Well, i started my ECU swap today and thought i would document it as i went along, for future reference!
Didnt get much done before the rain started, just fitted the inlet air temp sensor in the metal elbow between the AFM and the turbo.
The sensor is off an ST205 GT4 that has the sensor in the airbox lid. it was just a matter of drilling a 20mm hole in the elbow with a holesaw, then fitting the rubber retaining gromment into place and sealing it with instant gasket, then pushing the sensor into the rubber retainer.

Pics describe it better!
