Been real busy with work lately, so not much time for improvements.
The car is much cozier with the pre-heaters running before going for a ride. The last time I went for a drive, without pre-heating, the car did feel rather sluggish.
I finally got a chance today to play around with the car a little more - this time, working with the interface software to the Cougar controller.
Adam walked me through the software over the phone, helping me get connected up, and tweak a few settings. I should get a chance over the next couple days to tweak the controller to match it's settings to my particular motor. I should be able to get more power and better acceleration, just by changing some software settings. I am looking forward to it!
