This is a standalone system designed for use with late-model LS Series (LS2/LS7/LS3) crate engines and is set-up to be plug-and-play with the engines as-received from GM Performance Parts – including operation of the latest electronic throttle control, EFI, and ignition systems.

The ECM is an OE unit used currently in many GM production vehicles but the calibration is custom and developed specifically for each crate engine family, so recalibration or tuning is not necessary.
Installation of the accelerator pedal (required for electronic throttle control), harness, oxygen sensors, and mass airflow (MAF) sensor is all that is required – add fuel and power and the engine is ready to run. The controller is also adaptable to any vehicle fitted with one of the engines mentioned. Yes, it comes with instructions. According to GMPP, these controllers will be available in early 2008 with the following part numbers: LS2 19166568, LS3 19201861, LS7 19166567.
Features of the system:
- Harness has an OE style fuse/relay center (fully populated with required items). To keep wiring clean and centrally-located, there are additional vacant fuse and relay positions.
- A 12-wire bulkhead connector is broken out of the harness and includes user outputs such as tach signal, vehicle speed signal (if a vehicle speed sensor is connected at the transmission), malfunction indicator light, fused ignition power, fused battery power, and oil pressure sensor. A mating connector allows these outputs to be tied-in cleanly without cutting into the harness.
- Cooling fan control – system will power a fan when coolant reaches 212 F
- Fuel pump is controlled by the ECM
- Controls late-model LS series alternators
System Caution:
- Be sure to mount the MAF Sensor per the guidelines in the instructions – this is critical for correct engine operation.
- Ensure the fuel pressure is a constant 400 kPa (60 psi) with the engine running – this is required for correct fuel control.
- Ensure the fuel pump has the following flow capability: Minimum 40 gph @ 400 kPa for LS2/LS3s
