Hi, i am Ken. My 05 AT coupe has more than 2k on it now. I wonder if it's okay to have fun now? Like... shift in a higher rpm. Also, what range is the best shifting rpm that can push the car to its potential without hurting it? Thank you for your reply.

 

??? no advice at all? So many people have view it.... -_-''

 

Yes, you're beyond the break-in period, so you can have all the fun you want now. You have an auto, so just floor it and let the computers decide when to shift. They're programmed so you can't hurt the engine. Don't waste your time with the manu-matic mode - I've found there's way too much of a delay between your input and when the tranny actually shifts to be useful in getting any faster acceleration. Just leave it in automatic mode, and have fun. When you floor it, it'll take it right to redline anyway.

The VQ is a pretty strong engine in stock form, and there's plenty of redline cushion built in before parts start flying through the block, so don't worry about beating on it. It'll take it, and beg for more.

 

haha, great, thx

 

Well if you think the manumatic mode has too much of a delay, you haven't driven other manumatics then, mainly the BMW 3 series SMG. You hit the paddle and it'll shift about 2 seconds later. I know the M3 is a different story.

I found after test driving a lot that the G's manumatic mode was one of the best. Better than Mercedes, BMW.

 

I completely disagree... 1st gear in auto mode doesn't take you quite to redline, it shifts at 6100RPM. There is more lag when it shifts in auto-mode than in MM mode at full throttle. At part throttle there is lag in both modes.

Use MM mode and push up @ 300 RPM before redline in first and it will shift right at redline. In second, do the same at 200 before redoline... The higher gear you are in the less delay. In MM mode the engagements of each gear are more direct and you can feel/ hear the difference. You can also double downshift.. Two quick taps down on the shifter, but lift the throttle or there will be more of a delay... If you get a grounding kit , the delay seems to lessen and it becomes easier to double down. I have achieved tripple downshifting on rare occasions, but that is difficult to duplicate.

There was a roadtest(I believe by Autoweek) in which the testers where able to acheive better times in MM mode than in D.

 

personally love MM mode..

 

"I found after test driving a lot that the G's manumatic mode was one of the best. Better than Mercedes, BMW."

I don't know what you test drove, but after owning a 03' G35 and now owning a 05' SLK350, the manumatic on the MB kills the G35's. Maybe it's because I prefer the side to side shifting instead of the traditional up and down.

 

At the time, I test drove an '04 CLK I believe. Yes, the shifts were smooth - a ton better than the BMW, but I think the G shifts smoother. Maybe its the bigger engine that can compensate or maybe it was just the car? I dont know.

 

KAHBOOM is correct, you can get a little more rev out of it in MM if you do it right and it does help in faster accel.

MM is also great when you want to hold a gear - like in the hills/turns, where you may let off the gas, but don't want it to upshift.

MM also protects you from downshifting at what would be too high a speed/RPM
i.e. it won't let you downshift from 3rd to 2nd at 80MPH, you have to get down to about 60MPH before it will allow it, etc

 

high rev does not equal better acceleration. You're better off shifting early on
this car to use the max torque. hi RPM is just blowing smoke on this car.

 

I used MM mode and eventually learned to just time when to shift.. If you know its gonna lag a sec or two then just shift a second earlier from hitting redline. Or get some Grounding Wires =) I redlined my car the first day I got it haha.. and only a couple times throughout the break in period.

 

Kenchan....

It is not that high revs get you more power, it is about where the
revs are when you shift to the next gear.

If you shift early as you suggest, when the car hhits the next gear
it is at a much lower rpm than max torque or HP.

The goal when doing what is being discussed) is to try and keep it in the
top of the power curve.

 

In addition, shifting at 6100 is not the optimum shift point in 1st gear on this car... It is closer to redline because of what Sickone said. In 3rd gear you want to shift right at 6300 a (little less than redline), because your power curve drops too quickly for the gearing setup in the car.

 

Wow, thanks you for the reply.
Most of you guys said to shift the car right before redline. Do you guys do that alot? Is that killing the car? This morning, i tried to shift at 5000rpm, i was afraid to let it go higher because the car scream(WEEEEEE) kinda loud.

Also, how much does the sound different with a Z tube?
