Pro Flo 4 Tablet

I think its brilliant. Keeps the tuner at bay in the car (in your lap) while your setting up parameters, not tethered to a PC or laptop with an umbilical cord (ala Paul's Evo in 'Fast and Furious' 1!) . And its a universal platform, no proprietary junk that can break and not be replaced. Just make sure your tablet has the required resolution! The majority of the uber cheap used ones are 800x480. Most modern ones are good enough. The Google play is just a vetted platform that prevents you from downloading a malicious app that can brick your tablet or install badware. Apple has it too but demands money for the app to be in its library. Im sure the app is free.
