This research examines potential improvements in post-production vehicle fuel efficiency, and establishes a set of equipment and protocol for further research into fuel efficiency improvements.
Fuel efficiency of post-production vehicles can be measurably improved through the modification of the coding of the ECU of the vehicle to manipulate the air/fuel ratio and spark ignition timing of the engine, resulting in an increase in fuel efficiency without a noticeable decrease in automobile performance. This low-cost modification, potentially applicable to most cars built in the 1980’s and later, requires minimal investment on the part of the vehicle operator, and fuel savings may offset that cost.
