Could be. On the stock tune the revs drop way too slow and there is almost always a rough 1-2-3 shift.Don’t wait, just shift and all will be smooth. Unless our euros are programmed differently … ?

Yes I’ve noticed this as well. Makes me wonder if the strategy is to prefer rpm to be a little high vs a little low on upshift in the case the car is being wound out through gears. I will ignorantly speculate as to why: I think it makes more sense to slow the engine a little at mesh vs accelerating it with respect to fuel and timing controls. Well outside my expertise though.There is a bit of rev hang still after WOT runs, but its very diminished vs. the stock software.

You might be on to something though. Because the shift is only smooth when the engine speed slows. Either that or the GT350 throttle body helps with with throttle response which resolves the rough shifting. Because whether you shift early in the rpm range or take it to near redline it usually results in a rough shift if you don't wait until the engine speed slows a bit before getting back on it.Yes I’ve noticed this as well.

Oh interesting. Care to elaborate or point me somewhere? I’m curious how that’s related.Its a cat protection feature.

That could also be a result of engine and wheel speed not being matched at the moment you get back on throttle. I do that plenty when I’m winding it out and shifting aggressively at redline, still a skill I don’t have mastered.You might be on to something though.

Turns out it’s easy enough to find something related online. Here’s a blog post copying an interview from Autoweek. I got about 5 search hits all with the same wording It covers VW emissions with manuals and how rev hang can avoid lean air/fuel conditions and reduce NOx.Thats what Ford Racing told me...I was a little disappointed that it was still there, not as bad as the OEM software but still there. I will see if I can find the email.
What are you using to see that?There is a setting that can be toggled in the ECM to turn rev hang on/off if I am reading it correctly....
Ah yes I will have to rewatch that.Rev hang explained:
HP Tuners. It is from my Ford Performance tune file, I would have to dig deeper to see if any parameters can be changed...What are you using to see that?
