If my edge would have sold on E-bay I was going to get a TP X-cal and AF1 from another member on here. He traded in his F-150 and only lives 20min from me. Since the Edge works I am going to stick with what I have. I will feel better when the calibration is stable but it really doesnt bother me Im just happy it works

 

Well, if it's working for you everything's ok, or at least I figure as much. I intentionally didn't use the word assume.

 

Just updated the Edge with the newest firmware and calibration and they were both labled stable. I never had any problems with the unstable versions though.

 

VERIFY the HEX code on your pcm is supported by the code loaded in the Edge! A 05 truck SHOULD work ,but u never know. Mine ran fine out the box(05 F150 5.4l unit).Very satisfied. Verify that any updates you download are NOT BETA(I'm not that trusting).
