Sure there are things it cant do, but there's plenty it can do very well, it just needs to be set up and made right by someone who knows them and can use it properly. Most running issues I see on Weber, are from bad looms, with noise and low voltage under load, or just badly set up and tuned. You would probably get just the same poor results if you had those issues on aftermarket, but in changing to aftermarket you are fixing them!


Lets see how the new ecus perform is 25years.
