Interesting Heinz, I thought it was only the 3.7l that suffered this.
Even some 4 cyl cars suffer eg, the 4/4 with the 1800cc (silvertop & some blacktop's)
Jon, you're absolutely right I think. That's what I meant by my previous post.
Back then I don't think I had put 2 and 2 together but now I can see it was a basic form of rev hang and it really did slow down the upshifts. You could of course just bang it though but that would not be very kind to the drive line.
Now here's a thought. My Omex ECU can be set up for full throttle gear changes where it kills the spark when the clutch is hit at high revs.
I wonder???
"When I think back to my early experience with my old Zetec, I had forgotten that I used to feel that the gearshifts were slow because it took too much time for the engine to slow down on upshifts.
When I changed the ECU to Omex and was able to programme the IAV to my requirements, the gear change was much slicker because the IAV remained closed under those circumstances. In effect, slight but noticeable rev hang."
