I had my car RR'd today cos after 4500rpm the power would just fade away to nothing almost like i'd lifted off the pedal and i couldnt figure out why.
Amongst a few other things I was told that the transducer in the ingnition ECU (silver one) has gone and as a result the timing is about 10 degrees out when it reaches 4500rpm and so i need a new ECU.

What i need to know is:

Is the transducer the component in the ecu that the vacuum pipe goes onto?

and,

If so, can i get one from anywhere?

Otherwise I will have to get another standard ECU and fit my Ahmed Bayjoo chip into it, which looks fiddly!
