Just returned back from a trip from london in my cinq. The long drive along the motorways got me thinking, would it be possible to fit after market cruise control to my cinq??

Quick google search and i found this: http://www.rostra.com/universal-aftermarket-cruise-control-by-rostra.php

Just a thought as i was quite bored lol i do around 100 miles a day to work so i may try this out just for fun!

The advert doesnt really mention whether the car would need to be programmed in some way so the car knows when crusie control is on/off, the speed you have set it at etc

Certainly on the modern day car if it allows - to retro fit cruise control you usually have to have it plugged in and set up and you normally have maybe a colour screen or something on the dash to tell you its engaged, the speed its set at, on an older dash that isnt really digitilaised in any way like a cinqs is it possible

Would an ECU on a cinq be bale to acknowledge cruise contol?

You would also need the equipment for it to be programmed I assume an independent wouldnt have this equipment, certainly not for a fiat but does fiat themselves offer some sort of service?

Its alright physically fitting it, but a waste of time if it fits and doesnt work

Proceed with caution for me, do some proper research, it may say 'universal fitting' but i bet it wouldnt fit on a Ford Model T

My understanding in the cars i have worked on with cruise control is there is a separate control computer which takes certain inputs from the ecu to judge the throttle opening.

You wouldnt need to change anything with the ecu as all the cruise control does is act as your foot.

Taking all this into account, all a universal kit would need is a control box, actuator and inputs from the break pedal, speed, rpm. These are all possible from the centos. The kit comes with stalk controls etc

I will do some more research into it, worth a try anyway.

Personally I wouldn't bother and I certainly wouldn't fit anything mechanical to my throttle linkage or pedal.

To do it well you really need a fly by wire throtle and some kind feedback from the speed sensor and brake pedal (brake light switch should suffice, or 2 for redundancy). It could be designed fairly easily with a PIC or even Arduino especially if you just set it to maintain the speed your at and use the standard instrementation etc.

I'd rather spend time and energy on things which will make the car more enjoyable in other areas. The only time cruise control is useful is when you have itchy feet while scoffing a Mc Donalds doing 100mph.
 
Im a bit sceptical about the safety of it all although there are many failsafes.

The kit iv linked to uses a speed sensor, brake pedal sensor, clutch, rpm and a few others.

Sadly im at the age where performance mods are still too expensive for another year or two :( thus trying to spec it out with big car kit ;)

Maybe a feet itching gadget? :p

I'm sure a home fitted cruise control kit would scare your insurance company a lot more than some springz and a zorst lol.

I'd check first before you even contemplate doing it. As for any of the Polish chaps having done it, I very much doubt it. Most Polish roads except the very newest ones require your constant attention and complete control of everything possible.

Thats a good point! I will check just for fun, but i guess this idea is heading for the bin now!

Just trying to think of ideas to make the car more fun and usable before i go horse power hunting!!
 
I fit cruse control kits at work, there not hard to do but you will need a speed pulse if you don't have a speedo cable its no problem, if you do, then you'll need a speed pulse generator either one that attaches onto the cable or one that attaches onto the drive shaft.

you'll have to attach the motor box inside the engine bay, you can mount it in the car, but its a bit noisy so better in the engine bay, I'd run the cable into the car and attach it to the peddle.
I'd personally go for a laserline kit, have a look at my works website, the storks are lovely, really look factory.
(I'm not selling, but I've fitted lots of these and know there good)

Thanks for the info! Which laserline kit would be best for a cinq? Vaccum or electronic?

Where could i get a speedpulse generator from?

Chris
 
I'd go for a AP500 with CM35 stork, actually, you may need the right hand stork I'm not sure how much room you have on the couling I've not done the vacuum ones so cant comment on them, the electric ones arn't bad, I put one on a new hyundi i10, it wasn't too bad to fit, cant believe there still using a throttle cable on a new car! as for the speed pulse, not sure who we use, maybe worth giving the shop a bell and asking for some more info (better not tell them you've been talking to me on here tho)
 
The unit you show is a mechanical type you basically have another cable which connects to throttle cable this is then clamped via a solenoid. the safety switch is via the brake switch.
a very dangerous method . Switch failiure etc
 
its hardly "a very dangerous method" I've fitted loads of these things and never had a problem. next you'll be giving us the "end of the world" speech about the Y2K bug learking in fly by wire throttles and how a stray screw will have you careering into the back of a truck

can you explain these very dangerous problems with them please
