07 S Adding cruise control?

[Matt Fisher]

Has anyone figured out what's needed to add cruise control to an 07 S Sentra? I'd like to use factory parts, and with the drive by wire throttle, it wouldn't surprise me if I only needed the steering wheel controls and a way to turn this option "on" in the computer. My wife likes her new car, but no cruise kinda stinks on long trips.

Thanks.

You'd need a new ECU and the controls at the least. Not exactly sure what else though. Talk to a dealer.

Bugger.I presume no one has cracked the code on the factory ECU yet?

In addition to the cruise control, I'm betting there's some performance available too. The factory calibration for the CVT seems rather off, as letting off the throttle from wide open gives you a momentary burst of acceleration.

They still haven't cracked the '00-'06 ECUs' codes. In this case though, I think you'd have to have another pin in the pinout for it to work anyway since the ECU would need a cruise control module.

It seems like a terrible idea to have letting off the throttle cause acceleration, even briefly...

[Matt Fisher]

A cruise module? Interesting. While you're probably right, it just seems that with the car already being throttle by wire, it would be purely a programming issue, not hardware.

The acceleration thing isn't a big deal, it's not like lifting the throttle suddenly turns it into a powerful car, and most people don't notice it unless I point it out. I've seen/felt this before on atv's with a poorly calibrated cvt. One would think that a mfg with millions of dollars poured into R&D would have done enough testing to have wfo = maximum acceleration.

The thing is, each ECU can have a different number or correlation of pins based on equipment. Since this car didn't come with cruise, it may not have the pinout for it. It's not a separate module.

However, it's entirely possible that it's simply a programming issue. Nissan may be able to program it to have cruise control for a fee, but I wouldn't bet on it.

I have no idea why any car would come without cruise nowadays.

It's cheaper. It does require pretty much everything you just named off previously.

Well, from an actual mfg cost standpoint, you're only talking about a few dollars to add the steering wheel controls and another pinout on the same computer chassis (assuming there's an actual physical difference). Most options are huge profit generators for mfg's, that's why they charge what they do.

From Nissan's standpoint, by bundling cruise control together with other options, it creates the illusion of higher value to the consumer.

I could do without the steering wheel mounted stereo controls and the stupid tire pressure monitoring system (yes, I know that one's another example of our out of control gvt) instead of cruise control, but that's not an option at this time.

The TPMS actually HELPED me recently...it is annoying but I like that it goes off when any of my tires are below 30psi.

I could have done without the 6 cd changer but I wanted to RF amp/speaker combo...I actually took out the changer and put in a Sony GT710 and it made a HUGE difference, plus I have full control of my iPod.

The frustrating part of the GMTPMS (Government Mandated Tire Pressure Monitoring System), is the GM part of it. I think it's great to have as an available option, it's the mandated part that ticks me off. My friend has the same system on his Suburban, and when a sensor went out the other day, no other part of the computer information system worked, the damn tire needed to be removed to replace the sensor, and the stealership initially told him that all 4 needed to be replaced at a cost of $700 parts/labor. Leave it to the govt to require a $1000 system to replace a $2.00 hand held gauge in the pursuit of protecting us from ourselves.

Not that that has much to do with my cruise control dillema. (Ok, rant off).

When I get the opportunity, I'll stop by the dealership and ask what's needed to have cruise in the "S" model.

Can't say I've ever tried to sell FOUR sensors...I've had to replace them due to leaking and failure...I had to replace one when I did my rims because the nut was cross-threaded from the factory.

You might be in for a surprise when you find out how much it would cost. I believe you'd need a new BCM because of the difference in CAN systems.
