GPS Speedometer for laptop?

[CamaroDude85]

If you have a so called "Smart Phone" you should be able to get a free GPS/Speedo setup on it. I have an Iphone and have "GPS Drive" on it. It works great. I am a cheapskate, so it was either free or VERY cheap.

Yep that's what I do. I use one called GPS Speedo, really simple, free and even has a HUD that'll display on the windshield. The HUD only works at night cause the screen isn't bright enough though.

There's some neat car related apps out there, got some that'll log lap times, read OBD2 codes/data and g meters.

Thank You.
I have never tuned an OBD1 or earlier system. I am hoping for some OBD2 activity here. There seems to be a lot of very sharp people here.

Tuning is tuning so what you know goes backwards or forwards and there's always more to learn. Software is all differant. We just started to add the OBDII stuff. I'm about to do the 0411 swap to my Vortec truck (thank you for the effort you share with that conversion! ) Mine will have a slight twist as I'm using a Moates RoadRunner. With it I will be able to tune with RR/TunerCat OBDII, EFI Live and I think the new frontire will be using the files for TunerPro RT! TunerPro already works with the RoadRunner!

There's a really cool app for an iPhone using the Innovate OT-2 wireless, can even wire in a LC-1 WB and it's wireless to the phone and wireless to laptop. I have the OT-2 but it sucks with just LogWorks, only one channel, no PIDS?. It was supposed to work with ScanXL Pro but there is a glitch somewhere on Innovates side? Data log in iPhone and eMail it to youself... I just don't need an expensive phone! For what they cost I could buy another laptop? Still end up needing a laptop so it's a cool toy, sometimes just because technoligy can doesn't mean you should...

Stopwatch.

Pass mile marker = "go." At one full mile = "stop." 3600 / recorded time = speed in MPH. Also quick and easy method to check if speedo is close. Set at 60 and drive through mile with stopwatch. There's a 10 second window on either side. If you travel a mile in 50 secs that's 70 mph. If you cross a mile in 70 seconds you're only doing 50. Most phones come with a stopwatch.

Yeah but that's Old Skool for carbs and points! Won't work with EFI...

Well I'll be, my phone has a stop watch. But can't run and app...

So you can get the time but there's no way to get the math done?? If the windows are foggy you can do it by hand on the passenger glass!

I was just being funny... got a big kick out of the old school way, it's amazing the simple things we forget (stop watch, time and mile markers vs computers and GPS)

How accurate is MPH on GPS? I'm really splitting hairs at this point and don't think ther's an issue, just want a procedure like GPS MPH to verify tire. wheel and gear changes done to bins through software. So far I'm down to 1%. But looking at MPH on laptop to verify would be simple compared to times, miles and math. No biggy...

Me too. The idea of doing long division on the fog inside your window just to figure out the speedo seems funny, especially after using technology (the phone) to get the time in the first place. It's the visual that makes me laugh the most.

Non- military GPS data is accurate to within 25.59 feet at best. But there are multiple satellite and ground based augmentation systems which can be used to narrow position even further down to millimeters in some cases. DOT, FAA, and NASA all have some type of GPS system or supplement which may be used by a GPS unit to determine location. So ultimately the accuracy will depend on what's available where you are for supplemental data and what your gps unit uses if anything to narrow your location. If you can get within 26 feet of your actual location and you're crossing distances over 5,000 feet your speed information will be more accurate than most speedometers.
