Zafira 1.7 CDTI DTR DENSO STAGE2

Postby marcin37 » Thu Dec 01, 2022 2:20 pm

hi...
I need help in making a stage 2 map in my Opel. What is done: chiptuning stage 1 150hp, DPF removed, EGR removed, exhaust cooler removed.
Now I made a turbo increased compression circle and a larger intercooler.
Can we make a map for 200hp and 400Nm?

Does the pressure sensor in 1.7 see only 255kpa? is this a 300kpa sensor?

Why at 2200RPM I have 225kpa of pressure and then it starts to drop at 3700rpm I only have 232kpa?

Similarly, the pressure on the CR ramp increases and at some point it decreases and increases again.
