hi Doc Diesel, i myself personally appreciate your concern for the fact that zero talaga ako theoretically sa makina. i suspect the information involved would be a massive one but is it possible for you to draw up a calibration basics first (like in a nutshell) para nga maintindihan ko, in layman's terms? and then progressively, we can go on with the problems and symptoms and on with solutions, etc.
in my case, somebody told me that my 4m40 ay medyo malakas ang konsumo and maybe needs calibration or something. isa pa, when i press on the accelerator, hindi agad umaarangkada, there's a delay bago mag-pick-up.
