Hello,

I have problem with my new injectors adjustment. I set my KRKTE to 0.086 and my tvub to according to this table I've found:

6V -> 3,80 ms
7V -> 2,95 ms
8V -> 2,33 ms
9V -> 1,93 ms
10V -> 1,62 ms
11V -> 1,39 ms
12V -> 1,20 ms
13V -> 1,05 ms
14V -> 0,92 ms
15V -> 0,82 ms

But this TVUB seems to be wrong, because i get like -20% stft idle and part throttle and about (-6%)-(-10%) WOT. Has anybody adjested this injectors and has correct tvub?

Hi,
It has been a long time but wanted to know if you found the solution ? I'm pretty sure this data are coming directly from a Saab ecu so I think they should be ok. Saab ecu is very different so maybe their injector driver adds some addional lag compared to the motronic.

Are you sure that the Saab is actually running the same fuel pressure?

Saab FPR is 3 bar. I checked the values in a Saab 9-3 bin and they are fine.
