Hello, I'm from spain and I have a z20ler 200cv
I have set the EDS stage 1 235cv in my z20ler. MY car is pulled between 3500rpm - 5000rpm.
EDS told me that the solution is to change the spark plugs.
I want to say to me that I must mount spark plugs (make and model for the engine z20ler)
This is a picture of my mods
I'm very worried because my car is not right ...
I hope someone help me,Thanks
