Rev Matching

[Schilling]

After watching a lot of the laguna seca videos, I'm wondering if it's a standard feature on the GT350. Has anyone heard anything lately?

Rev matching is not part of the GT350 or the GT350R. What you are hearing is driver mod.

I wouldn't even call it a driver mod. It's really the way many or even most downshifts other than those done at the slowest speeds should be done.

Never mind that the practicing you get on the street will make rev-matching at the track second-nature . . . it'll become as natural a part of downshifting as moving the shift lever. Trust me on this.

Watch this Vid around the 8 second mark, You can see the driver Blip the throttle before down shifting. It appears that the pedals are setup so rev matching should be easier.
But if Auto rev matching is your thing, The 2016 Camaro will have it.

I rev match all the time, and love doing it. It just takes time, try this rev match first gear if you going 10 mph or less, you might have to slip the clutch a little bit more. 2 gear for 20 mph, 3 gear for 30 mph, 4th gear for 40 mph. Try that on an open road with no traffic. Each time you rev match at the exact speed and specific gear, give it about 1,300 RPMs. Remember Clutch pressed, shift into lower gear, has you rev to 1,300RPMs simultaneously depress the clutch (let off) and see how that feels. This car is great compared to my 2013 Camaro manual I use to have. Remember rev matching has to be done fast so that you keep your momentum, speed and not cause jerking.

Good video upload, yea I remember seeing that to, their configuration might be better for heel and toe. I bet once he learns how to rev match he will enjoy the car more and feel a sense of pride, I know I did. That also will helps if he drives any other manual trans car and increase proficiency. :cheers:

I was a city boy all my life drove automatics all the time, when I went to Germany it chanced everything. If I can drive a V8 manual in the city and country roads and rev match like a champ so can you. Master the car you are the drive that's what a manual trans is all about. Manual (Manually, automated, naturally, uncompromised, automobile logic.) When you drive one everybody knows. :ford: Also rev matching is a computerized function, I rather dial the torque I want. The computer might have limitations on what it can give out.

I wish the GT350 came with rev matching and I wouldn't be surprised to see it in 2017. I've been using an Auto-BLiP on my GT for three years and it works very well.

So long as there's a way to turn it off, and to do so without the ridiculous fake paddle shifters like on the C7, then they can add rev-matching without any objections from me. Since the line-lock option is already there, why not rev-matching?

Personally, I prefer to do it myself and get the satisfaction of full control over the car. But for someone who's trying to make a record lap run and wants to focus on line and braking points as much as possible, I can see the desire to have the car take it over.

Corvette C7 had rev matching with the manual trans and I didn't like it . Wasn't smooth and never really liked it Most of the time it would over rev and cause a jerking motion. That's why so many Vette owners are jerks. No I'm just kidding.

Put my shifter in S. The auto rev matches with ease.

Not sure whether you are really talking about rev-matching, or just heel and toe down shifts. Typically the way I understand it - the goal isn't really to MATCH so much as get the revs up a little so that you upset the car less during turn in. Typically though you want to complete the down shift prior to turn in, correct?

I haven't done heel and toe down shifts since I went away from Fox Mustangs to the newer Mustangs (~5 years or so). Unless I am braking exceedingly hard, I can't get my foot to reach the gas pedal. The Fox Mustang pedal setup was much better (about the only thing in those cars that I can say is better than the new Mustangs). The brake and gas are just too far apart in my 2015 for me to do it easily in everyday driving. I am buying some aftermarket pedals to try to improve this. It never seemed like a big deal to me in the newer Mustangs, because they have almost zero engine braking. If you downshift without getting some revs into an older, high power engine in the Fox Mustang - you are asking for trouble! With very little engine braking, then the only reason to do a heel and toe downshift is to go easier on the transmission, which I'm less concerned about. I just let the synchronizing components do their jobs.

I was never very good at doing heel and toe down shifting anyway. I can never keep a consistent pressure on the brake while hitting the gas pedal. Doesn't bother me when I'm alone, but I avoid doing it when I have a passenger. Any tips?

Rev matching is part of heel & toe, not the other way around. It is the part that does not involve the brake pedal. The point really is to get the revs matched, at least close enough that you don't upset tire grip or have to slowly engage or slip the clutch to avoid any lurching.

Sorry, but I have no heel-toe tips. I agree that the pedals on the S197 aren't placed very well for doing it. I haven't been able to find a do-able right foot placement or movement that doesn't risk spiking my rather grippy Carbotech track pads into suddenly biting really hard (I've had a couple of surgeries on each knee, for whatever that's worth).

Really? I have no problem heel toeing on my Boss. It's worlds better than on my Focus ST which even with leveling the gas pedal is still awkwardly positioned. I tend to heel the brake and toe the gas though.

It's a great skill to have though. I'd recommend making it part of your right turn brain procedure. Once it becomes second nature, you don't even really think about it on track.

I had rev matching in my 370Z it worked rather well and had an on/off button for it. But I will say it's better to just learn to do it yourself. The 370 only knew one way to do it and that was in a racing situation. Which isn't a bad thing but if your just spirited driving your timing may be different. For example when your racing your coming into a turn quickly, shifting and braking quickly then powering out. So the auto rev match works great in that situation bc as soon you come out of the gate and it even thinks your going into a lower gear it blips that throttle. But I often found during normal spirited driving maybe your coming down an off ramp but maybe don't need to hit that down shift so fast, sometimes I'd hold it in neutral before I decide what gear I'm going to select, in the Z it would blip at that moment and I would end up having to rev match on my own anyway. Does that make any sense?
