A co-worker has a '95 Corvette. He bought a computer program called "LT-tune" that let's him plug into his OBDII port, read real-time data from the car while it's running and make changes when it's turned off. He can adjust pretty much anything from ignition timing to the settings for the electric radiator fans. Anything out there like that for the Focus? That would really be the trick setup to have on dyno day!
