Question about rev matching
 

Hi guys. So first I should say that the 370z is my first car w/ a manual. When I got used to using a clutch, I turned off SRM to I could teach myself how to rev match.

After a while, I noticed that when SRM is off, my throttle blips are not as responsive as I would like, but when SRM is on, the engine revs perfectly. I'm perfectly prepared to attribute this disparity to user error, but I have to wonder... is this just a characteristic of the stock car I have to accept or am I doing something wrong?

On a related note, with technology such as SRM, why didn't Nissan equip a lighter flywheel?

Anyway, I don't want this thread to turn into a toxic thread, so I will not respond to Z-bashing.:tiphat:

Throttle lag is something of a common complaint on the forums. The flywheel is heavy as well. I've found that I need to blip it a little harder than I initially expect in order to get a smooth gear change. After a while you'll have it down to muscle memory and it won't feel as awkward. keep practicing.

just use synchrorev match, your car has it, downshifts are just one less thing you have to worry about

Still something worth learning. Not every car has it - in fact I don't believe ANY other car has it.

Rev matching manually adds to the driving pleasures of an MT IMO

Porsche stole it (911 and new Boxster/Cayman), BMW (5/6 series) and the new Corvette... It's starting to spread but it's really only being used on the high end performance options with the Porsche's.

Even the Genisis has it in their R version. When I test drove it without knowing about it, and nobody explained it, I felt stupid like never driven a manual before. Really annoying feature I thought.

With electronic throttle control still enabled:

SRM = fast revving because it doesn't use the throttle tables, it directly acts on the throttles

SRM Disabled = uses throttle tables, has processing lag + weird curve in stock table making it much slower to bring up the revs.

Disable ETC and the response is much faster, but even then it's hard to match SRM's speed.

I'm surprised it took so long for any car maker to come up with rev matching. To the OP, I've owned quite a few manuals over the years and never concerned myself with any rev matching per se. I only see a benefit in SRM if you track your car. Remember, SRM=heel and toe except it's done automatically.

Thanks. This is what I was looking for.

Intakes should help throttle response. 3rd gear for me is the most fun to rev match. 2nd and 1st take a second longer on the throttle if at higher speeds. I don't use SRM because well, my Camaro is auto with paddle shifters. To me, that similar enough to SRM rev matching. I like it old school! :p But if I am going to the track or corning hard and fast, I will use SRM because while I know how to heel-toe, I am not perfect like SRM is.

I'm so confused

uhhhg.. trottle lag:/

Siorry bruh... I feel your pain. My first Z was totalled after 9 weeks. Dealing with that is a bitch. I hope it works out for you. :tiphat:

Was there anything regarding SRM overheating on the track? Or is there literally no difference compared to doing it yourself minus the human error?

Lol, are you replying to the wrong thread?

Some say it can be harder on your clutch/tranny because you pay less attention to how you shift, but on paper, there's nothing to overheat vs normal method of rev matching.

Was gonna say.. dafuq are you talking about

Totally agree. I do use SRM when I am on the track but everywhere else I manually blip the throttle. I do have a lightweight flywheel though but didn't really have problems even with the stock one.

I use it on the track as I can't heal and toe very well on my 370z. Actually the only car i could ever heal and toe well in was my 78' 280z.

Yeah it's really hard for me to on my Z as well. I'm going to have to re-locate the accelerator pedal because of this. The pedal is too far below the brake pedal at anything other than 100% maximum braking effort and my foot just can't reach the gas. I'm going to shim the gas pedal towards me a bit, maybe even scoot it to the left just a touch. We'll see.

Me too. I was very drunk when I wrote this. :tup:
