Ecutek manages it different than Cobb though. It's supposed to be safer because it doesn't cut fuel.We have been REALLY happy with the Lachute Performance EcuTek Flat Foot Shifting feature. It has always been silky smooth and rather non-violent. It did take some getting used to, but so far, we have not had any concerns after the thousands of street miles and very hard track miles with our pro-drivers.
Our rev-matching feature also worked surprisingly well! With all this newer technology, it's amazing how it takes some adjustment in muscle memory to cater to the new tune features.
