Tdi Timing graph VCDS

Long shot but, anyone checked where they are?

This is a random shot from Google but it’s pretty much exactly where I am (ignoring fuel temp).

Reason for asking, curious if you’ve ever moved it to the blue line and how it affects running/starting.

More background, it’s all about getting start of injection required and actual to match and the duty cycle as low as possible.

With timing advanced up to the green line, actual and required are quite a way apart and the N108 duty cycle up around 50%.
(Measuring blocks 004).

Stuck down a rabbit hole of TDi injection!!!

There is a “interesting “ thread out there that deals with this.

TDI Timing Revisited

Sometimes it's good to have a refresher. I frequently get questions about optimizing mileage, or see threads about reduction in mileage after a timing belt change. This post addresses timing subtleties on VE cars, '96-'03 in North America. Firstly, here's a screen by screen, step by step...
