I've looked at their maps, no doubt. I've also found issues with them such as the lack of properly scaled maps for running boost higher than ~14psi. Their maps simply dont go higher than that.
As far as copying and selling them, I have done nothing of the sort. I had two genuine NA JWT ECU's that I paid for and sold a while back, but I State again, they are genuine JWT ECU's. I have not copied and sold their program to anyone. I think something that Nixit misunderstood a long while back got blown all out of proportion (and I have spoken with him about it) and he skewed what I was saying into me copying and selling their chips. I haven't done anything of the like. I've just looked at *some* of the remappings the have done to see how well they do it. Unfortunately, they got probs. :)
