Engine Control Module and Harness
A precisely calibrated engine control module is essential to making your modern fuel-injected engine perform in your older vehicle. Unlike production controllers that may or may not come with a used engine, these controllers are calibrated for installation in older vehicles. That means many of the features required for late-model production vehicles are "turned off," because they're not required in older cars and trucks. That means features that may trigger a diagnostic trouble code and possibly affect performance - requiring additional tuning - are not enabled. These controller kits deliver all the components required to plug into the engine and get it running - from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors, and even a throttle pedal assembly. The kits also include detailed instructions to help you do it right the first time, even if you have no experience.
Installation Notes:
- Engines shipped with high-pressure direct-injection fuel pump installed
- Intended for pre-1976 street vehicles or any off-road vehicle
- Not intended for marine applications
- Front-End Accessory Drive Kit p/n 809-19329990 can be ordered separately
- 8-bolt crankshaft flange
- Shipped with 14 in. flexplate
- Each E-ROD engine requires a front-end accessory drive system suitable for the vehicle. The instruction manual includes recommendations for the accessory drive kit, as well as the transmission, gear ratios and more. Chevrolet Performance offers two configurations of the accessory drive systems to suit different applications; and each allows the installer to easily delete air conditioning.
- In addition to the E-ROD system, the builder will need to source additional components to complete the assembly and get the vehicle running.
- Fuel tank
- Fuel lines (re-circulating or returnless)
- High-pressure EFI fuel pump
- Electric fan
- Fuel tank vent line from the tank to the evaporative emissions canister
- Pure line from the canister to the engine purge solenoid
- Air induction system that incorporates the mass airflow sensor
- Exhaust system behind the catalytic converters
Engine Break-In Procedure
Use only engine oil that meets dexos1 specifications. For track events or competitive driving, use Mobil 1 15W-50 engine oil. Fill the engine with oil and follow the proper engine priming procedure. Also check and fill as required any other necessary fluids such as coolant, power steering fluid, etc.
Start the engine and listen for any unusual noises. If no unusual noises are noted, run the engine at approximately 1000 RPM until normal operating temperature is reached. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide open throttle (WOT) or sustained high RPM accelerations. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
Change the engine oil and filter. Inspect the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly. Drive the next 500 miles (12 to 15 engine hours) under normal conditions. Do not run the engine at its maximum rated engine speed. Also, do not expose the engine to extended periods of high load. Change the oil and filter again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning properly.
