Hi I'm not really swaping, there was no engine in the car when I buy it and the S5 TII engine/ECU was with.. as an unfinished project.

The fact is that I'm swaping the motor and I'm not really sure wich ECU to use with.

Here a listing of what I got:

-TII engine
-TII ECU + harness
-N/A S4 ECU + Cluster and his harness
-TII Tranny

So can I use the N/A ECU with the S5 TII Motor ? I probably think that I can't beacause of the turbo but..

An other question, wich modification I have to make on the cluster harness to fit the S5 TII ECU ?

Thanks !
