OK, they're ready. This is a total engine management system, you can read about it here. It can be used on 1990-1996 Z32's (yes, even for the 96's). If you're local I have a shop that will install and tune them. It is a complete plug in ECU upgrade, fully tuneable via laptop or remote tuning module. It comes with a rough program that should be tuned for optimum performance once you get it. Here's a breakdown of some prices:
Replacement ECU - $1200 Remote Tuning Module - $295 Serial Link - $80
I was planning on my Z be the guinea pig for it but I won't have mine back for about another month. If you have any questions post them here or e-mail me.
