Advice on Automotive Data Logger Project

Hi all,

I am interested in building a data logger for my race car. I hope to run 1-2 hall effect sensors and an accelerometer, as well as potentially several weather inputs (temp, pressure) and gps (if possible) for speed. I would like to log using an SD shield and also add a small LCD screen to toggle through various readings.

I am a total beginner, however I am eager to learn. I would like your advice on hardware selection and feasibility of the project. If anyone can suggest sensors that will be suitable for a racing environment I would appreciate it. I also plan on using an uno. Will this be suitable? Should I be worried about RFI/EMI? Anything else to consider at this time? Open to all suggestions, thank you.

If it was me, I would do this in two parts.
I would use a controller to do data gathering then use Jack Christensen's serial data logger to store the data.

What would be your reasoning for the two part approach? Would this still be within the scope of a beginner?

Jack's serial data logger is self contained and the software is proven.
If you make a new project that needs data logging, all you have to do is plug the serial logger into it.

With the data logger software on a separate ATMEGA386 gives all the memory on your acquisition controller to be used for that job.
