ecu in automatics
 

what ecu's are compatible with automatic rx-7's. What kind of power can be made with the stock turbos and is it safe to use a piggy back if you switch to a single setup?

Try searching and next time use the ECU section.

the apexi power fc will work w/ a auto tranny, but i think you will loose your hold function.
also with an auto tranny, you cant get much more than 300hp out of them, because the tranny cant handle it.

I'm running a Peter Farrel Purplebox. I think this is one of your better options as it is a piggy back, thus allowing you to keep all tranny functions.
