Hi all,

Couple of questions for you very helpful people!

Am in the process of installing a new engine in my S1. Have got hold of a rebuilt 90-spec motor. The problem I have is it came without the turbo and ECU.

Have now purchased a turbo but still have a couple issues with the ECU.

1) Will the ECU of the S1 engine run on it. I have heard stories about knock sensors being needed?

2) The black fuel ECU that was on the engine before had been "modifed" to help fueling under load. Is this an essential mod or a waste of time?

Thanks for your help
