I am looking for a program for my N95 to measure top speed and acceleration 0-100km/h and more in my car.
It have to work whit external bluetooth GPS modul.

GPS probably isn't your best bet for using as an accelerometer, if your car is less than 5-6 years old then chances are it has an OBD port on it. You can use this to connect a computer and get data from the car's elecetronics.

There's plenty of software that will record top speed, acceleration and revs etc

Elmscan is a good starting point.

But GPS isn't good for measuring acceleration, it's accuracy for measuring speed is also effected by other things such as altitude.

I've had a quick search and I can't find anything for SymbianOS that will do what you want I'm afraid, there's stuff for laptops but the same as the OBD solution you would need a laptop in the car whilst you're collecting the data.

Here you are h**p://www.tempes.com/ Excellent produce unfortunatly he wont be updating it to use internal GPS as I emailed him. But for what it is its great! 0-60 times and 1/4 mile times

I'd be surprised if using GPS would be accurate. GPS messages are sent approximately once per seconds, which is nowhere near accurate to measure 0-60 times. Also the accuracy of GPS is also pretty lame, the speeds it reports is only accurate over a large distance on flat terrain.

Interesting question.
By the way, how accurate is the speed measuring of the GPS?
I have seen while I'm driving with GPS, that the GPS meassured speed is always slower then the speed on my cars speed indicator.

When I'm driving 120 km/h the GPS tells me my actual speed is 112 km/h.
When driving 90 km/h the GPS speed is at 84 km/h.

So I'm wondering, how accurate is the actual speed measuring shown on the GPS?
I'm using the external GPS receiver from Nokia.

GPS should be more accurate than your car speedo, unless it's been calibrated (like some police cars).

Sounds like your car is 7% out, which is within the normal tolerance. (For comparison, my car's 10% out and my bike is pretty much dead on.)
