cruise control

[ragingfool35]

aftermarket kits are available for vehicles equiped with the GM VSS

going thru the EMH and MK sections I cant find any outputs suitable from the ECU

maybe I'll buy a Haynes manual for pontiac grand am quad4 and track it down in the

electrical schematics

unless...

someone has already done it?

I installed one on mine but of course the S4s is easier to hook up as we have the electronic speedo. There should be a VSS out from the ECU that you can tap into. I have a friend who just installed one on a S4 with the mechanical speedo. I'll email you some info.

On the OS rear hub there is a wheel speed sensor on my SE.

How about posting it here, others are probably interested. Hint, hint!

What brand/model did you get? Does it work well? Any issues? Thanks!

Hey Sanj,

I did a write-up on it at the time and actually submitted it to LEW but I guess it didn't make the grade.

The unit was made by Rostra and purchased from Dakota Digital. It's been installed for 3 years and works great, never a problem once I got the settings and calibration correct.

If anyone is interested in the install write-up, pm or email me your email and I'll send you the word .doc.

Here's a couple of pics:

The control module under the bonnet

The control stalk

Jim

I greatly appreciate the info

It looks like Rostra is the only (or maybe just most popular) aftermarket cruise control out there

your buddy pointed me to the place he purchased his from ( www.brandondist.com ) stating they

had the best prices. a quick search showed him to be correct

ordered mine today for $217 with shipping. got the pannel mount control instead of stalk and will find some cool place to install it.

he also installed to gas pedal and also used the 8000 pulse per mile with low gain, taking signal from ECU red harness (J2) pin B8

very helpfull fellow (I hope he does not mind me posting his efforts)

maybe Sanj would be good enough to mark up the electrical schematics and we can add to your write up

maybe even make the LEW grade

Thanks for the info. I take it you used the non-vacuum version?

not to go tooooo far off-topic here...

I noticed the cover over your bonnet electronics - where the relays, CDL, radio interference, ...are. My cover is much smaller (on the firewall behind the control unit).

Is that a factory cover - hiding more electronics in the S4?

I would like to buy one - and use it to cover up the additional components I added last weekend when I added an alarm system.

Lou,

Yes it's OEM.

I think a cruise control would be a great addition to improve the comfort on a long trip. It is hard to keep your foot jammed in one position for great lengths of time. It seems to hurt my hip and knee joints as well. It is also very hard to hold constant speed w/ the power capability of our cars. One small movement & your waaay over the speed limit!

Jim,

I would be interested to see it posted here as well since my car is carbed, but I may also want to add an electric speedo.

Thanks, Lee

Hey Jim, did you have to add a clutch switch? If so, was it included in the kit?

Great work dude, thank you

The clutch kit is an option and not included and I did not use it. The engine will over rev if you push the clutch in while the CC is activated but I have not found that to be a problem as I tap the brake pedal before pushing in the clutch which deactivates the unit.

I originally thought the tach wire was supposed to control the over rev but I guess that only applies to an automatic transmission application. In thinking about it, I may change the dip switch setting from manual transmission to automatic and see if that makes any difference...

If you want one I would try and get one second hand. I wanted a new Plenum cover ( the bit the boot gas strut attaches to) as mine had broken. Its only thin ABS as is the relay cover, but the OEM part was almost

Great work dude, thank you

Rock on! Been wondering about this for some time! I'll order one up soon!
