The new 3.0 CR-Fueler is loaded with many new features!

The heart of our new 3.0 controller kits is the plug and play interface module. This module allows you to unplug the harness at the stock ECM, plug that into the 3.0 module, and then plug the module into the stock ECM. With this module, we are able to get all of the major signals needed without the need of a large harness that snakes all over the engine bay. We also get these signals directly, not over CAN like some others. We tested that method years ago and found it was not reliable enough for the critical signals for a secondary ECU.

The new 3.0 interface now features user selectable upgrades included on board. 

Those options include:

Spark control

Traction control via wheel speed sensor data

Spark/fuel torque management 

Throttle control

You can mix and match what options you want to utilize and are no cost upgrades included in all kits!


The plug-and-play CR-Fueler is a port injection controller that adds a secondary set of 8 (or more) port injectors to increase the overall fueling capacity. This allows for higher ethanol mixtures, more boost, and safer, more reliable horsepower. It can be configured with many options, with coverage of ALL GM V8 direct injection equipped vehicles from 2014-2023. Including L83, L84, L86, L87, LT1, LT2, LT4 and LT5 engines.


As an added benefit to the port injection, the fuel being sprayed onto the intake port walls and valves, will clean the harmful deposits that will build up in Direct Injection only engines intake tract.

All of this at a much better value then larger Direct Injection High Pressure Fuel Pumps or injectors, with no idle or low speed driveablity issues that can be associated with those parts.


CR-Fueler 3.0 FT600 Kit INCLUDES:

  • Fueltech FT600 ECU: The FT600 ECU is our most advanced engine control and monitoring system. This top of the line ECU is capable of managing sequential injection and ignition on engines from 1 to 12 cylinders, or up to 4 rotors, and accommodates up to 20 inputs and 32 outputs. The FT600 offers the features and capabilities offered by the FT450 and FT550 models and more! Housed in an extremely durable aluminum case, the upgraded design also includes an upper visor to reduce glare and houses 10 LED lights with adjustable color and intensity, ideal for a progressive shift light. 4 adjustable LED lights, 2 on each side of the screen, that can be configured for alerts or to show the current status of any sensor. The 4.3” color touchscreen has been upgraded with an anti-glare display, integrated digital dashboard, 4 programmable display screens, and a customizable splash screen. The FT600 features dual 34 pin SuperSeal connectors, 2 CAN Bus ports, and USB-A mini. Equipped with FTManager software and an impressive list of features, including sequential injection and ignition, O2 closed loop, active traction control, integrated boost controller, internal datalogger, progressive and PRO-Nitrous controls, odometers, drag racing features, electronic throttle control, inclinometer gauge, integrated GearController with strain gauge sensor on the shifter for more efficient gear shift cuts, built-in accelerometer (G-meter), gyroscope, and more!
