___You are mixing some items up here. DB was a mode the early Prius II drivers were searching to achieve when the answer all along was in the Glide. I am glad I was weaned off of it by the second time behind the wheel. Forget about dead band on a pulse. You want to see the ICE-On, arrows from the ICE to the wheels and to the pack during a pulse. Nothing else matters or is particularly useful.
P&G plus Warp Stealth in the Prius II for maximum FE …
___A new driver with a brand new Prius II in colder temps may have some problems with the perfect Glide which is where you want to see nothing but a blank screen other then the ICE, Wheels, MGSet, and Pack mimics (no arrows).
A) I have never driven a Prius II with a tach via SG-II, CANView, and analog tach (that I was watching anyway) so I can’t answer that one for you … I can tell you that 105 + is available from a 50 + mpg pulse, a 16 - 20 mpg pulse and everything between if you have the opportunity to take the Glides out the proper distance. When it warms up, the Prius II starts working like a knife through warm butter and you will quickly become an expert to its particular brand of a natural P&G.
B) The best Prius II FE I have received came about running the SoC at 2 to 3 Blue bars max in temps from 65 - 78 degrees F. Running a high SoC can be a waste of effort and heat other then for heavy stop and crawl traffic conditions where a lot of EV would be involved.
1) Forget about Dead Band on a pulse.
2) This is an area where I think many lose what is available from their Prius II’s. Once you begin a pulse, keep accelerating to maintain your iFCD in a given but tight range. I have seen far to many times where a driver seems to let off while the iFCD climbs and carry a pulse for far too long. Once you have begun your pulse at your own predetermined rate to match traffic conditions, recognize it for what its worth and don’t let off.
3) Where are you reading this discussion on dead band?
4) Your built in Energy Monitor screen.
5) Forget about DB on a pulse. Concern yourself with quick transitions to glide in traffic and without + judging traffic and such to extend your glides when and where appropriate.
