a 5-amp power supply, LT1 PCM connectors, OBD port, and Molex-style connector for one side of the case. It is designed to make bench flashing simple and can also be adapted to other PCM connectors if needed.

LT-FLASHv2 is a 1996–1997 OBD-II flash tool used to read and write the PCM. Calibration editing is performed with TunerPro using the supplied XDF files available in the software downloads section.

LT-FLASHv2 now includes dual 0–5V analog inputs, which can be used for wideband oxygen sensors or other compatible 0–5V sensor signals while logging.

LT-UNBRICK currently supports 1994–1997 PCMs and is used to recover a PCM after a failed write. In the tuning community, this is commonly known as a “brick.” A failed write can stop all bus communication and make the PCM unusable. LT-UNBRICK allows the PCM to be repaired by installing headers on the PCM circuit board and writing the files back directly to the PCM. This process requires PCM disassembly and is explained in the downloaded instruction manual.

The package includes the LT-FLASHv2 module, LT-UNBRICK module, USB cable, DB9-to-OBD-II cable, ribbon cable, two headers, CPU reset tab, and LT-UNBRICK instruction manuals for download.
