A Side Oiler Like We've Never Seen
To tune the engine for driveability, many situations are simulated to determine the optimal air/fuel ratios and spark timing. To perform the testing, Van Auken drives down the road at a constant rpm and slightly tips the throttle while Henninger reads the air/fuel ratio and other parameters like temperatures, pressures, etc. Henninger then changes the fuel/spark tables to optimize them based on the readings in these situations. This is done for situations like low-speed cruising (25, 35, 45 mph) and high-speed (70, 80 mph) cruising. Most of the wide open throttle (WOT) parameters are determined on the dyno.
