Why Buy from Us?

Better Products - Higher Performance - Quality Built ...and Priced just Right!

We strive to develop, produce and market high-quality, affordable, and durable products based on varying Serial Communication Protocols, having a specific purpose or use requirement; as do all our current and future ECM connectivity products.

Featuring World Class Technology

  EAS™ Technology

eas™ logo products are made with calFABco’s proprietary Encapsulated Anti-Stress ™ technology ; EAS™. This feature alone, sets our products apart from other functionally and aesthetically similar products. The advantage of incorporating EAS™ within the wiring design is two-fold; the first being the ability for cable assemblies having side-by-side signal and power requirements for consumer-grade configurations which transition to industrial and commercial grade wiring for use with significantly larger wire gauge conductors and crimp terminals to accommodate existing OEM mating to connectorization requirements. The second advantage, having equal significance and benefit, is that of the EAS™ transitioning method, provisions Cable and Dongle products to withstand higher than normal stress and strain forces which would in most cases cause a failure at the point of termination. These forces, would in all cases induce failure due to separation, shearing, or breaking apart, if not using and EAS™-based solution.

Shielded Solution

Stripped Wire Showing Shield Within Wire

Our products implement a "Shielded Cable" solution to combat both EMI and extraneous power surge interference that affect unshielded cable conductors in high-noise (electrical interference) ECM Tuning environments and provide a higher degree of accuracy when optimizing Motorcycle Engine Performance. No known competitor declares use of a "Shielded" implementation, and none provide transition capabilities from varying wire gauges to connector assemblies.

Recertified products help save money when buying an ECM Cable. Our recertified or refurbished products started out as either Customer Returns (RMA), or production units that did not initially pass QA inspection. These items may have minor cosmetic issues (scratches, etc.) which do not affect the performance of the unit, and carry the same warranty, and same return policy, as our NEW products. Recertified items are available ONLY from OUR on-line stores, for a limited time, and only while supplies last. Since these products are sold at a substantially reduced price, discounts or other special offers do not apply.

Commercial Grade
