NexGen FMIC + CAN Flex Fuel: How the Systems Work Together

NexGen Stage 2 + CAN Flex Fuel combines the cooling and boost capability of the NexGen front mount intercooler system with the fuel composition flexibility of the CAN Flex Fuel sensor. The NexGen FMIC moves charge air cooling to the front bumper opening where ambient airflow keeps temperatures dramatically lower than the factory TMIC. The CAN Flex Fuel sensor measures the actual ethanol content of the fuel continuously and communicates that reading to the Accessport via the CAN bus the ECU map adjusts fueling, timing, and boost targets automatically based on what the sensor reads. On the NexGen Stage 2 hardware with E30 or higher ethanol content, the Stage 2+ CAN Flex Fuel OTS maps can target substantially higher boost and more aggressive ignition timing than the 93-octane Stage 2 configuration, because the combination of FMIC charge air cooling and ethanol's knock resistance properties allows the calibration to be significantly more aggressive.

Stage 2+ Flex Fuel OTS Maps and Dynamic Calibration on E30/E85

The Stage 2+ CAN Flex Fuel OTS maps are calibrated for the complete NexGen hardware configuration with flex fuel capability not adapted from Stage 2 gasoline maps, but independently developed calibrations that account for the FMIC's lower charge temperatures, the intake's improved airflow, the NexGen solenoid's boost control precision, and the ethanol sensor's dynamic input together. Running E30 through this system on the NexGen Stage 2 hardware produces meaningfully more power than the same hardware on 93 octane, and more than E30 on a TMIC-limited Stage 1 configuration the combination of front-mount intercooler cooling capacity and ethanol's knock resistance multiplies each other's benefits.
