S3 to S4 ECU and Wiring. Info?

I thought there was a thread on this, but has anyone done this successfully?
I would like to use the bigger AFM and a second set of injectors with some tunability (RTEK)
Car is 85 GSL-SE. Engine is a ported S5 with Turbo housings, S4 intake, and all S3 electronics. Including injectors. I know I could get more potential out of this engine with the S4 ECU and wiring along with an RTEK.
Just would like to know if it has been done and if so HOW??
