Prior to heading to the track, Horace adjusts the engine's computer using his laptop. Once we had the tune we needed, the car ran like a champ. The very first time we hit the starter, it fired up. From then on it was just a matter of refinement. With a race system like we envision, the computer adjusts for everything: fuel density, air density, temperature, and more. There would be no more carb adjusting or flames out of the exhaust using fuel-injection.
