Here’s what we have observed so far:
- Better starting and running in very cold weather. This project started in the middle of a very cold winter (in Topeka, Kansas, USA, it can get to minus 20 F / -29 C some years, and that’s before wind chill), and my ’98 Tahoe was struggling a bit. This year on New Year’s Day the temperature went down to 10 F (-12 C), and that’s cold enough, and she started up just fine this morning (Jan 2, at 5 F, -15 C).
- Better gas mileage. With six of the current little electronics packages in place, mileage improvement of 2.8% was measured in a repeated 20-mile run.
- Better power underfoot. The nearest dynamometer I’ve located is 85 miles from here and quite expensive to hire, will have to do it sometime.
- Cooler running. This is taken from observations of temperature gauge in one vehicle, and reduction in overheating in another! We’ll have to extract hard numbers for this somehow.
