Glad everything got sorted out for you. I believe another member mentioned that the update consists of two flashes of two different ecu units. The problem you had resulted from the second update being flashed before the first was successfully completed. The other FYI is the Persona has 17 inch wheels, so initial acceleration might be a tad slower due to the heavier mass of the wheel/tire combo, which places more weight toward the outer circumference of the wheel.
What climate settings need to be manually selected every time? My a/c seems to be at the same settings every time I start my car. As far as power mode, I have driven other cars that have had different modes and they always needed you to select them each time you started. Personally, it makes sense that it defaults to "normal" mode instead of power since it is called "normal" mode for a reason. I usually keep it on eco. It stays in eco with each restart and I just prefer to save as many mpgs as possible since that is the whole point in buying a Prius.
Seems as though ECO is to the left of the center line, normal is to the right (Eco light goes out) and power is the red zone beyond that when the pedal is further depressed matter which "mode" is selected. The more I drive it and observe this the more I think this whole discussion is purely accademic.
I read the whole thing, page 49 says it is just a pedal position adjustment, what page says what you claim?
*I* made no claims -- must've been someone else that you're thinking about; however, this link has similar info at bottom: HSI
You are correct, my apologies. I am wrong. I was just confused. Somehow I thought your find was this elusive pamphlet.
Naw, I just recognized the image and remembered that I had saved the link address in my Prius Info folder. There's this Australian Toyota website description of Prius-V ECO, EV & PWR throttle-control modes: Eco driving - Toyota Prius v this Wiki site: Operating modes (ECO, Normal, PWR and EV) - Prius Wiki and, this UK Toyota site: À-la-mode – Prius’ driving modes match the moment « Toyota UK news, reviews, video and pictures
in post 38, stratman said he was reading a pamphlet at the dealership. i don't know what it was, but made claims i have never heard before.
I wish I had taken it home now. It was actually one of those colorful brochures printed in 11x17 inch coated paper and saddle stitched (2 staples in the center and folded over into a booklet). I distinctly remember the claim although it may have been 55 to 70mph, but definitely remember the 1.7 sec decrease in time.
I would however take a sales brochure with a grain of salt as data is often cherry picked and or taken out of context. Good example is in sound systems. It may have less than .02% THD when tested with a base 10 (1000hz, 10khz) signal but put 20-20k through it and it's actually more like 10% THD. The marketing department whop repaired the info isn't going to share that with you. Also, if the term RMS Watts is in there it wasn't written by an engineer. No such things exists. RMS refers to a wave, a watt is (for all intensive purposes) heat.
My theory is that when your in power mode, your electric motor output is at maximum performance and will consume maximum power (that is permitted) in the battery till it gets low then the engine will double duty as a generator for the electric motor and power the wheel while the ICE remains the same as in performance as in regular mode except the throttle body is altered to be more more sensitive while the Power split device characteristics is changed by allowing the engine to operate in a higher rpm band by changing the ratios at a higher RPM.
You are (of course) free to have any belief you want, but all of Toyota's literature claims it is just pretending you mashed the pedal father than you did.
No argument from me about feeling lighter and faster. I actually think it's just more responsive like a normal car. Not a car that encourages more economic driving. The Prius "normal" mode is akin to most regular vehicle's "Eco" mode (if their Eco mode can affect throttle response). I do prefer the steering from a Honda compared with Toyota - Toyota's just require too many turns of the wheel! It's excessive. I've had the car for a bit now and I still mis-judge some turns because I am used to the Honda Fit steering.
The car does remember the climate temperature and mode setting but the fan speed may change drastically. The power mode selection does reset on other vehicles too. I just prefer the user interface of other vehicles. The button placement and size and drive feel could be better on the Prius. The awesome fuel economy and reliability are worth the small inconveniences the interior layout presents. I would be interested to drive the Ford, Honda and Hyundai hybrids before I buy my next car.
When I look at that green picture, showing Motive Force Output (ICE+motor response) vs. Accelerator Pedal Opening, I translate it as saying: • PWR mode = the computer "responds" more (a) quickly (ie: above the blue NORMAL line) and (b) aggressively (hump) in middle of pedal opening/depression in response to the drivers' NORMAL foot-pedal movement. • ECO mode = the computer "responds" more (a) slowly (ie: below the blue NORMAL line) and (b) laggardly across the whole pedal opening/depression in response to the drivers' NORAML foot-pedal movement. • NORMAL mode = the computer "responds" uniformly (ie: NO enhancement, NO suppression) across pedal opening/depression in response to the drivers' NORMAL foot-pedal movement. To me, it's saying *how* the computer 'changes/interprets/responds' differently to the drivers' pedal depression readings that it receives from the 'Accelerator Pedal Sensor' for each mode.
Power mode on my 2014 has much faster o-60 times and off the line much faster. It is darn right quick. ECO is not even close no matter how hard you jump on the peddle. H
In PWR mode, the computer tells the ICE+motor to "get-it-on" quicker & harder, producing more power, more quickly, which manifests as quicker acceleration...as you notice. Any sudden change in pedal depression is acted upon both faster & with higher effort (more HP). In ECO mode, the computer is 'dulling-down' the ICE+motor (and A/C!) response in the effort to maximize FE, which manifests as slower/softer/duller acceleration...(like slow-motion running in deep water)...as you also notice. Any sudden change is pedal depression is acted upon more slowly with lower effort (less HP = lower fuel consumption). Both "modes" are merely changes in *how* (PWR = exaggeration; ECO = suppression) the COMPUTER 'reads & responds' to your pressing down of the accelerator pedal.
