Disabling the Rev Match feature

[m3incorp]

I have a slightly different take on Rev Matching and Hill Assist. I've driven manuals since the early 80s and did my own rev-matching. I know I have the skill but I allow the car to do it for me now. Throttle linger while upshifting used to bother me, but when I am getting into the speed fast, I don't mind that it maintains the upper rev range, expecting to keep me in the horsepower/torque band meaty part in anticipation of an aggressive upshift.

For the hill assist. I typically turn it off except in one area where there is a super steep incline at a stoplight. This light is the exit of a Walmart and Sams Club. When stopped at the light, the cars pull right up to your bumper. In this case, sure I could most likely start without rolling back an inch but I figure the driver behind me is watching the light turn green and already moving forward, which leaves absolutely no room for any rollback.

Given the right situation, I find both of these features to work fine....and yes the brake does take a bit to let go when hill assist is engaged but you don't roll back.

In situations like that I use my hand brake.

The biggest help for newer drivers imo is the anti stalling thing but if you get too used to it or only driven a car with it, the chance is greater that you'll have issues if you drive an older car without it.

True words. My Mustang recently went into limp mode with a wrench on the display (fortunately it seems to have been a non-issue), which also disabled various features. I pulled over to the side, coincidentally on a hill, to stop and restart it, and stalled the engine on my first attempt. Gotten so used to the anti-stall feature now that it took me a second or two to figure out what the problem was and position my foot on both the brake and the gass before trying again. ;-)

why are 'car people' scared sh*tless about dragging the clutch? You can sit there for 5 minutes at 1200-1500RPM slipping the clutch trying to drag the car forward against the parking brake and it's not a problem.

On my 16k manual 2000 Escort myself, brother, friend, and his GF all learned stick on the same clutch. After many track passes, 65k Miles and 7+ years the clutch was still perfectly fine.

Meanwhile people act like the clutch in a 45K Mustang will burn up at the slightest slip.

Perhaps, but it seems like unnecessary tear and wear to me. Also the clutch starts to smell funny if you do it.

I wasn't advocating you do that often. I was simply illustrating for effect that 'hanging' your car on the clutch on occasion is not something to be afraid of. And indeed it should be a skill you can do on demand. Dragging the car momentarily forward against a hill and the parking brake is a fundamental skill of driving a manual. Hill Start is thus rendered immaterial and superfluous.

I'm sure it has it uses (it was also part of my driving test a long time ago), and it's easier to do it that way than via a light "heel-toe"-like application of the right foot. It's a bit of a drag having to engage and disengage the parking brake while momentarily stopped on a hill, just to be able to start driving again though.

Not the same thing.

Rev hang is something that gets in the way of smoothly driving a MT car, and really isn't a good thing at all (we're just stuck with it for emissions reasons). In particular, it's not good for the synchro for the gear you're about to select (most likely 2nd), as it either makes the synchro work harder to get everything rev-matched (what synchros do) or it encourages you to 'beat' the synchro by basically cramming the next gear into engagement (making you do a weenie version of a power shift every time that happens)

I really think this fear is overblown for anybody with much MT driving experience. Rearward vision in recent car models has been such that the car behind you is not as close as you think it is. Courtesy of high trunk lines, and not just in Mustangs.

My parents drove stick when I was growing up and in Japan the at-grade R/R crossings have steep slopes and there are many thousands of such crossings so it was totally routine.

I don't doubt that you are correct

Edit.

I want to edit my response because it may have not come across the way I intended. There a lot of experienced people on here that give their advice or make statements; those people typically have a way of explaining why they made a statement or give certain advice without belittling others. There are also a lot of people on here that look for advice or opinions from that same kind of person. There are some that don't believe in any kind of change but they usually don't relay very well why the change can't be a positive thing.

End of Edit.

I drove mine in a Christmas parade and definitely had that funny smell. With that having been said, I have no problem dragging the clutch if it is necessary.

What gets me is when everyone thinks everyone else has to do everything exactly the way they do it.

Different strokes for different folks and most likely for different reasons.

Perhaps, but it seems like unnecessary tear and wear to me. Also the clutch starts to smell funny if you do it.
