I'm using an emerald one http://www.emeraldm3d.co.uk really good ECU, and its lots more developed now, the site is out of date by a lot! Don't know MSNS but any ECU will work, the biggest problem is the Nissan CAS trigger pattern. You either have to get an ECU that works with it, modify the trigger disk in it or fit an alternative pickup. Don't forget to see how the software for the ECU is, some aftermarket ones have awful mapping software that is awful to use. Emerald is great.
Should have some info on VH-->Z32 tranny info soon too.
