Motech mapped DSG 'hesitation' after gear change - FIXED. R-TECH Reign supreme
PDT:
Revo Software has no issues, The only software I see with this issue is from smaller independant tuners.
I have had 2 cars with this issue on our own map, Keano on here was one of them but after a few hours we got it solved. ECU was limiting torque and shift was delayed, DSG cars have more maps for torque limitation than manuals, its just a matter of finding them.
Have never had a Revo tune cause this problem.

Its not the shift that is delayed. The shift is instant. But it then takes .5 of a second for the boost to kick back in.
Like I said though I drove Motechs own car and there was no such 'hesitation' after the gear change.

To be clear the torque limit I have issue with is the post up-shift torque dwell, not the in gear element. The peak torque on a dyno run is still being modulated by the DSG gearbox (which I accept) at around 280 lb/ft.
I will draw a crude graph to show what I mean.
The reason it bugs me is that it totally negates the benefit of the DSG - I'm far from a driving legend, but the torque interuption I introduce when shifting my manaul track car is seemingly less noticeable, though I've not quantified this with a Vbox or similar. I know from driving the other day with a friend in a fairly spirited manner, that when my car changes gear he pulls on me in a way that shouldn't happen.
As I exhausted conversation (a while ago) regarding the map being the cause the torque-dwell, I don't mind disclosing that it is a Shark map on my car, as Heavyd has eluded to.

Two DSG cars with the same issue using the same map IMO proves it must be the map.
I also wouldnt be happy with torque staying at 280lbft. Whats the point of having stage 2+ if the torque is lopped off at 280lbft. Thats stage 1 territory
alackofspeed:
Not sure if I mentioned it, but mine is a STG 1. 280lb/ft of torque is fine..... if it was delivered properly after a gear change. As it is, it ramps in for about 0.5 seconds post gearchange. It's most notable on part throttle or you manually change at high torque (say 4000rpm).
PDT has been very forthcoming with offline conversations on the matter. With a bit of luck I'll get it sorted.
