Hi Sean Thanks for the reply, I forgot to say the top Bosch trace is old unit, lower trace is new unit, the idle pulse I can understand and looks to me as if I`ve got four good cylinders, what I have always found difficult is what I call the severe oscillations as the revs rise, it always looks very confused to me and logically I would think the ECU would see the trace as a very rapidly accelerating and decelerating signal, that part of the aftermarket sensor signal would look more logical to me showing a rapid but smooth rise in airspeed. Re adaptions, no I did not reset, to be quite honest I`ve just bought Vag-Com myself for this vehicle (boss was dragging his feet!) and am very new to it so thought better to leave this until I`m more conversant with Vag-Com, a little learning and all that! Again thanks for all input and I hope someone else out there is learning something as I am ! Cheers Roger.
