ECM Titanium, the recalibration software for your workshop

Customization has no limits! In the Harley Davidson world, all kinds of customization are an integrating part of the brand’s philosophy. With ECM Titanium you can satisfy the demands of this vibrant market with a concrete solution to meet your customer’s needs.

The iconic twin-cylinder engine from the Milwaukee manufacturer, in all its displacement and power configurations, is a touchstone for enthusiasts not only because of its unmistakable sound. In fact, its specialty, in terms of performance, is the torque that is available even at low engine rpm.

Despite the mechanical simplicity of Harley engines, through targeted performance intervention, you can really change the character of your bike. Through the modification of a few engine management parameters, the increases in torque and power are very considerable. Especially on Euro 5 models, as in this case, working on the fuel injection and lambda maps leads to an effective power boost by adding fuel gains in the air/fuel ratio. Consequently, the high cubature of the engines will facilitate an important performance enhancement, starting with torque delivery. After this first step of intervention, you just have to tune the calibration: It’s the work for a specialist like you!

With ECM Titanium, we offer you the tool for easy and intuitive recalibration. Make the most out of it and give a totally customized experience to your customer.
