am i correct in thinking that i can just buy a z4 ecu, install it and see power gains? i have an auto 95 wrx. i dont have a de-cat system or anything, just a different back box and better panel filter. how do these plug and play ecu's work??

A 1995 WRX should have a Z4 Ecu as standard (unless it is a wagon of course). If it is a wagon then you will need a td05 turbo as well.

The ecu's just un-plug / plug in, with the car battery disconected - 5 minute job.

mista majestic i am in the totally same boat as you...... ive been told because its an auto that theres also an ecu for the auto box wich works in conjuction with the engines ecu for engine speed and road wheel speed etc

it just seems too much work to get that power,,but i am looking into easier options of power gains using td04 turbo and standard ecu

i think the autos have a td04, not a td05. the z4 is made for a td05. also, as above i dont think a manual ecu will work in a auto car
