Software only. I had rev matching added to my Subaru. Tuner connected his laptop and 30sec later it was done.

I'm hoping there'll be a software patch for the Ford for this. How tuneable is the Ford ECU? Once we'd installed ECUTEK on the Subie you could do anything to it.
i doubt it's that simple - on top of software you need sensors on clutch pedal, gear shift and transmission - the cost also includes the time to develop, implement and test as well as support and parts warranty.

my guess ford took the numbers and considered the amount of
sales with manual transmission + possible revmatch option < vs > time and cost of engineering and implementing

Hey guys, I'm curious as to why the new GT350(R) does not come with rev-matching on the 6-speed manual. Chevy, Nissan, BMW, and Porshce all give you rev-matching with their manuals. I just find it a bit odd Ford would leave this off the Mustang, especially the GT350 where the rev matching would be really helpful on the track. This feature would also make the car easier to drive in traffic.

Anyone else want rev-matching?
Z/28 doesn't have Rev matching. Wish it did, because it is a very nice feature. It works well in the new Z06. Even a 4th to 1st shift was flawless.

The real question is whether the GT350 will have the dreaded CAGS 1st to 4th lockout to get a better mpg and gas guzzler rating.

Z4M, coming hot into a braking zone. Threw it in second and the rear just spazzed out on me. Pretty sure my heart rate spiked right there... I learned about heel toeing and was obsessed with practicing it whenever I got a chance afterward.
Now I understand - the rears were going a different speed than the car, not locked. I've been there many times in the snow and ice. Things do happen more slowly on ice compared to racing on pavement so the pucker factor is lessened I'm sure. It definitely teaches you how to be smooth with the car. :)

One thing Ford has done that I have mixed feelings about is engine braking is much reduced on modern cars compared to a V8 from the 80s, for instance. You can just let the clutch out and while it upsets the car, the effect is a lot less than it would have been. It's a convenient feature for reducing bucking at low speeds as well, but I liked having more control of the car. I suppose it's an IAC programming thing that could be tuned out. With the reduction in engine braking RPM matching is much less critical.

Thinking about it, the lack of engine braking probably also improves engine durability. The peak load on the rods is going to occur either on compression or as a stretching load on the intake stroke. Less engine braking will reduce this stretching load on the rods and could be a key factor in the durability of engines like Coyote and Voodoo.

Didn't mean for my response to sound like trolling. Sorry if I offended any one.
No offense taken. It's jsut that you are literally the first person I've seen on a forum who liked the hill assist feature. I therefore thought you might have been kidding.

As far as heel/toe goes, it is very useful in the track. Not required, but it makes you a much smoother driver. If you rev match without heel/toe then you will need to come on and off the the brake, which can make it more difficult to balance the car.

Point is, including this feature is the best of all worlds for a manual driver. It lets you do it on your own when you want, and it can provide assistance when you want. The downsides are minimal.

Thanks for the links. This product looks like a good first step, but because it is sensorless it must make certain assumptions about the shift pattern that probably wouldn't fly as an OEM solution. For example, this probably assumes that you are downshifting one year at a time, and would require a clutch release after each shift. In any event, pretty cool device for certain applications.

Thanks for your response. I appreciate it and I really do like the Hill assist feature.

I've never had the opportunity to drive a car that had the rev matching option. But from what I'm reading, I'm sure I would like it as well and can see the benefit. :thumbsup:

Have a think. All the hardware is there.

Sensor on the clutch to disengage the cruise control.

Sensor on the brake to light the rear brake lights.

Drive by wire control of the throttle by the ECU.

Software tells the ECU to blip the throttle by 0.4 sec when the clutch is engaged after the brake and the RPM is above 3000 (for example).

Probably takes some junior software engineer until morning tea to write.

way more than that, all tire speeds are known. brake pressure of lack of, throttle pos, yaw, steering angle.

really all the info for rev matching is available.. some might claim that tranny sensor is needed, but ecu can do all that by rpm vs tire speed.

great insight - why do you think ford didn't implement it ?

If its programming and all the sensors are there then its a feature you can possibly add to the car's ECU via a custom tune.

Ford's main concern would be the Fun Police with law degrees.

As I said I've got this feature on my Subaru (via a software patch with my ECUTEK opened ECU) and you do need to be very positive with your clutch actuation. Once you start to depress the clutch you must do it quickly and cleanly otherwise with the throttle blip will shot you forward if the car is still in gear.

It's designed to blip the throttle as you change down under brakes, but say you've applied the bakes to slow down at the lights and then just touch the clutch without fully depressing it the car will suddenly accelerate into the car in front.

It could be a feature normally turned off and needs to be selected or better still only works in race mode or similar but can be disabled for driving in traffic.
