Ok guys, now I know most of you are going to come in here and say its imposible to run the motor on stock ecu, but mostly that would be assumption. The auto tranny is going to the trash first off, but can I run a stock 20b on a stock 20b ecu in the fd3s? I have a stand alone that will be coming but it may be a bit of a wait before its availible to me, so whats required to run on stock ecu, at stock boost.

 

let me get that auto bell housing!
and i see no reason the stock ecu could run the engine in stock form(stock turbos at stock boost)
as for the EMS taking time to get there???? wait for it, dont rush on driving the car. Im sure you did everything else with care and concern, wait it out and do it right or the way you plan to.
