 PCM MODULe

General Information

Many newer vehicles have “smart charging systems” which control alternator voltage setpoint to save fuel and increase certain performance characteristics of the vehicle in varying conditions. Our PCM voltage control module will give the user complete control of the voltage setpoint while retaining OEM integration on PCM controlled charging systems. Our module can either be programmed to a fixed voltage or allow for adjustable voltage while maintaining battery light function. It also allows the retrofit of PCM regulators on older cars to dial in on the exact desired voltage. Designed for in-cabin or under-hood applications, the US Alternators PCM module is an easy install solution for most Ford, Lincoln, GM, Chevrolet, Buick, Cadillac, Infiniti, Nissan, Hyundai, Kia, and Subaru vehicles. Modules for some Honda, Toyota, Mazda, Lexus, Mitsubishi, and Scion vehicles will be released in the future.
