The MegaSquirt v3.57 ECU: The most popular ECU in the world meets state-of-the-art surface-mount manufacturing technology.

MegaSquirt is capable of controlling the fuel system of almost any production engine... from a Briggs and Stratton mower engine to a supercharged V8, and everything in between. Our v3.57 ECU's are professionally reflow-soldered by Bowling and Grippo with final soldering, assembly and testing by RS Autosport. Each ECU is housed in a top-quality brushed and black anodized extruded aluminum case, with CNC-machined panels.  The MAP sensor is internal, and connects to an external hose with the built-in 1/8" hose barb.  All RS Autosport MegaSquirt ECUs are fully tested and carry a 1-YEAR HARDWARE SUPPORT WARRANTY against manufacturer defects or faulty electronic components. Special attention is paid to workmanship and clean solder joints on our ECU's. We encourage our customers to crack open their MegaSquirt ECUs and check out the quality of assembly...  We're sure you'll be impressed!
