I see them advertised all over the place. The one I was looking at by auto meter is $250 for the gauge and another $200 for the GPS unit....that's kinda steep. Other options available? I change gears and tire sizes too frequently to have a regular speedometer read accurately.
or an old garmin or tomtom. My old garmin(3yrs) has the speed on it. You can find them for sale cheap. Its around 60 bucks to get a map updated, so many people never do it and buy a new gps. http://www.ebay.com/ctg/Garmin-nuvi..._pcatid=43&_pcategid=156955&_dmpt=GPS_Devices
I use a droid app in my car right now because my speedometer isn't hooked up. The other option would be to buy a box full of gears and swap them every time. Cheaper at least.
my i phone speedo apps are very slow to respond. a car looks better with a speedometer than a cell phone on the dash.
My Garmin is more accurate than my speedo, and it tells me where to go (sure wish I could shut that lady up sometimes). I think my speedo is about 2mph off from the GPS.
Yep, love the Garmin. I use it for most of my driving. MPH displayed appears very accurate. All three of our cars have speedometers that are off by 2-3 MPH at cruise. MPH on the Garmin is updated often enough -- probably at least every second.
also consider that mo is looking to run in the silver state classic. he will be in a class that has a top speed cap in the 140s. i believe his target speed is 124mph. if what ever gps speedo only refreshes onces a second he will have gone 176ft in that second. in two seconds he has gone over a foot ball fields length. he needs to be able to accurately monitor his speed every moment of the race to judge his entry speeds for turns and to assist in his attempt to run the target course speed for the event. he uses a timer to judge when he needs to be at what speed at what point on the course. so what ever speedo he uses has to have a really fast refresh rate. so does anybody have any experience with any of the gps speedos and what there refresh rates are?
Be wary, I promise it won't be long before these sorts of things are required and reporting your speed and location to the police at all times.
I've used my old garmin GPS and it tells the speed rather quickly. If I gun it and get up to 60 mph the gps is already saying that speed.
I'm not trying to add to your work load, but why not take a navigator with you? He can measure time and distance..............kind of like the rally guys do. Or, if you are going to go solo, but a VDO Electronic speedometer......not sure which one measures time and distance....................then hook it up to a Hall Effect sensor which will give you the advantage of choosing gears and tire sizes....................then built a pod and put it on the dash so you don't have to remodel your dash...............and when you are done, unhook it until the next time.......................................IMHO
how do these hall effect electronic speedos work? I think auto meter carries one as well. I could purchase one of those. it's pretty pricey though....
My $99 6 year old TomTomOne has been downgraded to act as my Maverick's speedometer. And nothing else. I use my cell phone for all my other map and GPS needs. With a 3.80 rear, and the steepest speedo gear I can get, it is still about 10% off.
A Hall Effect Sensor takes the place of the speedometer cable. You take your regular speedometer cable out, plug in the Hall Effect Sensor....run the wires from the Hall Effect Sensor to the VDO speedometer.........and you are done. You can adjust the VDO speedometer for gear and tire changes since it has a microprocessor. Personally, I dislike speedometer cables and OEM cars and trucks no longer use them..................ain't electronics wonderful!
