Highlights

Fits: Facelift MX5 NB with VVT Naturally Aspirated engine from MY2001-2005, Facelift MX5 NB with non-VVT Mazdaspeed Turbo 1.8L engine. This ECU works for manual transmissions only. Includes onboard MAP sensor. Most factory features are supported. This ECU will need an expansion connector before E-Throttle is usable. This Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection. Use the CANJST4 (Link PN 101-0198) cable for connecting CAN devices. This new 4 pin port and cable provide not only the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices. The power supply is protected by a self-resetting fuse rated at 3A continuous.
