I have a sct xcal 2 and I've been running the Spartan archives hybrid race. I recently noticed strange shifting into 4th gear and also slow takeoffs from a stop (not always only once a couple weeks or so). Here’s my problem, I think the tunes are causing the tranny to act up so I decided to load tunes that I bought from ford performance specialties in atl. However, when i try using live load it doesn’t recognize the files (.cef) does anyone know how to load these files onto my tuner? Or how I cant convert them so live load will recognize them?
