Well I bought a Predator through the fasthemis.com deal, had to wait a (painful) extra week for the usb cable and driver so I could update it but I finally installed it yesterday and am running the 91 oct tune (no 93 available in my area). I must say I'm impressed, this tuner really wakes up this truck, I went out and hot rodded a little last night and am pleased with the results, I can't wait to pull my travel trailer and see what kinds of towing gains I'm warranted... But I Digress

My question is about the Data Logging, what exactly is this? What does it do? Anyone have any experience with this?

 

No personal experience here (yet), but from what I've read on the other threads I believe that option will allow you to run 1/4 mile tests, 0-60, etc and capture that data for you. IE, no need to head to the race track every time you want to run a standing Quarter Mile and brag to your Ford buddies. :-)

 

You can do stuff like this which is pretty nice. BTW, this isn't mine but just something I saw another guy had posted on a different forum that I thought looked cool.
