Curious behavior depending on auto vs manual DSG mode (2018 R)

I respectfully disagree that “all automatics have done this...”

I have owned a variety of torque converter and dual clutch cars from Japan, Germany, and domestic. None of them have exhibited anywhere near this behavior. The cutout post-shift is not subtle. It’s a full second to second plus of no torque. Other cars that do a cutout to aid in the shift do excatly that - *during* the shift either fuel or spark is cut, not after the shift is fully complete.

I think it more resembles a mis-calibration where the ECU thinks something is past a safety threshold.

Wow 18R here not unhappy like I’m hearing here.

So S mode shifting itself there’s a slight spark interrupt on the gearchange to limit power on the shift. M mode shifts great no interrupt.

Only thing I notice is if you go wot fast it feels like it kills the power like turning the key off to make the gearchange. Thought it was meant that way. Now I found if you slowly go to wot it’s almost gone or much better.



I took it to the track bone stock 13.19@103 then loaded a map6 JB4 12.52@108 was quite pleased.

I'm Eurodyne Stage 2 and notice the same thing....Someone PLEASE come out with a home tuning solution for DSG, the delay in tuning is ridiculous.

I guess I was misunderstanding the mannerisms. It should do it during the shift. Never after it is complete.

Uni just released their TCU tune so hopefully it corrects the issue...
