TooHighPsi has teamed up with the controller experts at MOTIV to release an affordable plug and play solution - delivering sequential hybrid port injection for your GM Gen V engines!
LATEST UPDATE - Closed Loop Lambda Control has released - all boxes are now shipped with this new feature!
Current Users see download link below to update your controller.
NOTE: Image is for reference only - does not reflect the actual LT plug and play harness.
The MOTIV ReFlex+ is a versatile controller that has now been configured specifically for the GM Gen V engine family (hardware and software). This system utilizes the vehicle's high speed CAN bus to acquire the majority of the inputs required to control the hybrid port injection for an easy install with minimal connections.
C7 Corvette Installation video is here.
Camaro/CTSV Installation video is here.
INSTALL UPDATE: for Camaro/CTSV when running headers do not mount the reflex in location originally shown in video. Mount the Reflex+ in passengers side inner fender behind headlight assemble. Headers deliver a higher radiant heat load to the Reflex+ Enclosure and could cause it to exceed maximum operating temperature.
Reflex + for LT features include:
- 8 Cylinder Sequential Port Injection Controller
- MAF controlled fueling that utilizes the same calculation techniques as the E92 Powertrain controller, resulting in easy tuning and perfect control of A/F ratio across all operating points.
- Closed Loop Lambda Feedback for optimal fueling control under all conditions.
- Advanced I/O Integration via CANbus with four additional outputs and four additional inputs.
- Plug and Play harness utilizing USCAR injector connectors (add adaptors at checkout if you have the Jetronic Square Plug injectors)
ReFlex+ has additional outputs that can be configured and mapped to output on/off, digital, analog, frequency, and/or PWM signals for control over performance modifications such as:
Methanol Injection Kits
Nitrous Kits
Boost Control
Fuel Pumps
Relay Triggers
