Midwest Turbo & Performance is a proud supplier of EFI guru John Meaney's Big Stuff BS3 PRO SEFI engine management systems. The BigStuff3 GEN3 PRO SEFI system is the first programmable powertrain control module for modern SEFI, Coil-on-Plug (COP) engines and electronic controlled transmissions. The GEN3 PRO SEFI system offers many unique features. Features such as dual Wide Band Oxygen (WB02) air/fuel ratio control, individual cylinder & spark compensation and onboard data acquisition are just the beginning!

The dual WBO2 functionality eliminates left and right bank base engine and transient fuel calibration guess work by providing accurate and consistent air/fuel ratio control (9.5:1 to 15.9:1). The on-board data acquisition feature allows selected powertrain management variables to be recorded in real-time as fast as 50 times a second, with 10-bit resolution, for up to 5.5 minutes. Once recorded, the data can be analyzed off-line with the BigCommsoftware.

These features, along with many others, make the GEN3 PRO SEFI system one of the most technologically advanced, cost effective SEFI powertrain management systems on the market. The GEN3 PRO SEFI system includes: A Powertrain Control Module (PCM) Main Wire Harness (MWH) Injector Wire Harness (IWH) WBO2 sensor BigComm Windows compatible calibration software 5' serial communication cable The intuitive BigComm software enables real-time calibration and measurement of all engine management control variables via a serial PC link. The GEN3 PRO SEFI electronics are housed in a black powder coated aluminum extruded enclosure with integrated rubber isolator mounting provisions. The aesthetically pleasing, nylon braided, MWH and IWH use OEM style Packard and TYCO terminals and connectors. Gold plated terminals are used for the (2) 6-way MWH-to-WBO2 connections. The GEN3 PRO SEFI aftermarket electronic fuel injection system is compatible with most GM style EFI sensors and actuators. The GEN3 PRO SEFI ECM can be software configured to be compatible with many OEM and aftermarket electronic and inductive pick-up (IPU) ignition systems
