GenBoard/VerThree install on Honda B16A2 engine


Trigger

There are 3 transmitters with toothcount 1,4,24 in the distributor (with honda PGM-FI ECM pin numbers):

As you see, autodata suggests that these are VR signals (amplitude increases with RPM).

If above is true (2 VR signals), the assembled ECM auditrigger configuration should be used without the cam-HALL connected.

Any confirmation would be welcome.

From the Honda service manual

Double check polarity because when I measured the pattern, hooked up this way the pattern went down instead of up.
