After spending some time trying to get the idle to calm down, I'm now looking into upgrading my 99' fbody pcm's operating system to the 01+ version for more idle tuning options. From what I understand, the 01+ OS's have greater flexiblity in the idle tuning. And yes, I've read the tut on idle tuning and applied what I could to my 99 version.
I have a couple of questions because I purchased this EFILive from a friend of mine, so I'm still unsure of it's capabilities. I've searched for most of these questions with no definitive answers so please forgive my ignorance. I have EFILive/Flashscan V2 version V7.5.5 (build 81).
1. Is the software/hardware I currently have capable of doing a full reflash? I read on here that only the commercial versions are capable of doing a full reflash, but I don't see any upgrades to the V2 on EFILive website from "personal" to "commercial". I see the upgrade for the V1, but not for the V2.
2. If yes to the above question, can I just reflash my 99' pcm with a newer 01+ .tun file? I'm a little unclear of the difference between a calibration flash and a full reflash. Would doing this cost me another VIN license?
3. Would it be possible or easier to just find a 01+ pcm and add another VIN License?
Any help is greatly appreciated.
