Vehicle Requirements
Vehicle Requirements
Maximum Vehicle Gross Vehicle Weight Rating (GVWR)
6.2 Liter LT4 engine- 6000 lbs. or less
Vehicle Speed Input
The ECM in each of these kits are not programmed identically and are not interchangeable. The ECM for the 4L/T56 is programmed and
looking for 40 pulses per revolution, typical of a GM automatic transmission. The T56 Super Magnum transmission is specifically built to
provide 40 pulses per revolution also. Both transmissions provide this input to the ECM via a sensor located in the tail shaft housing of the
transmission. The 8-speed transmission provides the VSS over the CAN
signal and the VSS sensor of the engine wire harness is not used. The ECM must have a Vehicle Speed Signal to operate the engine.
Axle Ratio and Tire Size Requirements
The axle drive ratio in the calibration is set to 3.42:1 and is suitable for a ratio from 3.08 to 4.11. Tire diameter needs to be between 26"
and 30".
NOTE: For optimal performance, choose an axle ratio and a tire size within the recommended range.
NOTE:
All LT4 E-ROD Engine kits are shipped with an automatic transmission flexplate and do not include the starter. For manual transmission
applications, the flywheel and clutches must be purchased separately. See www.chevroletperformance.com for all recommended Chevy
Performance transmission installation kits.
