Dual Curve is a division of Autotronic Controls Corporation that provides research, development, sales, and support for a variety of electronic components used on automotive LPG and CNG conversions. Autotronic Controls originated in 1970 by developing a ground breaking multiple spark ignition system for extremely lean burning fuel systems. Nine years later, Dual Curve was introduced as a department specializing in ignitions with timing advance for propane and natural gas powered vehicles.

In the 1980's, the growing concern over increasing pollution led to the implementation of emission regulations. Consequently requiring significant technological advances in automotive diagnostics, and subsequently generating a demand for fuel control and diagnostic support devices for alternative fuel vehicles. In the 1990's, Dual Curve continues to successfully meet those demands and advances through a second decade with the introduction of the integrated processor product line.

At Dual Curve, we design, develop, manufacture, and supply electronic equipment and accessories for closed loop fuel control, timing advance, and diagnostic support for alternative fueled vehicle applications using air valve carburetion. These applications range from almost any open loop vehicle to late model American made vehicles, with second generation diagnostics. We conduct our own Dyno testing, Five Gas Analysis, and road testing on vehicles to help conversions meet today's stringent emission standards. In order to ensure our products help meet these standards, we also provide technical and engineering support to our distributors involved in testing vehicles for emissions at nationally recognized emission laboratories.

The Dual Curve division consists of an experienced engineering team; a production staff committed to excellence; a meticulous quality control department; our own web site designer; and a professional, courteous, technical-sales support staff. We also count on a network of trained and experienced distributors to represent and support our products throughout the United States, Canada, Mexico, Europe, and Australia.

We plan to continue on the path of innovation and quality well into the next millennium. We are dedicated, and determined, to take full advantage of the latest technology to continue to stay in the forefront of the alternative fuels industry. Our engineers are constantly researching, and evaluating state of the art microcontrollers, innovative programming and production methods, in order to improve our efficiency and product reliability. Together with our sales and service staff we plan to maximize our use of the Internet, e-mail, and latest graphics to let the world know what Dual Curve is all about. Our reputation as a recognized and respected leader in the industry motivates us to continue to work hard at providing a reliable product. We plan to inject some adrenaline in the arm of the alternate fuel industry and look forward to the challenges the future may bring. We look forward to being there for you.
