I understand the engines are the same. I 've read here that the programming is probably different due to extra wt in the j and to give a different ride as a tourer. a friend who is heavy into the z32 can burn a copy of an aftermarket chip for the na vg30. was wondering if there would be any problems in installing it in my j. would appreciate any first hand insight from those who have tried. thanks.
also, has anybody powder coated the t model 15" BBS rims? thinking about doing mine.

your J30 has a 16 bit ECU.
which means him burning anything will not help you, because you can only socket and " burn" chips for 8 Bit ECUs.
You can, however, simply use a 16 or 8 bit 300ZX unit.
I can also assure you that the maps are identical, however.
differences do exist for the automatic versions in the transmission controller.
So, in conclusion, the only reason to switch to a 300ZX ECU is if you want to be able to socket it and get an upgraded EPROM i.e. JWT etc.
Keep in mind if you decide to swap that you will need an ECU from an automatic 300zx, and take note if the car is federal or california. there are differences.
In fact, the twin turbo maps are identical to the NA maps, although the ECU will show an error code due to the lack of boost solenoids etc.

onefast, i would be interested in knowing what adjustments were made as well. thanks for the info everyone, looks like i'll be looking for a na auto z32 ecu. suggestions on where to get one?
cweber, i was thinking of a bronze color, or maybe the champaign sp? color on the new rims. my j is the maroonish brown.
