wondering if anyone here has a lap timer program for their windows mobile device with a gps built in?

what one do you guys use?

 

maxqdata

 

I know the guy who does the ontrack testing and debugging for maxqdata, by the way.

 

I've seen and tried the free-ware version of the MaxQ software, and I know patinum uses it and likes it.

however keep in mind that the built-in GPS of your Windows Mobile device is very unlikely (I think impossible due to the GPS chipset it uses) to have a sufficient enough refresh rate to be useful.

A very few GPS receivers have a refresh rate faster than 1 Hz. The problem here is that even at only 60 mph, you have an 88 foot margin of error with each 'tick' of the program. The software will interpolate the data, but this makes it useless for precise info for it's two prime uses:

1. Laptimes and sector times.
2. Track position (accurately drawing your line).

This is why the 1 Hz version is a free trial. Because it is not truly useful, just a way to try it out.

To make it useful you really need to get one of their tested and endorsed GPS receiver. I have done such, and bought the 'lite' unlock code, but now the problem I have is that my Windows Mobile device (WM phone) appears to be processor limited and cannot handle the flood of info.

 

alot of us spec miata guys use trackmate i used to have maxqdata but traqmate are much better for road racing

 

Yeah, well there are no free lunches. There is a reason why dedicated GPS datalogger systems tend to cost about $1000, even without video capability.

The full up maxqdata system (with the Acer notebook, the webcams, the bluetooth GPS receiver) works pretty darn well. But your typical PDA just doesn't have the speed to keep up.

 

My PDA works fine (Dell Axim X51v). It was top of the line back in the day. Battery life blows though so I keep it plugged in (and keep the processor speed to best performance).

 

sorry to sound cheap but i am looking for some free software hopefully that can just tell me a rough lap time. if i cant find it ill be using a stopwatch program.

its just for fun for me right now.

i did find a program called racechrono and ILAP.

thanks for the info on the gps reciever. i guess it prolly wont be very accurate either anyways.

 

i use Harry's Lap Timer, but it's only for Palm OS and iPhone.
it's not too expensive either.

Maybe try the free version of maxqdata (limited to 1hz). I don't see why it wouldn't work with your internal gps...
