Our Ultimate ECMSpy USB Cable is the first cable in the World to have the USB Module embedded in a Deutsch Backshell.  This is possible becasue of our Proprietary EAS™ Technology and is Exclusive to only ECMCables.com Products Made By CalFABco.  EAS™ Technology provides Destruction-Proof TECHNOLOGY which prevents the cable from being broken away from the Deutsch Connector when disconnecting the cable. No other competing cable has this feature.

As all of our prior cable products our Ultimate ECMSpy USB Cable is designed to connect Buell’s 99-08 including X1, ST FI models, and all XB9 and XB12 models' ECM to a PC or other Smart Devices for Engine Performance Tuning. Our UNIQUE design  implements a TRUE USB CABLE which is the only one that provides USB TECHNOLOGY's Differential Pair Signaling to ensure transmitted data is protected and secure for either endpoint. As per our prior cable revisions which used Serial (RS-232 TTL) Signaling, we've also included a "Shielded Cable" solution in this new USB Cable to combat both EMI and extraneous power surge interference that affect unshielded cable conductors in high-noise (electrical interference) ECM Tuning environments. Combining this "Shielded ECM cable" with Tuning software such as ECMSpy or TunerPro RT, provides a higher degree of accuracy when optimizing Buell Engine Performance.

This product can be used with ECM based Optimizing Software. Software sold separately. No Software is included with this product. Refer to ECMSpy or TunerPro RT websites for more details. Compatible with Microsoft Windows XP/Vista/Win7/8/8.1/10.

Our U-Class based products have been designed and tested for real-world applications; specifically for use in harsh environments, and under rugged and extreme conditions regardless of the application for which they’re being deployed. Our Ultimate ECMSpy USB Cable  has similar tests results as those of our other EAS™ Technology equipped cables which can withstand longitudinal tensile forces in excess of 35lbs, wherein these linear forces would normally tear wire conductors from pins, should the connectors remain intact.
