GSM Overview

LS3:

Uses "Rectangular" ports (wide and short). These are designed for maximum airflow at high RPMs. 2. Reluctor Wheel Count Early LS1/LS2: Often use a 24x reluctor wheel. Late LS2/LS3: Usually use a 58x reluctor wheel.

Before we dive into wiring and torque converters, let's define the players. gsm ls1 ak ls2 ls3

1. AK Series Controllers (AEM Infinity): Some users abbreviate AEM's "AK" (AEM Kiln) or mistake the Infinity "AK" series. AEM’s Infinity ECU (models like 5060) are standalone ECUs that support both 24x (LS1/LS2) and 58x (LS3) reluctor patterns. If you are wiring a GSM tracker to an AEM Infinity-equipped LS engine, you must use the "Aux Out" functions to trigger remote start.
2. AK as in "AK-47" (Theft Deterrence): A crude but common internet slang: "GSM LS1 AK" could imply a vehicle build where the GSM alarm is backed up by... physical deterrence. We do not recommend this in a serious technical article, but it appears in forums.
3. AK = "Auto Kill" – Many GSM alarms feature an "Auto Kill" or "AK" relay mode that shuts down the engine when the GSM signal is lost or a theft alert triggers. Wiring an AK relay into the LS1’s fuel pump circuit (grey wire at the PCM) is standard practice.
