10-cent tuning also for Opel DTI?

Hello,
Can I also use the 10ent for an Opel DTI?
I was offered a 2000 model for €5000, with only 8o kilometers and full equipment, except for leather seats and navigation.
IS THAT OKAY?
In my opinion, yes, it should just be a matter of figuring out where to connect the resistor.
OR?

I believe that Opel's direct injection (DTI) engines use VP44 distributor injection pumps with an integrated control unit.
The 10-ent solution only works with VP37 engines, specifically the 1.9L 4-cylinder models.
and VP?? - 2.5L 5-cylinder.
But I'm not sure about that.
