Hello

Out of interest I downloaded an android app on my phone called GPS Acceleration.

Did a 0-60 run and it gave me 4.5 seconds.

Car is F30 330d with MPPK
S Drive
Running Shell V Power Diesel
MPS4S tyres
Temp was 0c and dry

I find this time very optimistic but could the colder air help to achieve this ?

No.

Most android phones have a GPS refresh rate of 1hz (One refresh per second).
Unless you was going down a big hill that time is utter junk unfortunately.

Plug it in via the odb port and you should get a much better refresh rate which in turn will lead to more accurate readings

Something like this can handle "up to 10hz" but realistically you'd get 7-8hz which is still almost 1/10th of a second accuracy.

try the m laptimerapp linked to the car...

Thanks for the response guys.

Did not think so... thought the cold weather might give a freak result.

The m lap timer appears to be for IOS only.

For a fiver you could get a bluetooth ODBII adapter meaning you could then use an app like Torque to give you more realistic results.

I need to nab my adapter back from a neighbour to test mine out. I believe the refresh rate is adequate.

Yes, that and the Torque app you should be able to get the 0-60 time and 1/4 mile time working without issue.

The Torque app is quite cheap for the pro version. I can't remember what you can add on the free one but I had mine set with 0-30, 0-60, 1/8, 1/4, 1/2 times and other bits and bobs.

It's all coming from the ODB port so it's getting data as accurate as your ODO would be. Sure, under or over inflating your tyres will have an impact but I'd trust this data far more than your phones GPS for the acceleration logging stuff.
