Section 1: Introduction The Flyin’ Miata piggy back ECU drives four auxiliary fuel injectors and provides tunable ignition retard based on a 16 column and 6 row map of engine RPM and manifold pressure. The ECU also provides turbo boost pressure control. A hand-held keypad in the cockpit allows adjusting of all the operating parameters. We have made the piggy back installation as easy as possible by using plug-in connections where ever possible. However, some wires will still need to be cut and spliced at the ECU. On 2001 through 2003 cars, the wires going to the ignition coils need to be cut and spliced as well, in order for the Link piggy back to intercept the ignition signal. For the wire splicing called for in this manual we recommend, and include, heat shrinkable crimp connectors. A crimp connection is better both structurally and electrically than a solder connection. If you do not believe us, try to find one soldered connection in the entire wire harness in your Miata. The integrity of a crimp connection depends on the quality of the tools used for the installation. Go to Sears and invest in a high quality pair of wire crimping pliers. These can be bought for $25 to $30 and will quickly pay for themselves in this and future projects. The included crimp connectors use a heat shrinkable coating. Once the wires are crimped in place, heat the connector with a heat gun (buy one of these at Sears with your crimping tool) to shrink down the outer covering. This will provide a water tight seal for the life of your car. Required tools Every project on your Miata presents the opportunity to purchase more tools.
