I have a k&n filter and a jardine exhaust I don't know how to remap my ecm... ive read on here somewhere that I need to but I don't have emcspy or a cable nor have I ever done anything like this before, everything else ive ever worked on was carbureted... any and all help would be awesome, the more dumbed down and step by step the better... I know it needs remapped its not running exactly right It runs ok when running fast but when cruising it hesitates and spudders.
