After a few log entries and some BMS adjustments, some gains already appearing.
Logs are here:
2010 Factory Five Racing Mk4 Gas Mileage (DC Cobra) - EcoModder.com
The second and third test runs confirmed the first and were even higher, above 500 wh/mi.
On the fourth measured run, I drafted a trailer for about 3 miles, and got down below 400 wh/mi for the first time. Certainly some confirmation of air drag being significant.
The 5th drive included a long big hill and no drafting. The 423 wh/mi drive was only influenced by reduced pack balancing (mouse clicks) after the charge completed.
One last observation, on the way back down the big hill, with no throttle and coasting about 50 mph, the car either held it's speed or slowed slightly. My previous EV, a Saturn would definitely accelerate while coasting down that same hill with no throttle and starting at 50. More confirmation of drag...
