Hi people i really need your help,
My seat ibiza (SIMOS PCR2.1) is tunned, have +/-140cv, 310nm and egr /dpf off. I know that the file is modified by swiftec.
This is the second time that is happening, and the problem is; when i introduce the file modified the car works good for +/- 500km, after that the car start with many problems.
Engine idle and stop 0.2lt (car working good 0.5), no power, and engine wants going down all the time on 1º gear, ecu is very confused, don't have erros on dashboard.
How knows what is the problem.
This file is a second original of Seat.
Thanks
