I got my RS 7.0 about 10 days ago; it currently has ~1000 miles on it.
Whenever I change gears, my engine seems to spin faster. For example, when you go from 1st gear to 2nd, you take foot off gas pedal and depress clutch pedal in order to switch gear. On a normal car, your engine looses speed as soon as you let your foot off the gas pedal, but my tC’s engine is actually turning faster even with the foot off the gas pedal.
So usually when I shift from 1st to 2nd, I do so around 2000 to 2500 rpm. So on my 1st gen tC, I would normally engage 2nd gear around 1200 to 1500 rpm. But on current RS, rpm would stay at 2000 or 2500 depending on when I let go of the gas for good 2 seconds, and by the time I am ready to engage 2nd gear, rpm is around 2000. This is making fast/smooth shifting impossible.
Is this normal? I have never had this problem on any other manual cars I have owned. Should I have the dealer take a look at it? I would really appreciate any input on this matter.
Thank you.

 

simple issue due to drive by wire so it holds throttle a for a bit after you let go of the throttle. it is normal and if it bothers you a lot you can fix it with a throttle controller (weapon-r or another brand i can't remember). otherwise the only other way is to get used to it :/

 

it's called rev hang. completely normal, although mine don't sound as bad as yours.
there are ways to fix it like previous post said, easiest fix for most people seems to be flashing the ecu.

 

wow...that is some short shifting. anyway, smooth shifting is easily possible with smooth throttle blipping and smooth clutch take up.

I have a turbo tC and a bmw 335i and i usually shift at 2500 to 3000 rpms under normal driving. why would you short shift that much?

 

i shift at 2500 rpms as well.

 

a throttle controller will fix that,twp has a really good one and for cheap,really works,i myself had one......on a normal day i shift between 2500-2800 rpms,but never at 2000 at the engine is working harder,higher the rpm doesnt have to work as hard,but i guess you gotta save gas some how

 

Yep Scion really dropped the ball on the dbw lag. Gotta get a throttle controller.

 

haven't driven a second gen tC, but it isn't that bad really. honetly, my BMW has more throttle lag than the scion does.

 

not to get off subject but i noticed that in the new bmw's the 335i,you step on the gas and take a few secs to kick in

 

Guesstimate the amount of time the revs hang for, and try to let off the gas about that long before you shift. This way the revs will begin to fall just after you press the clutch.

This is how i manage to get smooth shifts on my Tc2, though it is a solution to a problem that shouldn't exist...

 

Yeah, mine is an 07 335i sedan with the n54 twin turbo engine, the current ones have the n55 single turbo engine. You don't notice it when say, you're driving with your put applying partial throttle, and you push it to overtake somebody, but you really notice it when you're off the throttle in a turn, and then you get back on the gas to accelerate out, and there is a noticible delay in response. that is where I notice a HUGE difference between the BMW and the scion throttle response.

 

Thank you for the information. I guess I am going to have to learn to live with it, or get the controller.

I did/do this with all my new cars, I take it easy on the engine for first 1 to 2k. and also, even if its not by much, I would like to save gas. People have different preferences. Personally, no need to rev the engine up when I am driving on the suburban road. I'm not out there to set 0-60 record time.

 

yeah, i understand that, just seems like the engine really wouldn't be spinning fast enough to cruise comfortably at those rpms. I find that between both my cars, 2-3k rpms is where the car likes to be so the engine is running efficiently, but not struggling to move the car. seems like the tc's engine woule struggle at 1500 rpms unless on a downhill slant.

 

/\ This - but in all honesty wring it out a bit more. The reason this happens goes back to the early days of emission controls. Carbureted vehicles used to have a deceleration valve that essentially did the same thing. If you let off the throttle it will still pulse the injectors (worse in carb days) and result in unburned fuel exiting the tailpipe. The EPA hates unburned fuel so we have to deal with the prolonged rev to burn the fuel.

My carbureted 454 chevy drops like a stone when I lift off the gas...but that's a different story - and no decel valve.
