@sgosnell : I'm using a 5Mhz receiver, not the one in the N810 as I understand that one is 1 Mhz

@ handful/marcelo : I would be happy to take this offline with you, just send me your email address and if you are keen to take up this project, we could take this forward. I know you guys have done stuff like this, and if we take this forward, we can develop the logging component and basic lap timing as phase 1, then introducing the rest of the features as we go along. I will leave it to your discretion on whether you want to offer this as freeware, commercial, shareware or donationware. There is a fairly large market of amateur motorsport enthusiasts who would balk at spending over USD800 on a unit such as the RaceLogic Performance Box (and who don't need the accelerometers), and the Nokia Internet Tablet would make an excellent alternative offering lap timing, analysis (which you could offer as a Pro version), GPS navigation (good to be able to get home after track day), music and video jukebox and mobile internet device.

Integration to Carman would allow users to diagnose and reset DTCs without needing to lug around a separate device. This integration could be used to display real-time graphs and warning indicators.

I have a Tactrix cable (http://www.tactrix.com) that I use for datalogging ECU data from my track Mitsubishi Lancer Evolution VIII MR and use Mitsulogger (http://www.aktivematrix.com)

When this project is complete, you guys can look into selling hardware, software and accessory bundles, and we can test compatibility across multiple vehicle makes and I can assist in the promotion of this setup.

Let me know -- As a product and launch manager, I would like to offer you guys my years of experience in product development (from a requirements perspective) and marketing if it would help take this project forward.
