DSG remap on sale in the USA

Yeah the stage 3 seems a bit pointless to me, if it makes D mode anything like S then it would be a step backwards IMO.
I know that they play around with the clutch engagement points and pressure etc so it does make the shift faster

You are partly right Stiggy.
The 350nm rating of the DSG box is there for the longevity of the 'box. Increasing the torque through the 'box will inevitably reduce the lifespan of it. Slippage occurs due to the regulation of the clamping pressure and the pressure can be altered with remapping. The components withing the 'box should be okay to 400bhp and similar torque as in the original link. :smiley:

I see now, I think - so nothing to do with the mechanical switching of the gears. On upshift, the 'box kind of drags the clutch a little, dialling in the power gradually to make a smooth transition. The HPA speeds up this transition process so full power can be applied quicker, thus making faster shifts that way?
I agree on the S mode too, it's too frantic and I can't get used to it. I just use D for docile and M for manic. :happy2:
jonnyc:
Yeah thats about it mate :happy2: The power is reduced as you approach the red line too, and power is gradually fed in (very fast) but still not full power right after the gear change is made..
Should make it a lot more aggressive, whilst still being smooth.. :laugh:

Interesting, so could the reason I see power tail off on a RR graph be because of the DSG limiting instead of, as I thought, the turbo running out of puff? Meaning the increase in redline might actually be of benefit??
