Recently I installed a 95 wrx Z4 ecu(reads z4 on the sticker) in my 93 wrx ra. The RA has a stock 60 000km ej20g other than an apexi induction kit (im making a heat shield asap dont worry :) )...and JIC mandrel bent 3" catback exhaust.
When it had the stock u8 ecu it was good too however maybe I was too optimistic with the z4 ecu as it really doesn't feel like much of a difference.
I read that its a safer tune atleast so thats very good to know I was just wondering if there is perhaps a lower output automatic Z4 ecu which I may of gotten if one exists. However I hope there is just one "z4" ecu out of the 260bhp wrx's. Currently boosts a bit over 0.75 bar on 94 octane(98 ron equivalent). I teed boost hose into the far right port of the 3 on the top of the intake manifold closer to the front of the engine.
