Aem Standalone

[Scubaru Steve]

so some of you may know we tried to boost the echo and the e-manage and aem fic are unable to compete with toyota's automatic lack of going into open loop.

So i am looking into the aem ems-4 to power this beast. biggest reason is, it is a full stand alone. no fooling required just tuning. i also have an account with a tuning shop so i can get some items at wholesale.

anyone have any experience? i loved the tuning program of the fic, just the computer un-learned all my tuning.

I use the EMS (3 years old now), not sure what differences there might be with the 4.

I have no issues tuning the FIC and 550cc injectors. The stock Ecu hasn't tried to mess with my tune.
