Ecotrons

What Ecotrons does

Ecotrons (legal entity Ecotrons Tech LLC) is a privately held US electronics manufacturer headquartered at 2942 Columbia St, Torrance, CA, with 11-50 employees. It designs and manufactures Electronic Fuel Injection (EFI) systems for small and special engines (35cc-800cc range, 1-2 cylinder, including UAV engines) and, more recently, supervisory controllers for electrified powertrains. The technology stack is built on scalable NXP/Freescale microcontrollers (plus Infineon TriCore and ST SPC574 for VCUs), OE-grade Bosch CJ125 driver chips and LSU 4.9/ADV wideband sensors, and a MathWorks MATLAB/Simulink-based model-based design flow supported by proprietary tools EcoCoder (auto code generation), EcoCAL (calibration) and EcoFlash (flashing).

The product portfolio spans four pillars: (1) small-engine EFI conversion kits for Honda GX35, Briggs & Stratton Junior 206, and general 35cc-300cc and 400cc-800cc engines; (2) UAV-specific EFI systems with 30-50% fuel-economy claims over carburetors; (3) the ALM family of wideband lambda controllers (ALM-LSU ADV, ALM-LED, ALM-Inline, ALM-CAN/II, ALM-Board, ALM-RS485, ALM-II Dual Channel); and (4) an EV-controllers line of ASIL-D rated VCUs (EV2274A, EV2274KAH, EV22297A02) and HCUs. Revenue is generated primarily through direct hardware sales to small engine manufacturers and UAV OEMs, supplemented by a qualified dealer/distributor channel offering volume discounts, with custom EMS projects (battery-less, direct injection, multi-fuel, heavy-fuel) handled on a quote basis. Pricing is one-time/perpetual with a 1-year warranty, 20% restocking fee, and $35/hour repair labor.

Ecotrons serves a heterogeneous customer base across education (Shell Eco-Marathon and Formula SAE student teams), UAV/drone manufacturers (3W, Desert Aircraft, DLE), small engine OEMs producing 35cc-800cc powerplants, the aftermarket conversion segment, and — through the newer VCU/HCU line — electric and hybrid vehicle manufacturers seeking ASIL-D rated supervisory controllers. The website lists payments in USD via PayPal, credit card, or wire transfer, and the checkout function is currently disabled due to semiconductor shortages, indicating some supply-chain friction.
