Note this repo is still in BETA stage, so there might be some glitches and not everything is working as planned yet! Further, other than with our F-Droid repo, there is no extensive scanning framework in place. Modules are taken in directly from their resp. developers.

It's crucial to distinguish between the and the Tech 2 . The Tech 2 was the factory scan tool for GM vehicles from about 1992 to 2013. For the vehicles this tool covers, there is an official emulator.
Emulators often allow you to log engine data during test drives, which is invaluable for diagnosing intermittent issues. Components of a Tech 1 Emulator Setup
However, as original Tech 1 units and their model-specific cartridges become increasingly rare and expensive, maintaining these vintage vehicles (like C4 Corvettes, early Camaros, and GMT400 trucks) requires modern solutions. Enter the . What is a GM Tech 1 Emulator? gm tech 1 emulator
Perform the mandatory automated bleed procedures required to clear air bubbles out of the ABS modulator valve blocks (critical for 1990s Corvettes, Camaros, and trucks). 3. Body Control and Comfort Systems Diagnose Electronic Climate Control (ECC) faults.
At the center, a stylized, glowing outline of a car engine takes prominence, representing the heart of automotive technology. Superimposed over the engine are circuit lines and microchip patterns that glow softly, indicating the integration of modern electronics and computing.

Widely used by owners of classic GM, BMW, Ford, and Porsche vehicles. 2. TunerPro / TunerPro RT
There are two primary types of emulators on the market: Emulators often allow you to log engine data
The primary function of a Tech 1 Emulator is to replicate the hardware environment of the original Mass Storage Cartridge (MSC) and the handheld unit itself on a modern computer. During the late 1980s and early 1990s, GM vehicles used a proprietary 12-pin Assembly Line Diagnostic Link (ALDL) connector. Unlike modern scanners that provide generic codes, the Tech 1 was capable of bidirectional control—allowing users to cycle fuel pumps, adjust idle speeds, and reset ABS modules. An emulator restores these capabilities by translating the high-speed data streams from the vehicle’s Electronic Control Module (ECM) into a format that a Windows or Linux-based PC can interpret.
Turn the vehicle's ignition key to the position (engine off) or start the engine, depending on what type of diagnosis you are running. Step 4: Run the Simulation
