Because your going to turbo your car, get e-manage.
If you've decided not to turbo, go with power FC
That's the thing...I'm not going to turbo it for a while now, at least 6 months. So should I try Power FC? Is it reliable? I have a 2003 Celica GT automatic.
Thanks for the help guys
The PowerFC, because it is a full ECU replacement, will not work with an automatic, because it doesn't contain the routines for shifting through your gears. The Greddy Emanage will work, however, because it is an add-on to your current ECU.
I've heard a rumor that someone developed a PowerFC for automatics, but no one I know of has bought it yet...just go with the Emanage.
EDIT: the Emanage does work with DBW, for the same reason it works with automatics.
