https://webspace.utexas.edu/xssive/IMG_1860.jpg Don't worry about having to use a drive by wire throttlebody stock ls2 ecm. This solves it all for you conversion / swap guys. MSD Mefi 4b System for an ls2 MSD # 240021. For an LS2 58x 6.0L/LS7 7.0L w/Bosch Style Inj This is a fully programmable efi system on the same level as Big Stuff # and Accel Gen 7. It has full wideband integration, and even direct hookups for Racepak dashes. Control table has tabs to click, main fuel tables from 0 -1,200 RPM, 1,200 -3,600 RPM, 3,600-6,000 RPM, and 6,000 - 9,000 RPM. Additional Main Fuel tabs control Boost Fuel, Compensation for temperature control, Intake Air temperature control, and Altitude compensation control. Spark Control tables are adjustable in the same RPM ranges as the Main Fuel tables. Another feature is the Knock tab to enable or disable the knock sensor, and change the knock attack and decay rates to Fast, Medium, and Slow, or completely disable the knock functions. Idle Speed Control tables are based on engine temperature, minimum throttle position and a calibration function that allows the ECU to determine when the idle spark stabilization, IAC and stall saver functions occur. Basic idle functions are set up from the camshaft profile; either stock or an AS&M camshaft can be selected. Setup tables let you select the type of ignition system you are running. GM HEI, Coil Near Plug ignition system. Sensor selections include 1-BAR, 2-BAR manifold absolute pressure (MAP), and intake air temperature (IAT). Fuel pump prime time allows the time in seconds that the fuel pump runs when the ignition is turned on. Rev Limit is based on engine temperature and is adjustable from -40 degrees F through 284 degrees F. Chart Function can data log any engine function controlled by the ECU, including engine speed, boost pressure, spark timing, knock and injector pulse width. You select and record the functions you want to monitor.

Its brand new, never installed. Looking for 1700$ shipped!!! https://webspace.utexas.edu/xssive/IMG_1861.jpg https://webspace.utexas.edu/xssive/IMG_1862.jpg New in the box RC Engineering 75 lb. (at 43.5 psi) injectors. That translated to 88lb injectors at 58 psi. THey come with the flow sheet direct from RC Eng. These are some of the largest high impedance injectors available. These retail for 98.75$ EACH (http://www.rceng.com/Saturated-Injec...750-P63C6.aspx). Looking for 575$ for the set https://webspace.utexas.edu/xssive/IMG_1863.jpg https://webspace.utexas.edu/xssive/IMG_1864.jpg Brand new Magnafuel MP-4303 750 Series Efi pump. This pump is rated at 2000+hp and over 120 psi. Its a beast of a pump! Never seen fuel. Retails for 520$. Looking to get 460$ for it by itself or 560 with both the inlet and outlet filters included (10 micron and 100 micron) |
