Remember, what you do to one bar the exact opposite happens to the rest. This is due to either going up in one bar (adding) and down in two bars or going down in one bar (subtracting) and up in two bars. By subtracting (-) to each bar in a row, you'll end up increasing the percentage for the proper ratio. By adding (+) to each bar in a row, you'll end up decreasing the percentage for the proper ratio. This will allow you to move from say 2% all the way to 18%.Ī quick note about adding (+) or subtracting (-). Do not add and subtract at this point, so pick one and stick with it. You level upwards by either adding (+) OR subtracting (-) to each bar going from left to right or right to left. The guess work is now done and all I have to do is level upwards with the tune. Now that I have balanced the bar graph and reached a proper ratio, getting to the optimum tune is easy. Always keep the three balanced bars together until you have all four bars balanced, like below. If this doesn't happen, either keep adding (+) to the unbalanced bar or do another set of subtractions (-) for the three balanced bars. This leveled all four bars out to the same point. Within a few clicks, I had balanced three of the four bars.įrom here, I subtracted (-) once from each of the three balanced bars and then added (+) twice to the unbalanced bar. It's important to understand that when you add (+) or subtract (-) to one bar, the exact opposite happens to all the rest.

My initial tuning was done and I could now focus on the optimum tune.įor ECU's, due to having four bars it can take longer to reach a balanced state. From the initial tune, I added (+) to the right column and then subtracted (-) to the left column and reached a balanced point of 8%. This will require adding (+) or subtracting (-) randomly to each of the bars in order to get to a balanced state.įor Carburetors, you should be able to balance out the three bars with three or four operations.

In order to reach the optimum tune using the solution in this guide, the tune has to reach a proper ratio of any percentage. Below is an example of an initial tune for each tuning tool. When you reach a potential balanced point with the tune, the tool will say proper ratio in the lower right corner.

The carburetor tuning tool has three bars that have to be balanced and the ECU tuning tool has four bars that have to be balanced. Depending on the vehicle, it will need to have the carburetor(s) or the ECU tuned in the appropriate mini-game.
