Rebuilding, repairing, modifying, or upgrading your Hot Rod or Custom Car involves a wide range of technical skills one of which is electronics/electrical design Integrating new electronics into older model vehicle platforms is rarely a simple plug and play process. Electronic ignitions require timing and fuel mapping adjustments and upgrading instrument cluster or individual gauges often requires a calibration process to scale the transducer measurement range to match the gauge indicator display range. All of these electronic upgrades require that the electrical system has a wiring harness that is reliable and all ground connections and current capacities fall withing the wire size and terminal lug specifications. Creating a good electrical foundation helps ensure reliability and peak performance.
Another critical design factor is mechanical/machining design and fabrication. Integrating new design ideas or fixing current performance and drivability issues is rarely as easy as replacing parts or installing new parts without some amount of modification or fabrication adjustments. These adjustments ensure the parts will fit and perform according to their design specifications.
Successful implementation of both mechanical and electrical design aspects are critical to a car that performs reliably and is enjoyable to drive.
