Sorry my friend but they are definitely not the same. I have downloaded the RX-7 one and have a copy of the one that suits the BNR32/33/34, ECR33, GCF8 and S14 and they are worlds apart in the sub-menus.
Now my thinking here is that as those all come under the same part number (RX-7 is different) and the ER34 RB25DET (NEO) has a completely different part number again, it would be fairly safe to assume that the sub-menu for the ER-34 will be different again.
So anyone out there have a copy of one for the R34. It can be in Japanese as I have two excellent translators in the household.
Some one must have one surely.
