Tom, throttle response is indeed improved with Blue Drive off since that is what Blue Drive changes. With it engaged, it reduces throttle tip in and output response for a given accelerator pedal input. I feel the throttle tip in is a bit aggressive with it off just like most Hyundais with an Eco button so I drive with Blue Drive engaged all the time.
I start out gently and try to make it through 3rd or 4th before engine engagement. If you have a high SoC , you can do this with the pedal. If its in the 5/8 range or so, I will drive up to maybe 15, shift to N, shift back to D and bring her up to my target. The key use of this however is not to drive on EV but to maintain EV between stop lights. The one place you do not want the ICE to spin up is with a yellow or red ahead three blocks or less. If I am accelerating in a suburban environment, I will allow the ICE to spin up at ~ 20 mph and allow the HSG to begin charging the LiPo pack as quickly as possible. If you watch this action on an SG-II or e, you will see 20 to 30 MPG on the iFCD when the OEM iFCD is pegged at 50 MPG . This is what you want as the total after the Li-Po pack takes over will indeed give you a 50 MPG plus cycle.
Regarding P&G, you allow the battery to P&G but you do not want to P&G the HSH on your own. When the engine is running, it is placed in a very opportune point on the BMEP to provide just enough power to meet your demands while giving as much power to the HSG to fill the Li-Po as possible. What I do is force glides on any downhill no matter the SoC but at somewhat steady state cruse with a Drive with Load (DWL) approach. Meaning I keep the iFCD pegged at 50 MPG as much as possible which allows the pack to charge from the HSG as quickly as possible to do some EV mode driving down the Interstate. If you try and accelerate harder than the pegged 50 MPG OEM iFCD , you will lose overall FE which is something I try to avoid at all costs.
I do drive in D most of the time but if I have to force a glide (the SoC has not yet been built up to ¾ or thereabouts, I will let off, force a few ms of regen which shuts down the ICE and shift to N for a glide when appropriate.
When I get to the San Diego area, maybe we can go out for a clinic if you are free?
IHTHs.
