Hi guys,
Just spent the best part of the last hour reading this thread. I'm like a sponge absorbing all the great info and experience here! Thank you all for contributing and sharing.

Have any of you used or have an opinion on the AEM V2 Plug and play ECU? AEM Series 2 EMS - Plug and Play Engine Management - Wideband O2 UEGO, Water/Methanol, Stand Alone Engine Management, Piggyback F/IC, Tru Boost Controller, Gauges, Automotive Performance Electronics

This is one of the only ECU's I have found, That from what I've been told will fully control the automatic transmission in my MX83 Cressida, with JZX90 1jz and auto transmission. The other option I have is to use something like a "suprastick" to control the trans. But I am unsure wether they provide full control....ie, select "D" and drive as normal.
