Anyone know if it's possible with a laptop and alot of patience to retune a unichip or move the existing tune over from my other half broken unichip to this one myself?

I asked before in another thread if there was any cheaper alternatives and I'd like to actually learn and do it myself if I could... I'm pretty handy with a computer I just need to know if it's possible

google and youtube are your best bet.

I tried, not much comes up, the unichip site said that only registered dealers can do it, but I was hoping there might be a trick to get around that that someone here might know
