Hey guys,
I understand you can unlock the PFC if you have the FC-Logit Software. I have it for the R32 GTR (and I think it does R33 GTR as well).
Anyway, if anyone does have a locked PFC and wants I'm happy to let you use my gear to unlock it.
I'm with you guys, you pay for a tune and you own it unless you have signed some sort of licensing agreement. Warranty is an interesting point, although
I think a better solution would be for a workshop to say "If you want full warranty then we lock the ECU". If you want it unlocked its $50 (or whatever a reasonable cost is for the 10 minutes it takes to do) but your warranty is over.
