Variable CAM Module Specific Considerations
The Variable CAM Phase capability has module specific repercussions that must be considered when using this capability.
Resource Limitations
Depending on hardware, Variable CAM capability can be resource intense and require the use of additional resources above the allocated channel.
The list below states what resources become unavailable for each module target. If the module is not listed then it either does not support
Variable CAM, or there are sufficient free internal resources to provide the capability without impact.
'xx' in module name may be any number
ECU565-128
INJ11, INJ12 and EST12 are no longer available when the Variable CAM encoder is used.
ECU563-48-07xx
ECM-0563-048-07xx
ECM-0563-048-08xx
Internal A5 + B5 resources. These may conflict with MuxPSP if used.
HCM563-48-08xx
HCM-563-048-08xx
GCM563-048-08xx
Unsupported at this time
ECU555-80
INJ11, INJ12 (alias AIR5/AIR6) are no longer available when the Variable CAM encoder is used.
ECU555-48-xxxx
Internal A5 + B5 resources. These may conflict with MuxPSP if used.
Hardware Capability Limitations
Different modules have different internal capabilites. Some resources that appear in the list of resources of the Variable CAM Phase block may only support a subset of the possible variable cam phaser patterns. This is module specific.
ECU565-128
- DG1M, DG2M - Support a limited subset of the patterns including Halfmoon Variable Cam Phaser, PWM Variable Cam Phaser, and Equidistant Tooth Cam Phaser
- DG3M, DG4M, CAM - Supports all the available variable cams phasers.
ECU563-48-07xx
ECM-0563-048-07xx
ECM-0563-048-08xx
- DGxM - No digital inputs support VarCAM.
- CAM - Supports all the available variable cams phasers.
ECU555-80
ECU555-48-xxxx
- DG1M, DG2M, DG4M - Support a limited subset of the patterns including Halfmoon Variable Cam Phaser, PWM Variable Cam Phaser, and Equidistant Tooth Cam Phaser
- CAM - Supports all the available variable cams phasers.
