MegaSquirt-II Sequencer™ Schematics
The MS-II Sequencer™ controller consists of three main parts:
- a "MicroSquirt®" section that is virtually identical to MicroSquirt and performs many of the calculations,
- a sequencing processor that uses the same processor but different code than MS-II™ and MicroSquirt® to distribute the ignition and injection signals appropriately, and
- a CPLD that is configured by sequencing processor and then does the pure spark routing when triggered by the IGN1 and IGN2 signals from the main processor.
A PDF file of the schematics is here.
MegaSquirt®, MicroSquirt® and MS-II Sequencer™ controllers are experimental devices intended for educational purposes.
MegaSquirt®, MicroSquirt® and MS-II Sequencer™ controllers are not for sale or use on pollution controlled vehicles. Check the laws that apply in your locality to determine if using a MegaSquirt®, MicroSquirt® or MS-II Sequencer™ controller is legal for your application.
