ok i'm not sure if what i'm doing is 'helping' the srm or not, but i'm not sure why my shifts aren't smooth. When its on, and i upshift lets say from 2-3, it doesn't let the revs below what they need to be for 3rd gear at a given speed. should that mean i let the clutch out quickly, or with a little finesse at the end. i feel like if i give it a little gas as i re-engage the clutch, which is what i would normally do, it becomes jerky. so basically what i'm asking is this:
If SRM is on and i upshift, do i let the clutch out slowly or quickly, and should i give it any gas before the clutch is fullly re-engaged? Also, when i downshift with SRM on, should i let the clutch out slowly or quickly? should i give it any gas or not until the clutch is full re-engaged? |

- When you're upshifting, the clutch shouldn't need to be let out slowly at all. It should, however, be smoothly let out (but quick still). There's no reason to give it gas before the clutch is out on up shift, but right at the point of engagement is ideal. You should never be close to "riding the clutch" as you upshift at 5 or 6k RPMs. SRM should have no impact on when or how long to "clutch" during upshifts. SRM during upshifts just ensures the RPMs are kept steady, and is only noticeable if you're a slow shifter. - Depends on how you're downshifting. If you're downshifting to a stop, speed change, or upcoming turn, there's no need to give it gas until necessary (speeding back up). SRM will make the downshift smooth by keeping RPMs stable during the shift, instead of a normal car where your RPMs may jump from 2.5k to 4k during a downshift, causing an uncomfortable jerk. If you're downshifting to speed up or get out of a sticky situation, the clutch and gas pedal movement should be similar to an upshift...quick and smooth.

Used it all the time when I first got it, but in daily driving I kind of hate it...reason is because at the top of a hill I always go into neutral and every time it revs up like crazy. I have no trouble matching downshifts for a gear or two (4th/5th to 2nd is kinda hard to get right) so I only turn it on if I know I'm driving with a little more spirit.

I believe the SRM actually robs potential torque (and maybe some HP) when its 'ON'. The reason I say this is because I have noticed whenever I used it that the car has a noticeable decrease in throttle response and makes the performance feels overall sluggish. I SOTP tested this out on at least a dozen occassions and I am almost positive this is happening. I wish there was a tangible way to determine if having SRM 'ON' actually is doing something to the engine output.

Its an awesome, very unique feature. I use it all the time. Great in traffic or out on a twisty road by yourself.
Not its real purpose but one of the little things that's cool is the little 'grunt' rev it gives at low speeds when you turn into a parking lot or something. Inside the car it sounds real cool. outside? don't know or care, I'm inside the car.

I usually drive with mine off. It just seems to make my upshifts herky jerky in daily driving.

I love the SRM, I left it on for most of the first few weeks of ownership. Then I turned it off and realized how much it spoiled me. So now I only turn it on sometimes, like the weekends.

I've had my car almost a year and a half and have only turned it off a few times. I love this feature. I've been looking at the new Mustang GT and the lack of SRM is one of the things that would hold me back.
