Do any of you HCH or HCH2 owners use pulse & glide routinely?
If so, can you comment on these things:
1. Describe specifically HOW you do it
2. Describe WHEN you do it on your commute
3. Describe WHY you do it - how does it help your FE versus using other driving methods
I tend to just use CC (a lot) on my commute but would use P&G if I knew HOW, WHEN and WHY to do it.
Thanks for your thoughts.

I would say I do something of a modified P&G in my HCHII. I think the simplest definition is "speed up - glide - speed up - glide." I typically don't focus as much on the speeding up interval as I do getting up to speed naturally and then trying to pick the best spots to EV Glide for as long as possible. That said, I know if I were to focus on the speeding up part I could improve, but on my (admittedly advantageous) commute I knock out 60-63mpg both ways just about every day in the summer.
Here's the problem (one I understand MSantos is working on) -- P&G in an HCHII is difficult (for me, anyway) because it hits the pack really hard. The first time I tried aggressively P&G-ing I got down to a forced charge from a full pack. There went the segment. The trick is to accelerate at a rate that invokes minimal assist. Harder than it sounds. As I understand it, MSantos' hack will allow one to inhibit the assist part of accelerating, allowing ICE-only pulses.
For my purposes, then, the modified technique I employ both prevents many forced charges but still allows me 60+ mpg. I also rarely have the luxury of no traffic behind -- my commute is mostly two-lane roads with moderate traffic -- so I tend to avoid the rubber-band effect of P&G. That's a personal choice on my part, for what it's worth. --RN

Sorry - Msantos and others turned me onto other threads that deal with this. Please close this thread.

No problem. Some information is already posted in these threads:
