The cost of a remap on the Patrol would be broken down in the following way:
1. Labour to remove ECU, open it, cross the pins to allow it to be remapped, remap and tinker, close it and reinstall in the Patrol.
2. Tuner to pay off the licensing fee and maps/hardware purchased to remap (have heard around $20000 but not sure)
3. Fat profit!!!
The fat profit on it's own might not be too bad and would be what most people would think an ECU remap is worth but there are the other aspects.
If a car can be directly remapped via the port then it should be cheaper and also include real time tuning on a dyno. If more people are doing it then it will get cheaper but there is a limit as if you use the maps and software from a reputable company that has researched what it does they will want their costs recouped. For instance, I asked the tuner if he could switch off the EGR or at least the P0401 error but he said that the software would not allow it as they pay a licence fee to Nissan to get the base code and part of the deal is not to tinker with certain things. He also said that the software wont allow him to exceed certain parameters that are considered unsafe by Nissan.
I don't know if someone could crack the code and tinker on their own but would you really trust someone doing that? Most places are getting their maps and software from Europe which has been doing this for a while so there has been some research/experience into remapping diesels even if it is new over here.
