MSD Holley part number: 8260 (BB Chevy)
Haltech does not sell this part.
This crank trigger has a reluctor 4x tooth trigger system. Together with a cam sync signal it provides information to the ECU necessary to support sequential injection control. Being crank mounted it provides a much more accurate signal than a distributor based trigger system can.
When installing the kit for use with a Haltech ECU, the sensor should be located to give the most possible amount of ignition advance and then lock it down.
The TDC Offset should be found by using a timing light. A value of 40 will be close enough to allow most engines with this trigger system to fire up, but then it needs to be checked from there.
