TSX / K24a2 Engine: Help!

[rh77]

Here's the situation:

My wife has been driving efficiently in the TSX all week by using constant throttle on hills, and using the instant feedback display to keep the FE above 30-35, despite the hit in speed. She managed to get 32.0 mpg on the last tank, which is darn good.

So, we hop in the car last night and run some errands. I'm using my usual Integra techniques, keeping the revs between 2k-3k on accel, CODFISH, ICE-on coasting, shutting down at long lights. Long story short, I killed the FE by 0.2! Boy did I get an earful, "I've worked hard all week to get up to 32, which is my personal best, and you come in here and ruin it!" I did, indeed, and was frankly disappointed. We had to take it out on the highway and really work some magic to get the number back up to 32.0 before fill-up. She says that every time she starts up the car, she loses 0.1 on the FE avg.

So, engine-off coasting might not be the best option for this car...

This LEV-2 system is something else. No EGR because of the variable Cam Timing, throttle by wire, etc. What do we do here? It does have the auto-stick transmission, but the ECU probably works agains me -- argh!

The only mod is tire overinflation. Coasting with ICE-on-Neutral has been found to be beneficial. The car already has partial under pans, airflow tabs in front of each wheel, and an awesome emissions system.

We'll talkin' "New School" tech. Any K-Series gurus out there? How do you hypermile this puppy...
