lol, its a good tool, if you dont use regular pump fuel , here i use 99 ron fuel, but the standard is 95, the engine is made and designed in japan where the regular fuel is 102 ron and the the engine timing is rertarded to use the low grade fuel of and of the market countries, so being able to set up the ignition advancement to suit the fuel you use is great, my ignition module was set between 3 and 5 degrees at various points int the rev range and throttle positions , and and extra 10 bhp , for a couple hundred pounds or dollars, what else has this sort of bhp per $, with the ease of fitting!!
