Our newest generation plug and play ECU and harness kit is now available. The MS3Pro Mini features a fully weather proof AMP sealed connector, relay and fuse box, fed through a main power line protected by a 100A MEGA Fuse. Each harness is labeled at each connection, and tested on our in-house test engine for quality control verification before getting packed and shipped out to your door.

We intend for this kit to completely replace our MS2 line-up, however we are still offering it at this time until further notice. However for it’s price point, it’s a really hard product to beat for the money. Not only is it POWERFUL, you get all of the benefits of a MS3x setup, at MS2 level pricing. This ECU is also HALF the size of the MS2/MS3 Case, and you get to ditch the DB style connector. This means it will fit under your factory trim.

The final added benefit is much faster lead times. One of the main contributing factors to our lead time is modifying the ECUs. This requires a properly trained technician to solder components and jumpers to the mainboard, which will no longer be required, saving an entire day in production time.

This kit comes as a fully plug and play option for the 1970-1983 Z cars. Does require use of a 1982-1983 280zx Turbo Distributor. If you don’t have a turbo distributor, we do have the option for a drop-in crank angle sensor for use with multi-coil spark.
