I highly recommend if you have an intake and e. Stock ECUs generally are far from optimal and are developed to allow for a wide range of riding styles, fuel quality.
#Grom ecu tuning code
It ties everything together and gives your engine that perfect mixture of fuel and air necessary to achieve optimum performance levels. I finally got my ECU back from DHMotoring My bike feels 100x times better now that I have a tune on the bike. ECU ReFlashing, in general terms, is a method of erasing the ECU’s program code (instructions) and reprogramming the vehicles ECU’s Flash Memory with altered program code, thereby changing how the ECU will respond to inputs. In other words, a fuel controller is your cherry on top. While it is certainly possible to change your intake and exhaust without spending the extra cash on a fuel controller, (1) you run the the risk of starving your engine of fuel, or ‘leaning it out’ causing it to run hotter than it should which can ultimately cause engine failure, and (2) running a fuel controller is the only way to maximize the performance improvements from your other modifications. These modified fuel maps tell your injectors to produce more fuel, which complements the additional air flowing through the cylinder thanks to your other mods. What exactly does a fuel controller do? Well, remember our earlier conversation about more air in + more air out = more power? There is one additional factor to the equation: more fuel.Įssentially, fuel controllers communicate with your engine control unit to alter the signals sent to your fuel injectors using fuel maps. While it isn’t the the sexiest thing on the list, a fuel controller is definitely something you should consider picking up if you’re serious about getting more power out of your Grom.
