Hi guys,
Pwr mode is going to provide downshifts more easily than normal mode. It assumes you'd rather drop down a gear for the extra "power". So, for example, when you go to pass and you put your foot in it the trans will downshift more than it would with the same pedal pressure at the same speed in normal mode.

It will also hold the trans in a lower gear longer for quicker starts. Try it and see where your tach shows the shift point from a standing start with pwr off and on. In the pwr mode the shift point will be higher


As ref. from a previous post.
My question is,Is this not what "E Shift does?.If this is true then E Shift would make power mode redundant,unless power mode also controls fuel/air mixture or some other aspect of the HP development process.Need some feedback to understand if there should be an either or.
thanks

 

well with e-shift you have to shift yourself if you want the quick responses, this just makes you car a bit more 'peppy'

from what i know this only affects the transmission.

 

clivej - I agree with your assessment of power mode, and I leave my car in power mode all the time.

e-shift lets you limit the highest gear the trans will shift into, but i think that's it.

 

Hi guys(ladies included),
I tried leaving my car in power mode also,it did not eliminate the slight hesitation nor did it dramatically decrease my down shift time,what it did was reduuce the time it took to red line (woke up the horses) and i got the impression that all 300 horses were very thirsty(gas needle fell rapidly). Now if thats all it does and e-shift takes care of the shifting which i find has very little hesitation,result of not having to the tranny search for optimal gear,then the owners of the 430s are at a disadvantage! could be thats why they increased the torque,just not enouge to compensate for e-shift.just my .02.
what do you guys think

 

Everytime I put my car in manual e-shift mode, it seems to be a lot heavier.

On automatic, I can drive the car so smoothly and without any jerks. For example, when I let go of the gas pedal when in auto, the doesn't jerk at all, but when I let go of the gas pedal in e-shift mode, the car jerks really hard.

And I don't even seem to notice any faster accel times when in e-shift mode, therefore I never ever use it.

My cuz has a 99 Acura TL with its tiptronic trans. And when I drive it on manual mode, it runs sooo well, just like someone would expect it to. It gives no jerks at all and you can actually feel and notice the extra power it provides. On the GS400 however, automatic seems the best way to go ! Ofcourse my GS is a lot faster than his TL, but his TL is a lot more fun to drive simply because of the way its manual is on the gear shifter (tiptronic instead of racing-car style) AND it really does seem to give extra power on manual.

 

When in auto, the car stays in the highest gear possible and tries hard to keep rpm low, so taking your foot off the gas means there won't be any 'engine braking' because the rpms are likely to be low. When in e-shift, unless you're in '5', chances are your rpms are higher than they would be when in auto, so when you take your foot off the gas, you get more engine braking which you call 'jerking'.

Many people WANT that jerking, because the engine braking means not so much actual brakes have to be used to slow down the car while at the same time keeping the rpms higher so acceleration is better when the driver wants to go again.

Sounds like you don't drive very aggressively.

I don't use e-shift very often, but it is very cool if you want the car to be its most responsive.

 

But I would think that when using "engine braking" it puts more pressure on the engine to slow the car down. I may be wrong, but I would think that this pressure on the engine would reduce the life on the engine, and it is much easier to replace brakes than the engine itself.

You are right, I don't drive my car aggresively, especially not in town. And I also see what you mean by the car being more responsive, it seems as if you have a lot more control over the car when using e-shift, engine braking, and higher rpm/lower rpm at your own command.

I rarely ever use power mode, but would it also contribute in comfort the same way as the e-shift does? In other words, would it jerk if I let go of the pedal? I don't mind it jerking and flying off when I stomp on the gas pedal, but when I let go of it I don't want it to immediately jerk nor do I want to REALLY feel a sudden decrease in applied power, if you know what I mean.

 

you wont expierince any jerking in power mode only on the E-shift mode I personaly love the engine braking especialy if you have an exaust system on the car it sounds awsome when it winds down from higher RPM's and people look at you like what does this guy have in there SRT HFI/ECU + Borla S/S excelent mix for an awsome sound

 

Well I don't like extra noises anyway, but still, the SRT HFI/ECU seems to be so good from your reviews that I am willing to sacrifice quietness for that extra power !

But I don't think i am ever going to get an exhaust, unless they make a nice dual-tip chrome exhaust that is even quieter than the stock !

 

hey Biggie, gotta agree with you on the engine braking sound with an exhaust!!

i Love the way GReddy sounds on an off ramp!!! 5-4 4-3 3-2 :eek:

hehehe

i love it but i think i'm hurting my baby at the same time! oh well....

better a good life short life that a long crappy one! (for me, relating to engines)
