You have to let your ECU adapt itself to the new situation arising out of the modification. You should be well versed with the vital art of resetting the ECU of your car. The ECU has to operate on the newly acquired data as this new data reflects the true conditions post modification. You should then feed in fresh data pertaining to the conditions that have come into existence post modification. The moment you have carried out the modification you should purge out existing data in your ECU’s memory. This is the reason why ECU resetting is essential for optimum performance after any modification has been carried out in your car.
This means that you have to erase the old data from memory and new data pertaining to post modification should be logged into the ECU memory by mapping in new readings. The input data to the ECU should pertain to the post modification situation of the components and parts introduced, while making the modification. This old data no longer is credible as it pertains to conditions that existed before the modification. Thus the ECU in order to make accurate diagnosis on engine control utilizes stored data.Įven though you have made modifications in your car, the ECU still continues to get an input of the old data which is stored in it’s memory. The ECU tells your engine not only what to do but also how to do it. The ECU shuffles through the tons of data that come to it in the form of readings to decide the course of action that should be taken by the engine to ensure an ideal drive. The computer uses the mapped data to work out the optimum control conditions in which the engine should function. Whenever you make a physical intervention the data pertaining to such intervention gets recorded in the memory banks of your car’s computer. Nowadays sophisticated technology is being incorporated in the form of computerized controls that guide and ensure Engine performance. Modern day cars do not have manual controls. This is the only way to ensure that you get the best in both driving as well as handling. For your car to deliver it’s best performance you have to keep it in a fit condition at all times.
