Aftermarket Cruise Control

Postby maoman » Tue Sep 02, 2014 13:12

I've been thinking of installing cruise control in my car, maybe something like this. I do lots of highway driving, and I think this might help my mileage. Anyone have any experience with this?

depends on the type of tranny you have....the gear ratios dictate your mileage.....after market cruise controls can actually hinder your tranny, especially if your car is over 7 years old..cruise control is designed through torque readings out of your tranny.....IMHO, it won't change much on an older model, the engine/tranny has lost most of it's original performance-like a 60 year old running a marathon.....a 4 cylinder engine will make pretty much zero difference, if it is a 6er, then the tranny will be a little bit more responsive but not enough to justify the cost... .... might want to rethink that and just change vehicles with a six cylinder....an average four cylinder rpm on the highway at 110-120 km/hour will be around 2500-2700....conversely with a six it will hover around 2000-2200, but on two more cylinders....do the math. I would say forget it...if you had a big V-8..that's where you would notice a savings.

In Taiwan how often and long do you actually get to use the cruise control? 5min? 10min? Before you need to turn it off?

....and distinguished nothing except a single green light, minute and far away, that might have been the end of a dock.
