Mini AFC 2.2 (used).
Mini AFC 2.2 (used). Used on a Cobalt SS 2.0 2005. Plug and play to fit OEM connectors. Bought from Easy Performance. Price new is about 160$, asking 100$. Cable is about 24 inches long which is nice to fit in engine bay. Comes with user manual. Pictures can be sent. Please send me a PM if interested. Thanks.

"The AFC 2.2 (Air/Fuel Controller) is a micro processor based air fuel calibration device with digital display. The AFC performs this recalibration by receiving the Mass Air Flow (MAF) sensor's frequency signal, digitally recalculating a modified MAF frequency value and passing this modified frequency to the Powertrain Control Module (PCM). The AFC - Version 2.2 can be setup to run in one of two modes - Standard Mode or Enhanced Mode. The AFC can be programmed to apply correction factors ranging from 1% to 255% of the original MAF signal. To elaborate on this, correction values less than 100% cause the PCM to perceive less air is entering the engine and it responds by commanding less fuel be delivered to the engine. Thus, AFC values less than 100 pull fuel from the engine. Conversely, correction values greater than 100% cause the PCM to perceive more air is entering the engine, causing it to command more fuel be delivered to the engine. This means AFC values greater than 100 add fuel to the engine.
Two separate operational modes are provided with the AFC 2.2. The current operational mode is announced briefly on the display during the AFC's boot up routine. The user can switch between operational modes on the fly without shutting off the car or resetting the AFC. Switching between operational modes as well as all editing is accomplished through the three interface buttons below the display. All set point editing is accomplished through these interface buttons. All data is automatically stored into memory when leaving any edit mode. This means all set point data is saved for subsequent system power ups.
Standard Mode - Applies a single correction factor to the entire frequency range (air flow range) of the MAF sensor. Thus, regardless of the MAF sensor's frequency signal sent to the AFC, the AFC will apply the same correction factor.
Enhanced Mode - This mode provides 13 independent set points that allow custom fueling curves to be programmed into the AFC. The enhanced mode sets these 13 points in even 1,000 Hz intervals starting at 1,000 Hz on the low end of the MAF's output range and all the way to 13,000 Hz at the high end of the MAF's range. For MAF values between these defined set points, the AFC linearly interpolates the output frequency using the bounding set point values. Thus, the AFC creates a smooth curve throughout the MAF sensor's output range.
The AFC is needed when the engine's fueling demands have been altered by changes performed to the engine induction system. When induction changes have changed the fueling demands, the OBDII Powertrain Control Module (PCM) typically responds by adjusting the Long Term Fuel Trims (LTFT). (Fueling Trim values are a adaptively learned parameter the PCM uses to make minor adjustments to the fueling parameters to obtain the target programmed air/fuel ratio.) This unit allows adjustments to the Mass Air Flow (MAF) sensor's calibration which impacts the fuel trims. With proper adjustments to the AFC, the LTFT values can be brought back near zero where the PCM functions optimally.
The AFC 2.2 provides external MAF recalibration capability throughout the MAF's entire flow range. There is no other product like this out on the market. This product alone eliminates the need to purchase expensive, custom calibrated MAF sensors. With custom calibrated MAF sensors, if the engine's configuration changes and alters the MAF calibration, then another MAF calibration must be purchased. With the AFC, the user can recalibrate the MAF exactly as needed without any further expense. In this way, the MAF can be fine tuned to the engine's configuration."

Yes, please look for AFC2.2 under Products, Powertrain on this web site:
Easy Performance Products
Mine look the same but the electric cable has been lengthened.
