Golf 4 1.9 TDI AHF Stage 2

Postby a1rwalk » Wed Jul 11, 2018 8:52 pm

Hello, I want to rate my stage 2 remap of a VW Golf 4 1.9 TDI AHF 110hp with a turbo from 131 PD and 0.240 nozzles.
I don't have the original file anymore but I'll upload a similar one.
I tried it and there is lots of smoke and I think that I could get more power from this setup.Could you please give me some advices?

As far as I can see it shouldn't smoke, your smoke maps are very conservative.

Is it black smoke? Also, it seems to me that your holding out too much boost up the higher RPM for the PD130 turbo.

From what I hear safe pressure @ 4000RPM is 1450mb, and if possible it should be standard pressure afterwards. I didn't look too much at anything else.

Yes, it is a black smoke, but the car is straight pipe so it could be from this.I will reduce the boost pressure in higher RPM.I want to know how to tune the pump voltage map properly.I increased the on highes mg's the voltage with around 0,2V.
