Hello Cuts,
I also have a Mark X, but I am still in Japan and want to bring it back. (under 1 year ownership so I can’t do personal import)
As far for the ECU there’s not much that can be done with stock ECU, as it is from Denso and locked, piggy back is the only way, but that has it limits also. As for rear diff, not to sure, I would have to check out the part numbers at work. Since its a new car the options are limited at the moment.
Also to note, you only can turn off the Traction control, but the stability will always remain on.
When I asked aound it was going to cost heaps just to get the compliance done on it.
Just wondering which work shop this is going through? And what they estimate for the compliance?
