Hi
I have 2004 1.9 tdi 81kw Seat leon.
I have problem with timing on 12mm pre stroke head.
I replaced my 10mm zero pre stroke pump head to 12mm pre stroke head. At first I set injection timing using vcds to blue line on a timing graph. But it was to retarded, so I advanced it 7-8 degrees (vcds shows 8 degrees BTDC). But it is still hard cold start (-20 degrees) it takes 10-20 sec to engine stop stuttering, after that engine runs very smooth.
Now I advabced it 14 degrees, I will see in morning how it is.
Is that right when timing is out of the graph then ECU does not advance timing on driving?
Does injector number 3 measures needle lift from zero? So it shows pre stroke not main injection?
Can I make delay in to the needle lift zensor?
