hi can some one give me some info on this ecu Z5 i have just looked under the kick plate to see what ecu i have in my 1994 wrx import want to no if they a mapperble and what diffrace there is in a stanard wrx ecu to the z5 ecu hope you can help thanks

 

Z5 is like a Z4 with rev limit at 8000rpm afaik. Which means 260ps. Standard ECU for some wrx RA's I think. Its safe to run in your wrx but dont rev it beyond 7k rpm. They are not mappable but you can insert mapped chips into them like scoobyecu's and esl chips. Do a search and all will be revealed with regards to these chips. You can get a custom map on them but many places charge a fortune for this.

 

as far as i know they are not mappable they should increase boost and give it a more aggresive fuel2air ratio plus addind about 20.to 30 bhp i think
