Cruise Control
 

Hey guys,

I just realised again this morning that the car has cruise control and its something that I literally never ever use.

Am totally new to modding and I've noticed people saying that there aren't much gains to be had from weight reduction (cons outweigh the pros - especially if used as a daily driver).

My questions,

1. Are the cruise control mechanisms heavy? Any point doing a delete?

2. Would it be expensive/difficult to do?


Thanks for advice!

Cheers,

Damien

It's just the plastic lever. The rest is in the computer. Is not like older cars where it had to actually press in the gas pedal and throttle cable.

Brilliant, thanks!

WELCOME to ..... The Forum ..... :)

I'd just leave it in place. The next owner may want it ..... ;)

It's handy in 30mph zones when there are speed cameras or cops about... Actually it's handy in any zone when there are speed cameras or cops about. Also it may produce better economy when cruising, I haven't tested this though.

Anyone know how to keep it on after restarting car?

I think that's a safely feature you can't alter.

It does not in my experience. If you're like me and you like occasionally rolling into the throttle and seeing 90 or 100 it'll probably help your economy. But that's just lack of self control. lol.

Never seen that on another car. Annoying

It's not really that difficult to press the button tho. Right?

No not really. Would just be nice to just leave it active

I won't lie, on interstates/long open roads. I get WAY better gas mileage using cruise control lol. But, like moose said. We as humans can't decide exactly where the throttle should be unlike the computer. Much less hold it consistently.

Combustion engines operate most efficiently at steady state operation: constant load, same throttle position. Accelerating uses a lot more gas than maintaining speed, and I don't know about you guys but for me it's a very concentrated effort to maintain a constant speed as I cruise along, there's no way I can maintain that over a >30 minute stretch of boring highway or commuting and that's where the cruise control kicks in.

Where it may not work so well is elevation changes, going uphill is an increase in load so the cruise control opens the throttle to compensate when in reality it may be best to allow the car to slow or downshift which is likely more efficient than the engine struggling in too high of a gear. There are instances of certain cruise controls getting flummoxed by hills and hunting for gears in automatics.

Cruise control is great for driving efficiently and has definitely saved me a few bucks. Set it to 65, get some entertainment on the radio, relax and keep my eyes on the road. Yes it's boring but not every hour+ long trip can be turned into a 3 hour detour of

and avoiding speed traps.

Agreed. Whenever I hit the highways, I put it on. I think the car does a little bit better on gas this way, and it keeps my speed from wandering due to not paying 100% attention to the speedo in hilly areas. It saves me from getting pulled over when some cop is hiding in the bushes around a corner at the bottom of a big hill trying to bust unsuspecting drivers. Also, it lets you relax your feet and change positions a little bit, which I find nice for longer drives.

It's true. In my Integra I would get better gas mileage manually hypermiling than using the cruise control. Perhaps one day when I am better at driving this car things will change but for now the cruise control saves me gas.

This probably affects my answer. I live in the foothils of the Smokies. LOTS of elevation changes. So if you live in flat land area or a less mountainous region, then you may see a significant increase in mileage.
I drive my car like a bat out of hell and I have never reset the Avg. MPG setting on my dash. 13,000 miles and a couple days of REALLY spirited mountain roads and my car averages, since day one of ownership, 28.6 mpg's.
I've used my cruise control maybe 20 times and always on the highway. I do live in Georgia though. Home of the worst fu&*ing drivers on the planet. So cruise control is rarely an option.
80+ mph on the hwy-ALWAYS, 55-60 on the majority of surface streets-ALWAYS.
Hope any of this helps.

We really are a bunch of horrible speeding know it alls in Georgia lol. I honestly hate driving around here. For the simple fact it's like going to war everytime you get in a car.

I try and stick to pure back roads other than my commute to work

This. I speed because racecar. I've always sped tho. The worst part is the friggin "Oh look, someone's walking down the road, minding their own business. Lets all jam our GD brakes and see if we know them or can hear their thoughts."

MAkes me hate Ga. That and the heat.

Cruise control kept me from getting my license suspended back in the day - so I just kept using it on my vehicles. It's way too nice to rocket along and thanks to the limited insulation, I can't even claim I didn't realize I was going ninety; I knew it and just didn't care! :D

And yeah - it's a must for long road trips.

It is nice that the new systems are so much simpler though. The only thing I miss from the old vacuum system cruise controls was being able to use it at low speeds. I could set the cruise in my Celica as low as 20 mph, which is great for the little speed-trap towns.

How low can we engage ours? I've used at 45 today

It goes down to 25mph

I almost never use cruise control....but that said after about 4 hours on the freeway it comes in handy when ya need a quick stretch of the right leg ;)

Mine doesn't set below 30 (I'll have to try again now) - I wonder if there's a difference between auto and stick?

The stalk for CC is the same in all modern Toyotas. Had the exact same thing in my two prior Tundras. Every manufacturer does it a little different. Some have clicky switches, some have soft buttons (Toyota, Ram, Mercedes).


Why are you trying to use CC at such low speeds? What drove me nuts was in my GTO CC wouldn't set above 80 which blows in California for long highway drives.

I just set mine at 20.....

I forgot all about that in the GTO. Of course, 81+ in Ga will get you shot.

Crazy. What gear were you in?

3rd. Just did it right now. Won't set at 19. Must press up on stick

Well there you go - learn something new every day! :D

Bump to add:

Ok, this has me curious. I went out and tested yesterday in different gears to be sure. My cruise will absolutely not set lower than 24 mph.

I wonder if this is something set in the computer somewhere that can be changed?

Ruining OFT stage one fwiw

I wonder what the max that you can set it to in the BRZ/FRS is. I know my Outback won't set it above 90. (Not that I'd recommend trying to set cruise at 120, unless you live in Germany, but still...)

Every time I jump on the highway, I accelerate up to 115km/hr. and set the cruise there.

Definitely does. Especially when you are driving on an incline.

I've had the cruise control set to 220 km/h (~137 mph) in my GT86.
Boring German autobahn.
