June 29, 2011 - Good news!
The engine computer is back from being reflashed, and it's working far, far better than before. Many more horses now live under the hood. It's not yet perfect, but it's now running in closed loop and with long term trim so it'll get better. Best yet, I can now get in to the computer to tune it. So we're well on the way.
I also discovered an advantage to flexible air dams. There's a piece of road nearby that was torn up for construction and hasn't been repaved. There's a slight drop down to the gravel/dirt level. Well, when I (purposefully) took this at a high rate of knots, the air dam bottomed out and became a snowplow. A truly impressive cloud of debris was raised. Back in the garage, there's no damage to the dam and a few screws that have pulled out. I was going to replace those with bolts anyhow, so no harm done. And yes, I do need to lift the car up. I'm pushing it right now to find out where the weak areas are.
