could someone make a self-test of the reflash of the ecu and the change of the exhaust, that is to say to test before and after the changes how many seconds are won or not, I think it would not be interesting a test of 0-100kmh or 0-60 mph , it would not be interesting maximum speed either. It seems to me that a measurement that would contribute something would be 40-140kmh //// 25-95 mph in a single gear, for example 4th gear, where torque and hp would be mixed and really see what is improved by a certain change ( ecu, exhaust, ecu + exhaust, fuel, etc) with a single gear, we would leave the variable side if the gear change is more or less fast, and let us carry the chronometer in the left hand. neither can we compare between users because there are other variables (user weight, tires, height above sea level, engine wear, fuel) ..... but if everyone does it, respecting the same conditions of the test, it would be a useful data to share. the idea came to me when I saw a graph of yoshimura comparing the gain of almost 2 hp but at 8000rpm .... then I asked if there really was a gain in seconds or was the "sensation" ... it's like the chronometer does not lie . I usually do it with my vehicles, in the same place on the route, between 2 signs and you can tell the difference in time if it goes with 2 passengers or with a new tire and the same one with half use. I think it would be an interesting contribution made by the same users.
