Yes, snow tires...for cold and snowy climates. Who knew?

Not that much snow in ny this year

True - same here in S. Ont.
Winter tires aren't just for the snow. They remain pliable, providing maximum traction in cold weather, while at the same time an A/S or summer tire starts to harden like a hockey puck.

yep thats because they dont have a steel sidewall like regular summer tires have providing for a softer sidewall aka more flexibility aka more traction when cold/hot.

When i had my evo (before i bought slicks) i would throw my snow tires on when i went to the track for the added traction.

I stand by bridgestone Blizzaks...unfortunately i havent had a reason to put them on this winter since its been fairly mild in NYC, just last week our temps were below freezing but for the majority of the winter we've been above 34*..

Don, I don't understand your point. We had an 04 G35x, and the manumatic in that car was a POS compared to the ones in the newer G35s. You downshift and the whole thing just shakes and the car just goes BUAHHHHHHH as it's coming down in revs. With the rev matching, it is smooth, fast and you are ready to get back on the throttle immediately.

Your point makes absolutely no sense. Theres a reason your alone on this. It is like someone coming in here and bitching about how their wheels should be square and not round.

Please answer the question asked above. How do you rev match an automatic yourself? I would like to hear an answer as well since it doesn't make any sense.

The thought of the computer weighing whether or not if I deserve a downshift, and if it felt like it, definitely made my day better. haha


I started driving on a '98 Infiniti i30. Regular automatic, but I did drive it unconventionally, aka downshifting. Basically what I did (at first) was stick it into a lower gear, and let the tranny make up for the speed difference. It didn't like that, and until it was flooded out by Sandy, it had a bit of a transmission slip from 2>3 cause of it. After driving my G with the DRM, when I was in the i30 I started doing it too. There were two ways of me doing it, either anticipating really early and flooring it to get it to downshift on its own then locking it in that gear with the shifter, or simultaneously while pulling the shifter into the lower gear, I gave it a throttle blip which helped the engine spin up before the tranny locked so that it was closer in RPM. I had a pretty good system, it was a 4 speed so one and two were positions on the shifter, if i turned off OD it would go into 3rd, then normal mode was 4th.

Granted, this was a cable throttle car. On the G, its not too noticeable but I know that it cuts the throttle when shifting either way. On upshifts, you can kind of hear it get off the power and then get back on it (mainly at lower throttle positions), and downshifts it takes over the throttle to DRM then gives you control back once the shift is completed. OP might not like it as much, but theres no doubt that it saves your transmission a tremendous amount of stress.

Though I don't agree with the OP, I will say that you can rev match an automatic. I have rev matched in a 2000 Honda Accord and a 2005 Honda Accord. Pretty much, you get used to the timing of the gear changes, that in between the shifts of the gear sets, you can blip the throttle. When I did it, about 90% of the the times I tried, I would miss, but the other 10% it felt like a true rev match, which did feel different than not doing anything.

What I don't get is why the OP doesn't like the downshift rev matching. There's no reason NOT to like it. Furthermore, I skimmed that people were saying you don't rev match if you want to engine brake, but without bringing the revs up before downshifting, how do you use the engine to slow down? You're using the decreasing rotational momentum of the engine to slow the car down.

My opinion may not matter, I test drive my V, messed around with the paddle shifters, and enjoyed it. Felt better than the 09 max shifters. You test drove yours, liked it and purchased it. Now you found an issue. You plan on continuing to drive it or trade?

If you think about it, with all the sensors and electronic controls, about the only thing that was still entirely up to the driver was the steering and braking. On the new Q models, they've implemented some sort of steer by wire (with a mechanical fail safe). One step closer to self driving cars.

I love the rev matching, even more so in the Z but I love it in both cars. I really don't understand your comments as I think it gives you even more control than an auto with out it. It definately took me a while to learn to use but once I did I think it gives you an amazing amount of control.

DonVonG

tires square not round? are you really comparing that to a feature which is NOT a necessity? Tiptronic transmissions have been around alot longer than automatic rev matching. It is a FEATURE not a REQUIREMENT.

When i am downshifting to slow the car down i wouldnt rev match. I would downshift and let the resistance of the engine slow the car down. I would not give the engine fuel to increase the RPMs to decelerate. When i drove a manual i would not rev match if i was downshifting in order to slow down.

When engine braking you are using the friction of the engine to slow down. The engine RPMs slow after a rev because of the internal resistance. I may have read your last paragraph wrong, but in my eyes i would not give the engine fuel to spin faster if my goal was to slow down.

Just like it took you a while to "learn to use it" i have mentioned multiple times "I just have to get used to it i guess" I am coming from driving a manual car without features like rev matching. I guess with time when i learn to use it i might begin to love it as much as you do.

A circle wheel isn't a REQUIREMENT either. You could technically drive on square wheels DOOD.

Rev Matching is also designed to SAVE the transmission from excess wear and tear you newb. Any 03-04 G i'v driven with over 100k, clunks in manual mode. The 05-06s with the updated transmission that include DSRM don't do this.

How on earth you think the tiptronic modes that engine brake and aren't smooth is better than a quick downshift is beyond me. I think you need to reevaluate what is ACTUALLY better because I don't know a SINGLE SPORT oriented car that dumps a gear without matching the revs first. Seriously. Any BMW, Audi, etc, is going to rev match. So your 'expectations' are completely ridiculous.

Don, seems to me brakes a lot cheaper to replace than piston rings. You use brakes to slow down, engine to accelerate. Be in the right gear for a given speed at most [all] times. The latter isn't really applicable to an auto as it is in the right gear most of the time on its own.

If you downshift without rev matching a manual, you can't quickly let the clutch out. I suppose you can, but not without harsh drive line shock. Since you're now slowly easing the clutch out while the engine rpms catch up, clutch wear is greatly accelerated. I can understand using some engine compression at this point to slow/adjust your speed.

I really don't understand your driving style. Why not use each system for its intended purpose....
