quick ecu question
 

Hi all.

Ive got a 75 ecu in my v4 sti and my question is would there be any difference between this and a z4 ecu once fitted as i can possibly get a z4 with esl already fitted cheap.

Thanks andy

Now know the answer thanks

Ull have a job fitting it, 75 is a 3 plug and the z4 is 4 plug....
