Mechman® ChargeCommand IQ™ RVC — Take Control of Your GM Charging System
Boost and optimize the alternator charging voltage of your 2005-2026 GM™ car, truck, or SUV. (See application guide) Maximize your electrical system for car audio, stereo, winching, off-road, racing, & van camping applications. This easy to install voltage regulator allows the alternator charging voltage to be adjusted up or down for most 12 volt lithium, AGM or lead-acid batteries. This smart enabled device prevents the vehicle's computer from lowering charging voltage - giving you more stable battery charging performance. The built in LCD screen displays voltage set point, actual battery voltage, and alternator duty cycle, giving the user a clear view of charging system function.
⚠ Check your plug before ordering
Only compatible with GM™ RVC-controlled alternators that use the 2-pin regulator plug. Remove the factory harness plug and verify the connector style directly at the alternator's regulator before ordering.
Vehicle year, make, model and engine are a general guide. Not every vehicle in those years uses this plug. See the GM™ RVC Application Guide below ↓
Many GM™ vehicles use Regulated Voltage Control (RVC), where the engine computer lowers the alternator's charging voltage for a tiny increase in fuel economy. Most people prefer to maintain a higher charging voltage for optimized electrical accessory performance in exchange for an immeasurable difference in fuel economy. This increased voltage set point boosts the charging system performance of both OEM equipped alternators and Mechman® High Output Alternators.
ChargeCommand IQ™ RVC puts charging control back in your hands.
Designed for seamless integration with the factory engine computer, ChargeCommand IQ™ RVC connects at the alternator's 2-pin RVC plug and allows you to adjust the charging voltage set-point of the alternator, while removing factory amperage limitations that can prevent the alternator from delivering its full potential.
A built-in screen displays your charging voltage set-point and battery voltage at a glance, and the push buttons on the unit let you adjust the set-point.
Installation is quick and straightforward. The ChargeCommand IQ™ RVC module plugs in between the alternator and the alternator harness plug and retains all original battery light function. Simply locate and connect any ignition switched 12v wire to the module's harness, and ground the module's ground wire to battery negative and you're good-to-go! Factory battery warning lights and OE voltage gauges continue to operate normally, giving you improved charging control without sacrificing the functionality built into the vehicle.
