UTCIS™ Engine Management (Patent Pending)
Bosch's CIS-K, or K-Jetronic, fuel injection, a variant of the popular Continuous Injection System (CIS) family, is found on many makes of vehicles including: Audi, BMW, DeLorean, Ferrari,Mercedes-Benz, Peugeot, Porsche, Saab, Volkswagon, and Volvo. The UTCIS™ Engine Management System from UnwiredTools consists of a hardware and a software component. The UTCIS™ hardware component installs in place of the OEM Warm-Up Regulator - it replaces Bosch Warm-Up Regulators used on K-Jetronic™ (with and without Lambda) Gasoline Fuel Injected Engines. The software component of the UTCIS™ brings modern engine management to these fine older cars without the cost or complexity of Electronic Fuel Injection conversions.
Two different versions of the UTCIS™ product family are available offering graduated engine management functionality to meet the needs of the numerous CIS applications. All UTCIS™ products are user-programmable with the freely available UTCIS Engine Management Software™.
Note: Starting with the G7 revision of our UTCIS™ products (Spring 2016), we no longer ship the units with a USB connector. To program a unit, you will require a UTCIS™ Programming Adapter.
UnwiredTools ships your unit pre-configured for your specific application and you generally do not need to perform any programming steps. In the event that you desire to custom-tune your unit, you will require the programming adapter. For more information, please contact support@unwiredtools.com.
Like all UnwiredTools Automotive products, each UTCIS™ product comes with our limited One Year Warranty.
Our UTCIS products are generically known as a "Digital WUR"
UTCIS-V™
Warm-Up Regulator for normally aspirated engines. This version includes a Manifold Air Pressure (MAP) Sensor for pressure < 1 bar (ie vacuum). This product is a step up from our UTCIS-V™ product and offers intermediate engine management programmability. This programmability permits the tuner to maximize economy or performance. This product is perfect for normally aspirated performance engines. more ...
UTCIS-PT™
Warm-Up Regulator for turbo equipped and racing engines. This version includes an RPM sensor and MAP Sensor for pressure over and under 1 bar. Advanced engine management programmability. more ...
