I've been reading on other cars that use that technology (RAV4 for example) and sometimes you press on the gas and nothing happens for up 0.5s b/c computer thinks opening throttle fast will adversely affect gas mileage (or something like that).
Yes, this is what I meant - I am a software developer myself. This is why having computer control a throttle just doesn't give me that warm fuzzy feeling...
I have personally driven both the v6 and hemi and I didnt notice it...but I wasnt looking for it either. See what o come up with on your test drive Sat. and report back to us
2007 Libertys have really slow electronic throttle control due to an old, slow bus.
The Grand Cherokee has always been CANbus so it doesn't have that issue. When you hit the gas pedal, you go. There is no waiting.
I think what you mean that "power steering" used to mean "hydraulically assisted" (using pump) and now it is often "electrically assisted" (using electric motor), right?
So how does that manifest itself? You turn the steering wheel but car keeps going straight?
I agree our 2011 has horible throttle response... and it takes forever to really get into any power off the line... I cant wait for programers to become available... there is really nothing out of the hole... After you mash the peddle you just wait... wait...wait... then bam it starts to pull. But this is why the aftermarket exsist... Most people may never notice the lack of low end... or what ever is there may be enough for most... But I can feel it being held back... This lack of low end could be blamed on the 3.42 rear gears... I can see them causing throttle lag.
The throttle lag is very annoying on my 2011 six cylinder. I look forward to Jeep coming out with a fix for this and I hope it is soon. Can't believe Jeep isn't having all kinds of complaints on this specific problem. It takes the fun out of driving an otherwise superb vehicle, in my opinion. I have tried to modify my driving to accomodate the lag but it just does not work, it is there well over 50% of the time when cornering or leaving from a stop at a stop sign. Please tell me that Jeep is aware of this issue and understands it is a serious flaw in their product.
You MAY be able to improve it if you, without the engine running, switch the ignition to ON and pump the gas pedal quickly three times, then start.
This will calibrate the ETC and give it faster reactions for a period of driving.
Electronic throttles aren't all bad - the one in my RX-8 is very good.
I find the selec-terrain to have a huge impact on throttle response. Left in auto mode it seems to be vague, slow, and combined with a strange operation strategy of the lockup in torque converter for what I can only guess is for fuel economy.
In sport mode the throttle response is very good with much better shifting and torque converter strategies.... except mine seems to not always shift into 5th gear after you get up to speed and cruise
