Megasquirt MS3 MSLABS Mini - MX-5 (89-05)
The Megasquirt MS3 "Mini" by MS Labs is a true plug-and-play standalone ECU for the Mazda MX-5 / Miata. The Mini board fits inside your factory ECU case and plugs straight into the OEM connector — clean, hidden and fully reversible. Your stock board comes out and stays with you. What it does - Batch and full sequential fuel injection - Wasted-spark or full sequential ignition — coil-on-plug / coil-near-plug (runs the Audi R8 COP coils) - Advanced knock control with DSP and knock windowing - Closed-loop idle control on the factory idle valve - VVT control (2001–2005 engines) - Electronic boost control — two boost tables, boost-by-gear and boost-by-speed - Flex-fuel (E85) sensor input - Alternator, battery-light, tacho, dual cooling-fan and A/C control - Internal MAP sensor to 43.5 psi of boost - Onboard SD-card datalogging, CAN-bus and USB Specifications - 16-bit 50 MHz processor with XGa
Megasquirt MS3 Mini: Plug-and-Play Standalone (89-05)
The MS3 Mini is a specialized engine management system designed for the first two generations of the MX-5. It bridges the gap between basic entry-level ECUs and high-end professional units, offering the high-speed processing power of the MS3 firmware in a footprint that allows for direct installation into the factory location.
For owners of the NA (1989–1997) and NB (1998–2005), this is the most cost-effective way to gain full standalone engine management with modern features like sequential injection, wasted-spark ignition, and real-time data logging.
