  • Gps Performance Meter?

    Does anyone know of any software that is capable of capturing 0-60, 0-100 or 1/4 mile times from a GPS. Is the GPS data accurate enough??

    .....Sorry just found the other posts.

        Here is an option

        Not sure if you want to spend money or not but I use this:

        The serial interface plugs into the ODB2 sensor on the car.

        Works great

          GPS for performance measurement? Useless cuz most GPS receiver/software update like one a second or so. Maybe OBD2 but not GPS.

            Proscan v2 has Dyno & Drag strip recording facilities but will need an ELM compatible OBDII Serial Interface card to enable it to work on a CarPC or Laptop...

            Other than that seach Ebay for a G-Tech Performance Meter. They usually sell for about 45 (rrp 149). This is a standalone box that will monitor its accelerometers, and IIRC GPS position, to produce timing figures. Or it may just be the more expensive unit they make that does GPS. There is enough info here for you to find out more...

              GPS simply is not accurate enough for us to use for 0-60 times. It can refresh fast enough, it's just usually not more accurate than +/- 15 feet (on a good day.)

              Accuracy is restricted by the US Government.

                Racelogic Vbox used super accurate GPS & accelerometers to provide a cars timing figures. It is extremely accurate and is used by most motoring magazines to get performance figures. It uses military grade GPS receivers.

                It can be done - But the Vbox is about 5k IIRC

                  The government turned off the Selective Availability restriction in 2000. Accuracy now only depends on the number of satellites being tracked and the capability of the receiver. The +/- 15 feet accuracy is in latitude/longitude, not speed which the gps computes separately. The problem in using this for 0-60 timing is the update rate of the receiver.

                    WAAS installations will improve accuracy. I'd think you could get a reasonably but not absolutely, accurate estimation by doing a series of runs.

                    The problem is going to be the update rate of the GPS receiver. It's too slow to be useful.

                      why not let it take speed readings once a second, log them in a spreadsheet, and using Excel plot a graph. Then let it interpolate using the other readings... It should be quite accurate.

                      0-100mph gives a better real life representation of a cars performance though these days as gearing choices for 1st and 2nd can remove a gearchange (before 60mph). IE. My 200sx will just hit 70mph in 2nd.
