Maruha Dimsport Rapid Module – Fuel And Timing Controller – 1989 to 1993 Miata




Maruha spent the past few years working with Dimsport to create a fuel and timing controller for the NA and NB Miatas.  The new Rapid Module works with the factory ecu and comes with a harness and connectors that plug directly in to the factory connectors.  We have installed and tested this module ourselves on Vu Ho’s 1999 Miata in Laguna Hills, California.  His car fires up with no issues and drives very good.  Our dyno results on Vu’s Miata shows gains of 3.8 hp and 7.04 lbs. of torque with potential to extract more.

Tested on:

1999 Cylinder Head, Skunk2 Intake Manifold, Stock Throttle Body, AutoExe Carbon Fiber Intake Box, 2001 Engine Block, Maxim Works Headers, Flyin’ Miata Midpipe with High Flow Cat, Car Make Corn’s Muffler
