As a confessing child I recently bought an acceleration meter – the GTech Pro oO I have already been around with various devices etc. and find this for measurement 0-100, 1/4 mile etc. this thing is already quite awesome. As a small comparison I took the best run of my 330i against a “normal” attempt of my evos (unfortunately the road conditions in the evo were worse that I did not make the 1/4 mile not full … I think would have been faster than 13,34 here times the screenshot of the whole http://img.flirtfloor.de/fotos/4123/566976B.jpg
