The R-FIT is a full featured fuel controller applicable to most vehicles. It is equally effective on N/A engines with basic bolt-ons to turbocharged cars modified with higher boost. It is very important that cars with such modifications also have the fuel demands altered to prevent potential engine damage or detonation. It will assist the factory ECU in keeping the proper air-fuel ratios. The R-FIT makes this possible without the need for a full remapping of the car's ECU. The R-FIT has many different settings, which can be calibrated and used in accordance with the vehicle's set up. Once different fuel levels are matched to the engine modifications, changing between octane's and different boost levels is easy, as the device has two programmable channels. With a total for 64 maps that can be saved on one unit. Data is displayed in several styles and shows different parameters such as airflow voltage, induction pressure (MAP Type Sensors only) and engine speed as well as the fuel correction settings. Setup is straightforward with an easy configuration for air flow sensor type and engine cylinder size. Fuel control calibration allows injector pulse width duration to be increased and decreased by up to 50%, within a user defined 16 point range in 100rpm increments. Settings can also be transferred from one R-FIT to another through the infrared port on the side of the unit. When used in conjunction with the R-VIT, (Sold separately) two more data options can be displayed on the R-FIT plus an Anti-stall feature for turbocharged vehicles is available. Using the R-VIT also makes installation easier for the R-FIT due to the fact that the RPM signal can be sent via infrared port and less wiring is needed.

Easy to install, ultra compact full featured fuel controller. Can be used on most cars using Hotwire, Flap, Karman, and MAP type air flow sensors with an easy calibration mode for most vehicles. (Mechanical/technical skills and knowledge of the car is required) User defined 16 rpm point range of adjustment down to 100 rpm increments. Will adjust + or - 50% of injector pulse width down to 1 %. (Within the parameters of the injector and air flow sensor) Can monitor and display air flow voltage, air flow voltage compensation rate, induction pressure (MAP sensor only) and RPM. The ability to store multiple maps for a wide variety of settings, 2 programmable channels 1, 2 and PASS function. PASS is a bypass which is the same as turning off the R-FIT (No adjustments) Up to 64 maps can be stored in one unit for using different fuel maps with a variety of octane fuel or different boost levels Peak hold data display, visual, audible warnings, contrast and brightness adjustments When set to monitor RPM it has an audible and visual shift warning indicator Four different displays/Multi-view graphics. Unless it is reset it retains all data settings in memory, even if battery is disconnected, Master Reset to change all settings back to factory configuration. Data lock to prevent unwanted changes to settings, and Utilizing the infrared port the R-FIT can copy and save data from one unit to another. (Cloning function) Used in conjunction with the R-VIT, (Sold separately) two more data options can be displayed and an Anti-stall feature for turbocharged vehicles is available.
