For AFR's that mean anything you'll need a wide band, stock o2 sensors are for cruise afr's only

You will alway need a wideband controller for a wideband sensor....Unless your using an ecu with a controller built in (think Motec).

theres also another more basic app called "Dynolicious" which claims to measure things like G force, km/h, hp, 0-60 time, and can test whether new mods make a difference in these.
i just downloaded it so ill see how it goes.

Dynolicious works pretty well - logs acceleration and G-Force data with decent accuracy.
Just make sure that you have your iPhone mounted so that it doesn't move around.

Dynolicious doesn't use gps. It relies on the accelerometers in the iphone (ie it guesstimates the data).

REV2 uses GPS & Mapping for lap times etc.

Download REVlite and give it a whirl.
