Buell, X1/S3 Race ECM. This ECM comes with a stock calibrated fuel map from Buell. You can ask us to program it for your setup send me a e-mail at: dris@twinmotorcycles.nl

This race module provides an advance curve that allows the engine to rev to 6800 RPM. Module designed to work with other race system components to achieve improved torque and horsepower. Fits '99-later X1 and S3/S3T models.

Be aware that we skipped a lot of exhaust manufacturers from our website becuase off poor performance or poor quality, and we are not going to make new fuelmaps anymore for exhaust that we don't have in our list. This is a 5 day job, when you pay us we do it for you, you only need to send us your exhaust.

So always first mail us if we have your setup.

We Guarantee 200% very good running bike with our Torque Hammer exhaust line.
