Yay!! Finally hit the 50mpg average mark over a full tank!!

I'd attribute hitting that target to more aggressive EOC (starting to do EOC for shorter distances now; normally I've been doing it on longer downslopes, but now I do it on shorter (and gentler) downslopes as well), better (warmer) weather, and some luck (a few great drafting opportunities, for instance).

Had a little trouble toward the end of this tank with engine stalling; turned out I had forgotten to tighten a ground wire when I switched back to the Cali ECU. Once tightened, no more stalling problems.

Went to a wrecking yard this weekend to get an ECU harness along with the ECU connectors from an ECU so that I could build myself an ECU jumper harness. Cheapest I'd found that was $70 pre-built; still a bit pricey for me. Spent 2 hours at a Pick-n-Pull (they don't organize the Japanese makes, so 45 minutes was spent just finding the right year Honda!) and ended up with the parts I needed for $10 (plus tax). I wanted to get the jumper harness before installing the MPGuino so that I had a way to tap into the signals without cutting into the stock harness. So now I'll need to spend time soldering all the wires...
