Procom Fuel Injection Electronic Control Units: Precision Tuning for Powersports

Procom Engineering is a California-based manufacturer with a focused mission: giving powersports riders and builders the electronic control they need to unlock real performance gains. Within the Fuel Injection Electronic Control Unit category, Procom stands apart by offering both direct-replacement programmable ECUs and innovative fuel mapping controllers — purpose-built for ATVs, UTVs, motorcycles, and other powersports vehicles where the stock ECU simply cannot be reprogrammed to match a modified setup.

Why Stock ECUs Hold You Back

Modern fuel-injected powersports engines are factory-tuned for emissions compliance and broad consumer use, not for maximum output. Stock ECU maps often run lean, which is acceptable under everyday conditions but becomes a limiting factor the moment you add a performance exhaust, an air intake upgrade, or change elevation. Stock modules can be hard or even impossible to reprogram, and Procom Engineering addresses this limitation head-on with a lineup of programmable electronic control units and performance CDI modules.

Procom's ECU Product Lines

Procom's programmable ECU lineup includes units like the PE-E-AY700R-A for the Yamaha Rhino 700, featuring a timing curve optimized for maximum performance, modern circuitry for improved spark energy, and a simple plug-in installation. These replacement ECUs are designed to drop straight into the factory location, eliminating the need for custom wiring harnesses or complex modifications.

Alongside their replacement ECUs, Procom offers the PowerJet Fuel Controller — a clever device for riders who want fuel map adjustability without swapping the entire ECU. The PowerJet allows adjustment of the fuel map from -4% to +10% across seven selectable settings, including a stock setting that leaves fueling completely unchanged. The PowerJet works by measuring outside air temperature near the OEM sensor and adjusting the signal sent to the ECU, exploiting the stock ECU's built-in Air Temperature Correction factor to prompt the engine to inject more fuel as needed. This approach is elegant in its simplicity: no reflashing, no laptop required.

Plug-and-Play Performance with Warranty Backing

Installed in place of the stock unit, an aftermarket Procom ECU gives the rider full control over fuel supply and ignition timing. Procom keeps installation accessible by engineering all of their ECU and fuel controller products as direct plug-in replacements — a critical advantage for riders who want measurable gains without a trip to the dyno shop. All Procom performance parts carry a limited twelve-month warranty against defects in workmanship and materials, provided to the original purchaser.

Who Should Consider a Procom ECU or Fuel Controller?

• Riders running aftermarket exhausts who are experiencing lean-running symptoms or flat spots in throttle response
• ATV and UTV owners who have modified their air intake or engine internals and need fuel map correction
• Track riders who need consistent fueling at wide-open throttle
• Powersports enthusiasts who want a reversible, non-invasive fuel tuning solution

Whether you need a full ECU replacement with reprogrammable timing curves or a straightforward plug-in fuel controller to compensate for bolt-on modifications, Procom's Fuel Injection Electronic Control Unit solutions offer a well-engineered path to better performance.
