Are you guys always turn on SynchoRevmatch on daily driving?

lemme use this opportunity to ask you guys about your synchrorev matches!

so in my car.. when I downshift/rev-match myself.. the car is smooth and there's no shift-jerk. but for some reason my synchrorev isn't that smooth. it feels like.. the car blips the throttle for me, but not quite enough.. so I still get that engine-bog/unstable feeling when I let the clutch out.

I don't think my S-R system could be faulty since the car is pretty much new (plus it 'does' rev) but I haven't experienced the 'magic' of the revolutionary system like all the reviews/members rave about.

do you guys 'quickly' release the clutch after you downshift and it revs? I think maybe it's because I slowly let it out thinking it'll be a smoother shift, and in those 1-2 seconds the revs drop a bit?

I don't know why you get the jerk downshifting. You can always leave the negative battery terminal off overnight see if that resets it.

As for the bold paragraph, that's what you are SUPPOSE to do in a 6 speed gearbox. Slowly let the clutch out for a smoother up shifting. I did that in my 350z. BUT with SRM on, it will hold your RPM during upshifting. Next time you drive your car, try this. Shift from 2nd to 3rd gear (could be any lower to higher gear) ---> but keep your clutch depressed to the floor ---> you'll see that the RPM will drop and STOP at the desired RPM for that 3rd gear. YOu still have another good 2 seconds and then SRM start to let the RPM drop beyond that point. So for smoother upshifting with SRM, your best bet is to upshift, wait for the RPM to drop (and stop at the specific RPM), then let the clutch go. You can even let the clutch go very quickly but it won't give you any jerk or shiftshock as your RPM is kinda stopped at the desired rpm. lol I hope it makes sense.

In the past I always heel toed. When I first got the car it was a feature that I used once in awhile. I can mimic the rev match naturally but I do not remember when it is on or off so I let the car do it and it's off, or I do it while it is on.

Now it is on all the time and no more doing it "together".

RE: do you guys 'quickly' release the clutch after you downshift and it revs? Yes.

here's a video kinda explains the upshift RPM holding:

Sometimes If i'm driving lets say 4th gear, and I wanna rev at a friend of mine who's driving next to me, all I do is clutch in ---> full rev---> still clutched in -----> RPM slowly drops and STOPS at the desired rpm for 4th gear ----> it'll stay there for a good 2 seconds before it drops it beyond that point. then I quickly let the clutch go. No jerk.

yeah.. the upshifting with SRM is all good. but the downshifting, after it revs.. that's when I slowly let the clutch out. I thought maybe the revs were dropping in that time and that's why I got the shift shock. but no.. it looks like it should totally hold the revs steady till I release the clutch regardless.

maybe I'll try to reset the system and see if it helps any. otherwise I'll go to the next Z meet around here and compare with some of the guys to see if I need to take it in since I'm still under warranty

I haven't driven another SRM car for comparison.. maybe I should go test drive one and see if there's a big difference hehe thanks for the tip dude!
