I am sorry to get into this kind of late..I recently purchased a skyline over here in the u.s. (GT-R33). My question, is the wolf system a plug and play? Meaning, does it plug up to the stock wiring harness? Does it control air conditioner, lights, etc...? Because all the Wolf system that I see here in the states (not that many), they are basically stand alone with their own wiring harnesses that you have to wire up to their own sensors. Most of the sensors they use like many other Australian stand alone units are GM sensors...So most likely you have to tap your own, etc....
I know the PFC makes a specific model application, so that helps in tuning and basically able to retain many stock functions...
As for Wolf, Motec, Autronic, Haltech..(here in the u.s.) they are true stand alone for basically a full time race car. They have more capabilities, more fuctions..but they lack the different model specific applications.
Please enlighten me with the technologies that are not available here in the u.s...I have used Haltech (sucks by the way) and presently have motec in my Honda..Which is strictly a race car.
As for the Skyline (my street car), I presently have the PFC and want to upgrade to the MAP..But since I see this discussion about other system available, I want to be school in this before I make my next purchase.
