Taking the Stealth name, all of the wiring exits below the rear fuel injector cover for a clean installation. The timed spark port for vacuum advanced distributors is located under the front fuel bowl, giving greater access to the distributor. Air entry is machined to fit most stock air cleaners with air cleaner locator provisions. The ECU features fuel maps that self-learn and integrated ignition timing control, yielding improved idle stability, drivability, and horsepower at wide-open throttle (WOT). The Stealth 4150 also includes transmission kick down provisions for GM TH350\/400, 200R4\/700R4, and Ford C4\/C6 applications for making installation more convenient. These kits provide plug and play transmission control for GM 4L60 and 4L80 transmissions.\u003c\/div\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003e3.5Ó LCD handheld touchscreen for setup, tuning, gauge displays, and other viewing parameters\u003c\/li\u003e\n\u003cli\u003eInitial handheld calibration wizard creates a base tune with no laptop needed\u003c\/li\u003e\n\u003cli\u003eAdvanced annular discharge rings for more fuel flow and better fuel atomization, nearly elimating the fuel delay issues found on other designs\u003c\/li\u003e\n\u003cli\u003eBosch LSU 4.9 Wideband Oxygen (O2) Sensor for maximum performance on real time fuel map learning\u003c\/li\u003e\n\u003cli\u003eOEM style TPS\/IAC robust design for longevity\u003c\/li\u003e\n\u003cli\u003eInternal 1 Bar MAP sensor built into the ECU\u003c\/li\u003e\n\u003cli\u003eBolt on 4150 flange carburetor replacement fits many factory intake manifolds\u003c\/li\u003e\n\u003cli\u003eAir entry is machined to fit many stock style air cleaners with air cleaner locator provisions\u003c\/li\u003e\n\u003cli\u003ePlug and play transmission control for GM transmissions\u003c\/li\u003e\n\u003cli\u003eIntegrated ignition timing control improves idle stability, fuel economy, and wide open throttle (WOT)\u003c\/li\u003e\n\u003cli\u003eAll wiring exits below the rear fuel injector cover for a stealth installation\u003c\/li\u003e\n\u003cli\u003eFor 24x or 58x GM LS engines\u003c\/li\u003e\n\u003cli\u003eFour inputs include 12V, ground, 5V, and frequency, for pressure sensors, activation triggers, trans brake, etc.\u003c\/li\u003e\n\u003cli\u003eFuel and Oil Pressure inputs are pre-terminated\u003c\/li\u003e\n\u003cli\u003eFour outputs include ground, PWN-, for fans, boost and nitrous control, IAC, etc.\u003c\/li\u003e\n\u003cli\u003e(4) 100 lb.\/hr. fuel injectors supporting up to 650 HP naturally aspirated or 600 HP on forced induction applications\u003c\/li\u003e\n\u003cli\u003eRequires an external fuel pressure regulator with base pressure set to 58.5 PSI (Holley P\/N 12-886 or equivalent)\u003c\/li\u003e\n\u003c\/ul\u003e\n\t\t\u003cdiv class=\"brandbox\"\u003e\n\t\t\t\u003cdiv class=\"brand-content\"\u003e\n\t\t\t\t\u003cp class=\"brand-title\"\u003eAbout Holley EFI\u003c\/p\u003e\n\t\t\t\t\u003cdiv class=\"brand-main\"\u003e\n\t\t\t\t\t\u003cdiv class=\"brand-image-container\"\u003e\u003cimg class=\"brand-image\" width=\"387\" src=\"\/\/images.holley.com\/387x\/brands_holley_efi_new_standard_fuel_background.jpg\"\u003e\u003c\/div\u003e\n\t\t\t\t\t\u003cp class=\"brand-text\"\u003eFind standalone EFI for LS, Coyote, Hemi and more at Holley.com.
