Description - This is a good used ECU from a 2018 KTM 350 XCF with 85.9 hours.  This should fit 2017-2018  KTM 350 SXF/XCF,  Husky FC350, and Husky FX350.  I'm sure this would work for other 350 years and models,  but the map is specific to SXF/XCF.  This will not work for 250's, 450's, 500's,  501's.  The ignition map,  fuel map,  and rev limit will be wrong. (you could have it remapped though) Please message me if you're not sure about fit,  if you contact me, I can guarantee fit.
