EpicEFI STM32MEGA144 H743

Convert your Speeduino to EpicEFI/FOME/rusEFI This is primarily recommended for use with the UA4C, as all its components can work with the lower voltage this microcontroller provides. Most through-hole soldered ECU boards are not compatible Why wouldn’t I want the USB cable, it’s free??? Well it is not very long/useful and it adds an extra ounce to the package, which can increase the cost of shipping. With international shipments it could add as much as $10 to the cost, if it tips the shipment into the next weight category.
