the theory is that with the cruise activated you not doing as much when driving such as looking at the speedo all the time to check your speed cos with the cruise you know its what you set it at hence no looking up and down every few seconds.....

As a truck driver I know that it makes it a hell of a lot easier to do the long trips!!!

Reading stuff like this makes my blood boil!!!! As a truck driver I know you MUST check everything all the time.

There are thousands of "experts" who continually remind us that we must concentrate when driving, no eating, no mobiles, no radio, no smoking... the list goes on and on. Yet the concentration of our driving public is getting worse. The more aids we supply, it seems the less concentration of the driver.

OK when I started driving, we had trailer brakes and truck brakes(no foot/hand combination), 24-speed quad box(2-gearsticks no synchro), 250max Hp, even had a mechanical hand on the door. Yet with all this action in the cab, we could dodge potholes while seeking out the smoothest part of the road ahead, watch the load, check mirrors.....

Now at 57 I can go outside, walk my excavator and take a swipe with the bucket while slewing. Not superman, just practice.

Education is what's needed, not gimmicks.

Some info: Cruise control can't see that big hill coming up. So if you wait until it drops into its operating range, you're down a gear before you know it. You MUST help it by booting it into the hills.

Sure it's great on the flat, but all this bulltwang about better economy is only from drivers who can't maintain a constant speed.

We've all seen them, 80 on the highway, 120 on the passing lane, I guess they need all the help they can get.

or you need a more powerful car.

I don't need to help the cruise control in my r33 by booting it into hills, it maintains speed just fine, maybe gains a bit down hills, but not much.

I believe it improves safety as when i have the cruise it takes a lot longer for me to get fatigued, which in the end leads to lapses in concentration.

It should not be used on country back roads when things can pop out at you, but on a dual carriageway freeway i dont see negatives to using it.

Too true. But seriously, get in an ordinary como or a falc and let them run at a hill with cruise on. At the top of the hill, check where the accelerator is. She'll be flat to the floor. That's not economical driving.

I get so sick of following shit boxes on cruise. You'll see them drop back to 90, then slowly pick back up to 100, then roll down the other side with the brakes on. You can really notice the stink from falc's and camry's running megarich.

All this in an energy conscious age.

Like I said, great on the flat but use your brains at the hills.

Dude dont use your cruise control in 60 KM area and or around sharp bends and hills and you will never have that problem. Keep it to the even level freeway where smooth, high speed, long distance driving is needed..

If you have the cruise set at 110kmph on the freeway its illegal to speed up fo the hill so you are still doing your 110 in your underpowered falcon or commodore at the top!!!

Dunno what truck your driving but mine tells me when something goes wrong......We are out of the Stoneage now.

If you were to drive a car without cuise and hit the same hill that the cruise control supplied full throttle for you too would have to plant your foot all the way up... but thats after you realized you were doing 90k's.

After a few yrs in a Aeromax with no cruise and 18speed RRanger then driving my new Sterling with 18speed auto and Cruise I feel much better after a days/nights driving.

Anything that can make my job easier is a bonus.... means Im more alert because I am not a fatigued.....IN MY OPINION!!!!!!!!!!!!!!!!!

I think cruise control is great when a lot of highway driving (i.e. interstate), but if you're just driving to work on the local freeway, it's probably not so safe. People pop out from seemingly nowhere, change 4 lanes at a time, talk on their mobile and break suddenly.

Also, it's not efficient on the windy or undulating roads. The first one's obvious (lots of speed changes required), the second one is that I find the cruise control system is reactive rather than proactive. A human will see a hill ahead and instinctively step on the gas a bit before the hill and likewise, ease off when nearing the top. The cruise control can't predict this, so it tends to struggle up the hill and overshoot at the top. This is assuming that generally you're in top gear (5th or 6th) on the highway, and has the least power/torque in this gear.

It's a great "nice to have" for those long trips to NSW or whatever -- who says that sports / hi performance cars can't drive long distances? It allows you to relax a bit and not have to worry about the speed as much. But still no substitute for being alert and concentrating.

i had it on my old vx commodore. hills don't suddenly go from flat to hill. there is usually a transition period. if you pay attention to the accelerator (rest your foot on it) you will see that as the hill gets steeper the accelerator goes down further. it doesn't just stay where it was then go "oh shit" and floor it straight away. it does the same thing you would if you were staying the same speed without breaking the speed limit.

how do they control the speed? i.e. what are they connected to?

most work off the ecu's speed sensor, the tps and they have a second throttle cable hooked up to the throttle body that goes into a little motor to pull on the cable to apply or let off the throttle.

I thought that's exactly what I just said.

Nobody drives at 60 with cruise on CCCP. Well maybe my dad but he loves his cruise.

Mad 082 I know how cruise control works and how you can alter your ramp rates etc.etc But if you don't have sufficient power to start with, as in your VX, you'll find at the top of the hill the acelerator will be right down. Check your torque curve on the VX. At cruising speed, it will be doing around 1800-2000rpm. Probably making about 50rwkw. Only takes the aircon to cut in and you've lost 5KW. Whereas if you'd dropped back a gear at the start, you'd be in peak torque range and the car would eat the hill.

As for the modern trucky Turbo Dave, keep at it. You've got a lot of miles to catch up.

I think cruise control should be banned on cars i think it causes crashes

You should write articles for the police force.

As for using less fuel, I found it the opposite in both my commodore, and my dads commodore, was adding around 1 - 2L of fuel required per 100km.

As for not getting done. Ever looked down whilst coming down a hill? I found my car, and also my fathers, loved to just hold the throttle open coming down a hill till your doing around 10-15km/h over the limit, then it'd close the throttle SOME, but not all the way.

My uncle also got done for speeding on Cruise. Car set at 100km/h, copper pulled him at 112km/h going UP a hill (Car decided it had slowed a bit, needed more power, so it changed down a gear *auto* and accelerated, to above the limit)

I've had it in my old car, and I did use it, but I had to be ever so vigilant, now that the skyline doesn't have it, I get in a car with CC and don't even use it.

Also, you shouldn't use cruise in the wet either.

I'm a big fan of Cruise. I use cruise everywhere, including on 50kph streets. I hate getting fines (not that I've had one in the last 5 years) and so use the CC as a speed control device. Accelerate to speed limit, activate cruise.

It's easy, it's what it's there for and it works. My wife's VW GTI had an instantaneous litres/100k readout and on a flat surface the thing is rock solid. Undulating, I've never seen the cruise be more than a few kph behind set speed going up a hill, and I've NEVER seen it over the limit anywhere other than a a very steep hill, and at a very steep hill, even if you don't have cruise, you are going to accelerate.

I think the argument about things jumping out at you on suburban roads is a little misguided. In these days of constant speed watching, it could be said that cruise is a safety device. The less time I spent looking down at my speedo, the more time I'm looking at the road ready for those things that "Jump out at me"

I hate not having CC in my R34, especially on the trip to Deca when you want to relax and constantly be speed checking. I have done a LOT of kilometers for work in cars both with and without cruise. I'm much more alert and less tired after a few hours on cruise than not. This makes me a safer driver on cruise.

I had cruise control fitted to my stagea. I am cruise control freak. (most people think just control freak!). I luv it. Not only for trips but also around town. I even use it sometimes in the school zones (40kph). You just never know when Mr Plod is going to be pointing a radar gun at you. Oh I turn it off for drag racing though!

Oh yeah $640 at Cruisewest. Nice unit, on the wheel, Looks like Nissan fitted it.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
