SRM: Who has it and uses/doesn't use it?

chops

sorry to bump an old thread...but id really like to see this poll taken by others. ive been driving with SRM off for the last 100 miles or so. at first when i turned it off, i realized how lazy and SLOW my shifting has become. i will shift and the revs will drop too low and ill jerk back, but once i go back to shifting like a non SRM car, then my shifts are smooth again! ive totally become spoiled by SRM (since it holds revs between gears)

however, once going back to SRM, ive realized its kind of a pain to have on...i mean aside from the simple, idiot proof downshifts (my first downshift with SRM off lead to a jerk...totally forgot to rev-match). with SRM on, ive come to not really like the fact that it holds revs between gears. my shifts have become jerky with it on now, as the revs are not dropping fast enough, so its jerking forward.

who else has experienced the difference in driving with SRM on/off?? i ask because i feel that if i get into another 5mt/6mt, i'd be embarrassed at how jerky my shifting is, thanks to the SRM making me a lazy shifter!

I've been wondering about this lately, whether it is an SRM thing or a clutch thing. I still have not been able to get perfectly smooth FAST upshifts. It's perfectly smooth if you wait for the rpms to drop and then ease out the clutch slowly, but I haven't figured out the secret for smoothing out faster shifts.

yes this is the SRM doing its thing. as you're shifting the revs are being held in place, so in low gears where the difference in RPM is greatest, you'll have a jerky shift if you try to shift quickly. unless of course you're on the throttle. as others have said...if you rev high, that manual shifts silky smooth! otherwise with SRM on, you need to hold the clutch in for an extra second or so in order for that rev to fall

You can also let go of the gas first, then shift. The engine will not hold the revs this way, and it will be smooth. I drive like how you described it though.

I find shifting to 2nd when I hit 3000 RPM works best for me with no jerkiness if you ease off smoothly and give some gas into 2nd.

I leave SRM on because I'm new to M/T.

I leave it in, but I hardly ever hear or feel the engine rev.

I didn't buy a car with it, partially because I didn't see any real benefit to it. I mean, there is some, but I think it helps develop bad habits.

I don't see it as any particular advantage or innovation.

There's probably an advantage in that most people would run a lap faster with SRM than on their own, but it doesn't do you much good to come to rely on something that for the time being is more of a gimmick, in that it is not commonly used.

LOL that this thread has been revived. I read my OP and was a little embarrassed I ever asked this question!

I've found the car loves fast upshifts when you're heavy on the throttle. Run that baby up towards redline and the MT just sucks itself into the next gear as you shift. Try to shift quickly when driving slowly though and it's not going to be pleasant. Lately I've had SRM off as I like the added task of rev-matching. However, it's going right back on during my autox or track days.

Day to day driving I use it. When I want to go out for a spirited drive I typically turn it off.

I have only used it one time and that was on the test drive, until I figured out how to turn it off. It took a day or two to get used to shifting the Z, but I've been fine since.

I like it when I am going out for a weekend drive to have fun. Otherwise I have it turned off mostly since the car serves as a daily driver for the summer. In traffic or around town its just overkill and not needed. Sometimes I roll the last 20mph with the shifter in neutral and the car revs for about 5 seconds before it figures out that I am not going for 2nd gear and just coasting.

In stop and go traffic it behaves badly sometimes.

This is the only aspect of SRM that bugs me. The system should be smart enough to drop the revs if you've released the clutch (thus clearly not planning to downshift).

Actually I picked up a bad habit from my dad when he taught me to drive, and I find my wife doing it too. When I shift into neutral like that I wiggle the shifter back and forth and then let go. Kind of like making sure its in neutral. Its just a habit now. If I do this the car goes crazy because it has no idea if I am going for a 4-2 downshift or a 4-5 upshift.
