The log file can be analyzed using the PerformanceTools software suite on the PC, which prompted me to wonder if a similar application concept could be executed by the Internet Tablet.
Forget GPS and use WII remote. There is already many projects + maemo garage projects Py Axel Wii (http://pyaxelwii.garage.maemo.org/)
Well you could use gps for accuring and sync location coordinates when you are standing still (GPS accuracy as it best). I believe this could be great feature for maemo mapper as well. N800 users wouldn't even need gps because they could just point out start position at map layout. Thats assuming they know where they are.
As mentioned previously, this project is meant to offer a low-cost alternative to motorsport enthusiasts and not as a replacement for more accurate logging tools such as the PerformanceBox. Seeing that the cost of the N800 is going anywhere but up, with prices falling to under USD250 a unit, adding a USD99 GPS receiver and a USD75 16GB SDHC card will turn the N800 into a personal navigation device, a portable media player, a mobile internet tablet and a motorsport datalogging and analysis tool.
The challenge here today is not whether the Wii controller (which I agree is a great idea) would make a good enhancement to the setup, but if we can find a developer to help bring this idea to fruition.
My offer stands to help bring this project to light, and seeing that I lack the necessary skills for development, a partner is sought in this area to help make this concept a reality. I, for one, know that the iT has the capabilities for datalogging and analysis, as well as display of real-time information based on live data feeds from the GPS receiver as well as other sources such as an OBD-II port.

Well I have heard that WII remote accelerometer is very good, but how its performs at track is different story. It needs to bee tested.
There are ways to reduce this "position error as the square of time" dilemma at race track.
Simple way it's users sync as new lap starts users taps screen, preses button or plays a sound.
Little advance method would bee use WII IR leds, but if WII IR can't receive its more tricky.
As in map or navigation mode it should bee hard to correct your position every now and then. When we have tested results how long accelerometer error stays in reasonable rates. We can time gps or users syncs accordingly.
Does somebody actually know more about WII remote. How sensitive it is, can it be programmed in any way, Whats is power consumption in active use, Does it draw more or less power than gps receiver ?

Okay, we will need to assume that the unit will be plugged into the car charger. A Wii controller would offer the ability to measure lateral G and acceleration/deceleration.
Marcelo, do you know any developers who would be keen to take on such a project?

I'm cross-posting this over to Apps in the hope for better exposure...

How much are Wii controllers and an OBD2-Bluetooth connection? Can they both be connected at the same time?
If they are cheap enough, people might buy them and play around just for fun, otherwise cost is probably a limiting factor for most people, especially if they don't really have a goal in mind.
The other limiting factor in my case is that I don't think I have an OBD2 port. Buying a new car to rectify that little issue makes it even more expensive ;D

Ok, so I see one can get a BT OBD2 scanner for ~£100.
Not too expensive, but certainly enough to need a definite project to use it with.

It's probably proprietary (what little bus data there may be), a 1996 Renault Clio RSi.
I hope to buy something new(ish) in the next few months, then my interest in looking at OBD data will no doubt increase (vehicle driveability analysis was my PhD, this would have been useful back then

You're right, Google doesn't return any relevant results on the 1996 Clio using CAN or OBD-I/II.
Any developers keen to take up this project? This has commercial potential, and I would be happy to assist in marketing the software across various online motorsport forums
