JWT ECU question

A friend has a 98 Altima SE and we want to do an FMAX Stage 1 kit on it. FMAX says their kit will only work with the 97 and older Altimas, because of the JWT ECU. In other words it's the same problem SE-R owners have - JWT hasn't cracked the 98+ ECUs, and you can't just bolt a 97 ECU into a 98, it won't work.

So my question is, does anybody have any information on getting an older Altima ECU to work in a 98? On the SE-R side it requires a little rewiring, nothing too major - if anybody has any information on specifically what needs to be done to get an older JWT ECU to work in a 98 Altima, I'd really appreciate it. We don't want to go standalone with the engine management if we can avoid it at all.

my buddy is running an earlier ecu on his 97.5(obdII) turbonetics kit and hes having problems with it now. jwt is not the best place there is for the turbo setup but unfortunately, its probably the only place for an altima at the moment. there are various pin-out diagrams on the net that are available and if memory serves me correctly, i have one of them on my computer at home. when i get home later, ill see if i can find that and post it. until then, youre more or less stuck with changing the wires over to run the earlier ecu's that have been reprogrammed by jwt.
