do i have to get a jap spec ecu or can I use an aussie ecu pulled from a liberty rs for ej20g

which version of the G

is it an RS motor or a GT motor only easy way to tell is to count the number of blades on the the turbine

theroeticly yes it will work fine

mods move this to conversions

if your using a jdm ej20g engine in your impreza, you will most likely need the jdm ecu, a liberty ecu will not work with it.

thats what this guy from the liberty RS forum is telling me cause I'm trying to source one from down under...who to believe :confused:

um not so much
block+heads+injectors+manafolds++++ are the same
what is differnt is the turbo,cams(depending on the model), intercooler and spark/fuel mapping
it will definatly start and run . but may not run well
a liberty ecu + a piggy back (like an emanage woul be a plasuable solution)


do you have the harness?
unless its really cheep there are better plug n play options like a: link, autronic, power fc or f-con
which will also help if you have to deal with 91 octane

trying to source AE801 ecu from my99 from scooby net? and AE800 ECU any info on these gurus?

i am confused why would you think a 99 ecu would work with a ej20G (93-95/96)
