You might want to skip over to Endless Sphere and read some of the stickies and archives there. The e-bike board here can be sorta quiet. Things are a little more lively over there, though I do find the discussions can be a little off the deep end, tech-wise.
If you're looking for feedback on battery power remaining, amp hours consumed/remaining, human watt-hours contributed, speed, distance, etc, then you really can't get any better than a Cycle Analyst v3. I have a BionX kit on one bike and a DIY set up on another with a Cycle Analyst. The CAv3 is hands-down the best I've seen for providing detailed reams of data about your battery and your ride.
Also, that said, I'm not an expert, nor do I play one on TV, but have you considered swapping your battery out for a 48v and going the over-volting route? My DIY has a 36v 250w geared front hub motor. My original battery was 36v and performance was just abysmal. I swapped the battery out for a 48v setup and haven't looked back. The motor is faster, sips juice more efficiently, and is just much happier running at 48v than 36v. For me, overheating hasn't been an issue, but then it hasn't gotten above 55F here since November.
