bozo

I am boosting 1.5Vtec euro model. I do not have original base map so I have to use the closest and that is d16y8 or d16z6. But I have bad idile and the car is fuul of flat spots in low and high cam. How do I corect that?
Do I add fuel o cut it? Is timing the same?

dont tune your car without any other tuning capabilities besides guessing... get wideband or get to a dyno..

its just a d, guess all you want
add timing in the flat spots and see what happens
