Overview

The GM Performance 88962718 is an Engine Control Module (ECM) that is part of the Ram Jet 502 Fuel Injection Kit (P/N 12499249). This kit is calibrated for a 502/502 GM engine (P/N 12499121) and is designed for off-highway applications only. The ECM can be replaced with an aftermarket unit for use on other big-block applications with proper calibration. The kit includes the ECM along with brackets, sensors, bolts, nuts, gaskets, and other small parts for the fuel injection system. The Ram Jet 502 engine utilizes a speed-density fuel management system, with the ECM controlling fuel metering, ignition timing, idle speed, and on-board diagnostics based on inputs from various sensors (MAP, RPM, ECT, TPS, Knock Sensor).

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
