Having just replaced the quantity adjuster seals, performed the Hammer procedure to adjust IQ and having read a lot here about it, I am still wondering just what Injection Quantity is. The units are mg/stk which I assume is milligrams of fuel injected to a cylinder per pump plunger stroke(?). However, I have read here in several places that lower values or IQ equate to "more fuel", and vice versa, which seems contradictory. Also, it appears that installation of larger injectors requires a higher setting of IQ for some reason.
Can anyone please give a tutorial on what IQ actually means and does or point me to a source of further info (my attempts of searching here did not provide much detail).
