So just out of curiosity how many guys are running a OBD II app on their phone for gauges, VCDS, ect.. I have a Kiwi PLX adapter from my last audi and I seen that ross-tech has a VCDS app for iPhone, but all in all is what is the best app to use to run live gauges on my iPhone? I would like to see real time engine parameters maybe even possibly do 1/4mile times and read codes. TIA
