I have a 90' ef wit a y7 but will be swapping a y8 in soon..and im using my stock a6 ecu(need to instructions for the a6 ecu and y7)

What are you trying to say?

You are preparing for the D16Y8 to go in with a different OBD?

What is the reason you need to do this conversion? You do not need to do that if you ar going to be running the D16A6 ECU as they only need an 1-Wire O2 sensor.

 

well pretty much aiming for better mileage..i was told the 4-wire o2 give better gas mileage..

 

A PM6 (d16a6 ecu) wouldn't even know what to do with a 4 wire o2 sensor. 4 wire o2 sensors are for obd1 and up. Just get a new 1 wire o2 sensor.
