8. Technical Services' Chad Hudson (right) supervises a college intern as the engine is being programmed and tested. The console on the right shows the dyno readouts; on the left is the engine ECU calibration program. A basic "start-up" program is installed into the programmable ECU. From there, the engine parameters are monitored and adjusted in 200-rpm increments from idle to whatever rpm is deemed necessary. Tiny changes in the fuel and timing maps are made in each of these 200-rpm increments. These changes affect power, economy, and durability. Though Hudson felt that with another few hours' work, he could have coaxed a few more ponies and pound-feet out of the UNO engine, he was largely happy that we were getting pretty much what the engine had to offer.
